The Best Desktop Pet Apps in 2026: 27 Options, Honestly Compared

Why most “best desktop pet” lists won't help you

The desktop pet space has a discovery problem. The three places people usually look each fail in a different way.

Where people look	What you get	What's missing
Steam tags and store search	A flat, unsorted pile of paid apps	No comparison, no free/open-source options, and no answer to “can it load my model?”
YouTube “top 10 desktop pets” videos	Nice footage, often from 2021–2022	Stale by the time you watch it, and rarely says which apps still get updates
Reddit threads	Honest anecdotes from real users	Scattered across threads, and nobody maintains the list six months later
This page	27 apps, 11 categories, one verdict each	You still have to decide what you want — that part can't be outsourced

The other problem is vocabulary. “Desktop pet” covers at least four different things: an animated sprite that wanders your screen, a 3D avatar you can dance, a Tamagotchi-style creature you feed, and an animated wallpaper that isn't a character at all. Lists that mix them without saying so are why people install something and uninstall it ten minutes later.

So every entry below is sorted by where the character comes from and how much it can do — not by download count. Prices, platforms and GitHub star counts carry a checked date, and the whole list gets revised every six months.

Picking by platform: almost everything here runs on Windows. On macOS your realistic options are AniMate Waifu (native Apple Silicon), Desktop Mate (public beta since June 2026), Bongo Cat (Steam build supports Mac), Shimeji forks, plus the open-source AI group — OceanPet, HermesPet and Project AIRI. On Linux, look at Shimeji forks, ayangweb/BongoCat, Oneko and Project AIRI.

The list: 27 desktop pets, reviewed

Prices, platforms and star counts below were last verified on 2026-08-21 unless a row says otherwise. Sources are listed at the end.

① Open-standard pets (VRM) — your character, not the developer's

How to choose in this category: you want your character rather than a studio's, and you want it in 3D with AI chat and dancing. The one prerequisite is a VRM model — but VRM models are easy to get for free (make one in VRoid Studio, or download from the usual model sites). Commercially, this category has exactly one turnkey option. On the open-source side you can get there with AIRI from category ⑥, but you'll be running the stack and configuring APIs yourself.

1. AniMate Waifu

Setup is three steps: get a VRM file, drop it on the app, and the character is on your desktop. It doesn't lock you to a franchise — it's a character container. Import whoever you want, and swapping characters means swapping files instead of buying them one at a time.

The cleanest way to describe the difference from the rest of this list: most desktop pets decide which character you get. AniMate Waifu lets you decide. In practice that means:

• Any VRM model: VRM 0.x and 1.0 both import. The free tier ships with two built-in characters; the full version unlocks custom imports plus a performance asset library, with motions, dances and stages managed in one place with 3D preview.
• It remembers you: real-time text and voice chat with cross-session memory. Open it a week later and it still knows what you talked about — this is the line between a character and a rule-based chatbot.
• It dances: any imported character can be put into the same choreographed dance, with a motion library and stage assets for performance clips.
• It stays out of the way: transparent window, click-through, and a quiet mode, so it can sit in a corner permanently without stealing a single click.

The trade-offs are worth stating plainly: the full version is a one-time $9.90, not free software; you supply the VRM models yourself (the app points you at sources and licensing guidance); and it runs on Windows 10/11 and macOS on Apple Silicon.

Who it's for: people with an OC, a favourite character, or a model they've rigged themselves; anyone who wants a companion that remembers them; creators who want their character to dance on camera.

Price / platforms: free tier with two built-in characters; $9.90 one-time for the full version. Windows 10/11 and macOS (Apple Silicon). Available from getanimate.app or the Microsoft Store.

Why it leads this list: out of 27 apps, it's the only one that combines your own 3D character, AI chat with memory, dancing for any character, and click-through desktop presence — and does it without a setup guide. Compare that to the alternatives: official-character pets lock you to their catalogue at $14.99 a character, VPet and Shimeji are 2D sprite systems, and the open-source AI projects expect you to run the infrastructure. If what you want is a 3D character container that works the moment you install it, there's one complete option in 2026.

② Official-character pets — you get what the studio made

How to choose in this category: you want studio-quality models and voices and you're happy for the developer to choose the character. Do the maths first: characters run around $14.99 each, and the total climbs fast once you have favourites. Importing your own character isn't supported.

2. Desktop Mate

A paid-character desktop pet from the Japanese studio infiniteloop (Steam app 3301060, launched January 2025). A studio-modelled 3D character sits on your desktop, follows your cursor around, perches on your taskbar, and supports voice lines, mouse interaction and alarms. The base app is free; characters are sold as DLC. It passed 1.4 million downloads in May 2025, 1.9 million by the studio's March 2026 announcement, and crossed 2 million in June 2026 — the loudest desktop pet product on the market right now.

What works:

• Studio-grade consistency: models, voices and animations all come from one pipeline, with a steady flow of crossovers — Hatsune Miku, Megurine Luka, 2B from NieR, Sanrio, Touhou Project, Kizuna AI. By July 2026 there were more than 36 DLC characters (SteamDB).
• The base app is free: add it to your Steam library and you get the mascot character included. Since June 2026 she has voice lines too — the studio says all characters are now fully voiced.
• Mac support arrived: a public macOS beta launched on 24 June 2026 (requires macOS Tahoe 26 and Apple Silicon M1 or better; multi-character display and some other features are still missing).
• It keeps shipping: in July 2026 the team released a companion app, a free calculator pet that has the character read numbers aloud and pose, with a performance mode where Miku sings with your number keys (that character is a $2.99 DLC).

What doesn't: characters cost about $14.99 each, and the community joke about that price is well earned — a few favourites and you've spent real money. There's no official support for importing your own VRM, so modding means third-party loaders like Custom Avatar Loader, which updates regularly break (one GitHub issue title says it outright: “New DesktopMate Update broke the mod.”). Users have also reported high CPU usage on the Steam forums. The Mac build is new and incomplete.

Who it's for: people who want official characters and will stick to one or two of them; Miku, 2B and Sanrio fans.

Price / platforms: free base app plus per-character DLC; Steam, Windows (macOS in beta).

Verdict: the quality benchmark for official characters. It's the mirror image of AniMate Waifu: one sells you the characters, the other lets you bring them. Neither is wrong — they're answering different questions. Full cost breakdown: what Desktop Mate's DLC really costs.

③ Open-source raising games — free, and you pay in patience

How to choose in this category: budget is zero and you enjoy tinkering. Be clear on the cost: “free” here usually means installing mods and configuring APIs yourself, and the character style is mostly 2D. If you want a 3D character that works out of the box, this category won't get you there.

3. VPet Simulator

The most approachable open-source desktop pet: LorisYounger/VPet on GitHub (6,678 stars, Apache-2.0, checked 2026-08-21), with a free Steam release (app 1920960, August 2023) sitting at Overwhelmingly Positive. Around 199MB, Windows. It began as the built-in pet in a virtual-streamer simulator and was later split into its own project — and the developer works on it full time, which shows: the repo's most recent commit was 18 August 2026, with a steady release history on Steam before that.

What works: it's genuinely free and open source, so you can change anything in the code; interactions include head pats, picking it up, wall climbing and feeding (the animation above is the head pat); the mod scene is mature, with a free official mod-maker DLC plus Steam Workshop support for animations, items, behaviours, themes and code plugins; and it keeps gaining features — a photo gallery landed in late 2024, birthday and Qixi tags in 2026.

What doesn't: the character is a 2D sprite sheet, and swapping it means Workshop content or editing code — you can't import an arbitrary 3D model. The advertised animation count (32 × 4 × 3) isn't fully implemented, as the README itself notes. AI chat requires configuring your own API and has no voice or memory. Memory use and occasional crashes are recurring complaints in the issue tracker, and the setup is involved enough that the project's own documentation warns about it.

Who it's for: people with a zero budget who like modding; developers who want something to build on.

Price / platforms: free and open source; Steam, Windows. Download from GitHub Releases or Steam — third-party “VPet mobile” builds floating around are not official.

Verdict: the best-value desktop pet in this list, with a community that's still active this month. The split with AniMate Waifu isn't quality, it's layer: a 2D sprite sheet animating versus a 3D character performing. Free-first users should start here. More: VPet alternatives compared.

4. CodePet

A desktop pet for programmers (GitHub: jnMetaCode/codepet). Write code, use Claude Code, and it gains experience, levels up, changes state, dances and pops speech bubbles on your desktop. It only reads your local git commits and ~/.claude usage, processes everything locally, and can be switched off in one click — your output literally feeds the pet.

What works: tying a desktop pet to your coding output is a genuinely fresh idea, and the local-only privacy design is the real selling point. Apache-2.0, and the author is active in developer communities.

What doesn't: it's meaningless to anyone who doesn't write code. And it's very early — the repo was created on 17 June 2026, has 23 stars, and the last commit was in late June (checked 2026-08-21). Treat it as a promising seedling, not a daily driver, and accept that it may go quiet.

Who it's for: developers and AI-coding users who want company while they work.

Price / platforms: free and open source, distributed via GitHub and npm.

Verdict: part of the broader “AI coding companion” wave of 2025–2026. One warning: there's an unrelated VS Code extension and a commercial product also called “Code Pet”.

5–6. mea-pet-public and lom_pet

• mea-pet-public (open source, personal project): the author describes it as “very incomplete, but it cost a lot of tokens”. Verdict: interesting as a look at how a solo developer works, not recommended as your main pet — “incomplete” is the author's own judgement.
• lom_pet (open source, a fan pet for a streamer's character): the usual rule for fandom pets applies — delightful if you're a fan of that character, irrelevant if you're not.

④ 2D sprite classics — the lightest option, and the least capable

How to choose in this category: old hardware, nostalgia, or you just want something small moving on screen. These are genuinely tiny (tens of megabytes at most), but there's no chat, no 3D and no dancing. Ideal as a second pet or a piece of history — not as your main one.

7. Shimeji

Named after the shimeji mushroom, Shimeji is the original 2D sprite pet: a Java app from 2008 that sends tiny characters crawling across your desktop, hanging off window edges and multiplying when you right-click. The original is long abandoned, but forks keep it alive — Kilkakon's Shimeji-ee has been the mainstream build for years, and there's been fresh work recently: DalekCraft2/Shimeji-Desktop moved the runtime from JRE 6 to JDK 25 (still committing in mid-2026, on Windows, macOS and Linux), Shijima-Qt is a Java-free Qt rewrite available on Flathub, and there's even an experimental fork wiring Shimeji into an AI chatbot.

What works: it's tiny — around 26.57MB in download-site listings, trivially light on any machine; the core loop is still fun, and long-time users will tell you about the time a hundred sprites took over the screen; and the sprite packs are freely swappable, with Vocaloid, Genshin and Demon Slayer sets widely available.

What doesn't: the Java runtime is a real barrier, and plenty of newcomers stall there (there are packaged builds with Java bundled, which is the easier route); interaction is shallow — crawling, hanging, being dragged and thrown, with no chat, no 3D and no dancing; and because the original is dead, the experience is fragmented across forks with different feature sets.

Who it's for: nostalgia, low-spec machines, and anyone who just wants small characters wandering the screen.

Price / platforms: free; Windows, macOS and Linux depending on the fork.

Verdict: the ceiling of lightness and the floor of capability. It's the ancestor of the entire category, and it's a different era from a 2026 AI pet — worth installing as a second pet, and worth remembering as proof the format has lasted 18 years. Stick to GitHub, Flathub and official sources; a number of “official” download mirrors have been flagged as suspicious. To move up to 3D: Shimeji alternatives.

8. eSheep

What it is: a pixel-art sheep that walks along your desktop (listed at 0.63–2.98MB on download sites — about as small as this gets).

Verdict: even more nostalgic than Shimeji, and even simpler. The upside is that it costs nothing in resources; the downside is that it does almost nothing. For desktop-decoration minimalists only.

⑤ Meme and prank pets — maximum presence by design

How to choose in this category: streaming, pranking, or making your friends laugh. Their shared trait is presence — enough of it to steal your mouse and your attention — which is exactly why they don't belong on a work or study desktop. If you want quiet company, go to category ① or ⑥.

9. Bongo Cat

A white cat that drums on bongos, plays piano and honks a trombone along with your keystrokes. The meme dates to 2018 and the idea has been re-released several times; the 2025 Steam version sent it up the charts again, breaking into Steam's top five concurrent games within a month of launch (alongside CS2 and PUBG) and peaking at nearly 200,000 concurrent players in May 2025 according to SteamDB. As of August 2026 it has more than 100,000 Steam reviews and an Overwhelmingly Positive rating.

What works: it responds instantly to typing, which makes it a natural for streams; critics have described it as a gamified pomodoro timer, since every 30 minutes of typing drops a hat. There are several builds — the free Steam version on Windows and macOS, a browser version with no install, an OBS overlay version for streamers, and a well-maintained open-source desktop build by ayangweb (22,714 stars, MIT, Windows/macOS/Linux). It's tiny (4–15MB in download-site listings) and it added a multiplayer mode in August 2025 where up to 100 cats drum together, plus in-game chat in April 2026.

What doesn't: the character is fixed — you can't change the cat. And the gameplay is “reacts to your keyboard”, not companionship. Because it monitors keystrokes globally, Steam forums periodically ask whether it's a keylogger, so it's worth installing only from Steam, the official web version, or the GitHub repo.

Who it's for: streamers and anyone who wants their typing to feel less solitary.

Price / platforms: free on Steam (optional cosmetic packs); Steam on Windows and macOS, plus web and third-party open-source builds.

Verdict: a meme that became a product, and an unusually honest one — the developer told Eurogamer the game loses money, with about $2,000 net in its first month and a best month of $4,050, less than one developer's salary, as a funnel towards their next game. It will never remember you or talk to you, because it isn't trying to. More: Bongo Cat alternatives.

10. Desktop Goose

What it is: a goose that waddles across your screen, drags in memes, leaves muddy footprints and fights back when you try to move it. Free on Windows and macOS, made by samperson, inspired by Untitled Goose Game.

What works: the prank is fully realised, and the reversal of “you are tormenting the goose” into “the goose is tormenting you” is what made it spread. It's free and configurable, and you can add your own meme images.

What doesn't: it's genuinely disruptive — it grabs the mouse and drags windows — so it's unusable while working. Multiple geese will slow a machine down; the official instructions tell you to be careful.

Who it's for: people who find it funny rather than annoying, which is the whole test.

Verdict: the other landmark of the meme-pet category. Its design goal is to bother you, so it's the opposite of a companion. More: Desktop Goose alternatives.

⑥ Open-source AI companions — best privacy, biggest setup

How to choose in this category: this is where developers, privacy-conscious users and AI tinkerers should look. They all share one trait — you supply the model and the API, so your data never leaves your machine, and you pay for it in configuration. If you want out-of-the-box behaviour with a 3D character and memory, this category can't give you that; that's category ①.

11. Project AIRI

What it is: an open-source AI companion (GitHub: moeru-ai/airi, 48,189 stars, MIT, checked 2026-08-21 — it went from around 20,000 to nearly 50,000 in a single year, the fastest-growing project in this space). Real-time voice conversation, the ability to play games with you (Minecraft, Factorio, Kerbal Space Program), self-hosted, running on web, Windows, macOS and Linux, installable on desktop via winget, brew or nix.

What works: it's the most popular open-source AI companion by a wide margin; self-hosting gives you the best privacy here; playing games alongside you is its signature trick; it now supports both VRM and Live2D character models, with auto-blinking and gaze tracking; and the ecosystem is busy, with something committed almost every day.

What doesn't: you configure the model and API yourself — it connects to 30-plus LLM providers, but you're the one signing up — so the setup is a real hurdle. The whole project is agent-first and self-hosted, which means installation is the beginning, not the end: memory, voice and appearance all need tuning. Documentation, updates and support come from the community.

Who it's for: developers, technically minded users, privacy-first users, and people who want an AI to play games with them.

Price / platforms: free and open source (MIT); web, Windows, macOS, Linux, self-hosted.

Verdict: the benchmark of open-source AI companions. The interesting part is where it differs from AniMate Waifu — not whether it can show a 3D character (it can), but approach. AIRI hands you parts; AniMate Waifu hands you an assembled product. Choose AIRI to build something yours, choose AniMate Waifu to just use it. Background: AI desktop pets compared.

12. OceanPet

What it is: a native macOS AI pet (GitHub: cpp285/OceanPet, 40 stars, MIT — the repository was created on 12 August 2026, so this is brand new). Written in Swift and SpriteKit, with character animation, gaze tracking towards the cursor, wandering, voice wake-up, DeepSeek conversation and local note search.

Verdict: a useful combination for Mac users — native app, DeepSeek, and it can search your own notes. But it's a week old at the time of checking, covers macOS only, and still falls in the “bring your own API” bucket.

13. Alife

What it is: a desktop pet built as an AI agent (GitHub: BDFFZI/Alife, 156 stars, AGPL-3.0, C#/.NET — still committing on 2026-08-21, so small but alive). One-click install, very low overhead, a single permanent session, plugin-based throughout, and it can even write its own plugins.

Verdict: aimed at people who want to raise an agent rather than install a character. The one-click installer is unusual for open source, and the plugin architecture plus its deliberate transparency about context are the interesting parts. The ecosystem is new, you still supply the model, and the community is tiny.

14–17. oc-pet, dsh-kun-like-pet, Desktop-pet and airi-avatars

• oc-pet (open source, PySide6): a transparent pet with AI chat and frame animation. Verdict: a lightweight project to play with if you're comfortable configuring a model.
• dsh-kun-like-pet (open source, a plugin for a coding harness): switches between nine poses based on what your agent is doing. Verdict: a tool-ecosystem accessory — interesting as a crossover between pets and dev tooling, invisible to everyone else.
• Desktop-pet (git2968, open source, 12 stars): Live2D plus AI chat plus MCP extensions. Verdict: triggering expressions from AI replies is a nice touch, and offline voice input was there from the first version; but it's small, needs your own API key, and is early.
• airi-avatars (open source, part of the AIRI ecosystem): an avatar container driven by an LLM with real-time voice, in the browser or on desktop. Verdict: a deep-cut component for people already invested in AIRI.

18. HermesPet

What it is: an open-source desktop AI companion (GitHub: basionwang-bot/HermesPet, 597 stars, checked 2026-08-21) written natively in Swift 6 and SwiftUI for macOS 14 and up. Its pitch is living in your MacBook's notch: no dependencies, multiple engines in parallel (DeepSeek, Kimi, MiniMax, OpenAI and others), click to chat, hold to talk, drag in a file for it to read, with data stored locally.

What works: native Swift performance, switchable engines, a spell on GitHub's trending list, and commits as recently as July 2026.

What doesn't: macOS 14+ only, no licence field in the repo (so commercial reuse is unclear), and it's a chat companion rather than a 3D character — no VRM, no dancing.

Verdict: a strong native Mac AI companion; just be aware it answers a different question from a character on your desktop.

19. PetDock

What it is: a hackathon project from OpenAI's Build Week (listed on DevPost, submitted July 2026) that turns photos of your pet into a companion living on your desktop — the tagline is “Your pet just got a desk job”. Built with Codex and GPT (Node.js, optional local ComfyUI for image generation), it has a complete flow: upload, pick a mood, preview, download, and a demo mode that works without an API key.

What works: the idea, and the honesty — the author documents the hard problems (generation consistency, background removal, keeping the character recognisable).

What doesn't: it's a prototype the author describes as “early but working”, with nothing publicly downloadable. Not usable day to day yet.

Verdict: one of the early signals for AI-generated pets — even hackathon teams are building “photos into a desktop pet”.

20. Codex desktop pets

What it is: pets built by prompting a coding agent such as OpenAI's Codex (there are projects like Codex-Kiana-Pet-Enhancer, plus community tutorials along the lines of “build a coding companion in an hour”, checked August 2026). You describe the character, sprite work, animation and behaviour, and the agent writes it.

What works: the ceiling on customisation is high, since the pet is code you own and can keep editing — and the results are shareable.

What doesn't: you need to be comfortable with Codex or another agent, and the output quality varies enough that you'll be debugging it.

Who it's for: developers and people already living in AI coding tools.

Verdict: the DIY end of AI-generated pets. What you get is a pet with fixed behaviour; what you don't get is a container you can swap characters into, or memory across sessions.

⑦ Commercial AI pets — deliberately not ranked

There is a growing shelf of closed-source AI pets sold on Steam and app stores. We're not listing them individually, and that's an editorial decision rather than an oversight: they change pricing and features constantly, their chat and memory behaviour is opaque, and none of them lets you bring your own character. Everything you'd want from them exists in a better form elsewhere in this list — open-source projects in category ⑥ if you want control and privacy, or AniMate Waifu if you want AI chat and memory built in and inspectable.

If you're weighing one up anyway, three questions will tell you most of what you need to know: does it charge a subscription for chat, does the character remember previous sessions, and where do your conversations go? A “free and unlimited AI” desktop pet is a funnel, because inference costs money somewhere.

⑧ IP and fandom pets — built for one character

How to choose in this category: these exist for the fandom. Their value is the character; the recurring weaknesses are a single feature set, no 3D or VRM support, and dependence on a fan project staying alive. Buy them for love of the character, not for a daily companion.

21. ArkPets

An Arknights-themed pet (isHarryh/Ark-Pets, GPL-3.0, official site arkpets.harryh.cn). It's more than a reskin: it implements a 2D gravity field, so operators can be thrown around and will balance on window edges; there's a transparent click-through mode, launch-at-startup, about 50–80MB of memory use, and a model library that keeps growing. The limitation is Windows only, with macOS and Linux still in progress. Free.

⑨ Live2D viewers — the 2D rigging ecosystem

How to choose in this category: you want a Live2D (2D animation) character on your desktop. If you want a 3D character that turns and dances, that's category ①. The two ecosystems don't mix.

22. Live2DViewerEX

What it is: the established viewer and desktop tool for Live2D models (Steam app 616720, Pavo Studio; early access in 2017, full release in 2022). Three display modes (wallpaper, desktop, desktop window), support for Windows, macOS, iOS and Android, high-precision face tracking, Workshop content, and a $4.99 one-time purchase. Still receiving updates in May 2026, including Spine 4.3 support and full Apple Silicon compatibility, with a Very Positive rating across several thousand reviews.

Verdict: Live2D is a 2D animation format — flat, layered, with a paper-cutout feel — and a different world from VRM's 3D rigs. It's an independent tool with no affiliation to Live2D Inc. The common mistake is assuming anything that loads a model gives the same result; the gap between 2D and 3D is larger than it sounds. Details: 2D versus 3D desktop pets.

⑩ Animated wallpapers (for reference) — moving is not the same as reacting

How to choose in this category: these appear constantly in desktop pet searches, so they're here to draw the line. If you want a desktop that moves, look here. If you want a character that responds to you, none of these are pets.

23. Wallpaper Engine

What it is: the paid animated wallpaper engine (Steam app 431960): video, 3D and web wallpapers with a huge Workshop library, $4.99 with frequent sales, more than a million Steam reviews at Overwhelmingly Positive, an estimated user base in the tens of millions, full Windows/macOS/Linux support, and a free Android companion app. Still updated in 2026.

Verdict: it's a background layer. It animates; it doesn't interact, chat or remember you. It's the standard for desktop decoration and no substitute for company — which is exactly why it's in this list.

24. N0va Desktop (miHoYo)

What it is: miHoYo's 3D animated desktop (official site n0va.mihoyo.com, Windows and Android, free). The virtual idol Lumi is rendered live in Unreal Engine on your desktop; you can click her for reactions, change outfits, watch dance practice, and browse an official wallpaper library for Genshin Impact and Honkai.

Verdict: visually the most impressive thing in this category, and clearly built as desktop decoration rather than a conversational companion. Fun if you're a miHoYo player; not an AI companion.

⑪ Classic toys and desktop tooling — the original, and the near-misses

How to choose in this category: the 1989 original, plus the two Windows tools that keep getting recommended as desktop pets even though they aren't. If you're a Unix veteran, start with Oneko — it's the reason this whole category exists.

25. Oneko

What it is: the original desktop pet. Neko — “cat” in Japanese — is a small pixel cat that chases your mouse cursor, curls up and sleeps when you stop moving, and scratches itself if you leave it alone. It was written in 1989 for the NEC PC-9801 and ported to X11 soon after, and because of that it shipped with or beside countless Unix systems, which is why a generation of developers remember it as their first desktop pet. It's free and open source, and the idea outlived its platforms: today you'll find maintained forks for macOS and Windows, plus oneko.js (around 1,300 stars), which puts the same cat on a web page.

Verdict: worth installing purely to see how little a desktop pet needs to be charming. It's the historical argument behind this entire list: a cat that follows your cursor has been enough to make people smile since 1989 — everything since has been adding capability to that idea.

26. Lively Wallpaper

What it is: a free, open-source animated wallpaper app for Windows (GitHub: rocksdanister/lively, 19,621 stars, GPL-3.0, C#). Videos, GIFs, web pages and applications as wallpaper, including interactive content.

Verdict: the honest answer to “do I have to pay for Wallpaper Engine?”. If you want a moving desktop and prefer open source, this is it. Same caveat as category ⑩ — a wallpaper is a background, not a companion, even when what it displays is a character.

27. Rainmeter

What it is: the long-running Windows desktop customization tool (GitHub: rainmeter/rainmeter, 6,014 stars, GPL-2.0, C++), with a skin ecosystem covering system monitors, launchers, clocks and assorted animated decorations — including a number of character skins.

Verdict: included because search results mix it in with desktop pets constantly, and because a lot of people who want “a character on my desktop” actually want Rainmeter plus a skin. It's a customization engine, not a pet: no AI, no interaction model, no memory. If you enjoy building your desktop, it's excellent; if you want a companion, it isn't one.

How this list is maintained

Desktop pets move fast — the open-source AI wave is two years old, and even the 2008 projects are still shipping forks. So this isn't a set-and-forget article:

• Rechecked twice a year (January and July): new releases added, abandoned projects removed, prices and platform support re-verified, categories and verdicts updated.
• Inclusion bar: a verifiable source (official site, Steam page or GitHub repository) and real users. Projects with neither don't make the list.
• Full history: every revision is logged below.

Changelog

Version	Date	Changes
v1	2026-08-13	First release: 11 categories with per-app verdicts and 9 illustrations, including AI-generated pet workflows and the HermesPet and PetDock entries
v1.1	2026-08-15	Rewritten to cut template feel: real user feedback and community detail added with sources (Steam reviews, GitHub issues, press coverage); Bongo Cat's origin year corrected from 2019 to 2018
v1.2	2026-08-21	Full re-verification: Project AIRI stars corrected (about 22k to 48k) plus its VRM and Live2D support; Desktop Mate updated with the 2 million download announcement, the macOS beta and its calculator companion; PetDock entry rewritten after source verification; repository data added for the open-source projects; numbering unified
v1.3	2026-09-10	English edition. Localised rather than translated: entries that only exist for the Chinese market and can't be verified from public Western sources were removed, category ⑦ was changed from a named list to an unranked category note, and three entries English-speaking readers actually use were added — Oneko, Lively Wallpaper and Rainmeter. 27 apps across 11 categories.

Next revision: January 2027.

Downloading safely: three checks

A list this long means a lot of download links, and desktop pets are a favourite target for bundled installers and repackaged builds. Three checks cover almost everything:

1. Verify the source. Official sites, Steam and the Microsoft Store. If a page offers a “high-speed download” for something free, check the domain before clicking — desktop pet downloads are frequently re-bundled with adware.
2. Read the installer. Uncheck anything optional. Official installers for these apps are usually clean; repackaged ones rarely are.
3. Trust the OS warnings. Pay attention to SmartScreen and Defender flags, and after installing, check the version number and file size against the official page.

Two specifics worth knowing: AI-generated executables are more likely to be flagged by antivirus, sometimes wrongly, so treat them with more caution rather than less; and anything that monitors input globally, like Bongo Cat, should only ever come from its official channel.

Frequently asked questions

What is the best desktop pet software for Windows?

It depends on one thing: whether you want your own character. If you do, AniMate Waifu is the only turnkey option — it imports any VRM 0.x or 1.0 model, adds AI chat with memory and dancing, and costs $9.90 once. If you're happy with someone else's character, Desktop Mate has the best-produced ones at about $14.99 each. If the answer is “free”, VPet Simulator is the strongest free option, and Shimeji the lightest.

Which desktop pets support my own VRM model?

AniMate Waifu imports any VRM 0.x or 1.0 model directly and manages motions, dances and stages alongside it. Project AIRI also supports VRM as well as Live2D, but you're running a self-hosted stack to get there. Desktop Mate, the largest official-character pet, does not support importing VRM models — only unofficial loaders do, and updates break them regularly. VPet Simulator uses 2D sprite sheets and cannot import VRM either.

Where can I download desktop pets safely?

Official developer sites, Steam and the Microsoft Store. Free pets are the highest-risk category because they get repackaged most often; avoid third-party download portals and bundled installers, and verify the file size and version against the official page after installing.

What is an AI desktop pet, and does it need the internet?

An AI desktop pet adds conversation to a desktop character, usually via a large language model. Whether it needs the internet depends on where the model runs: self-hosted open-source projects like Project AIRI can run fully offline, while built-in chat features typically call an API and therefore need a connection. If privacy matters, check where the conversations go before installing — and treat “free and unlimited AI” as a warning sign, since inference has a real cost.

Does AniMate Waifu support voice chat and memory?

Yes to both. It supports real-time text and voice chat, and memory carries across sessions, so the character remembers earlier conversations rather than resetting every time you open it. That combination — chat, voice and cross-session memory attached to your own 3D character — is the shortest description of what it does.

Do I need a good GPU for a 3D desktop pet?

Not a powerful one. A simple VRM character in a small window renders fine on integrated graphics. What raises requirements is model complexity, window size, frame rate and effects — so on weaker hardware, cap the frame rate, lower the quality setting and keep the character window small. 2D pets like Shimeji and Bongo Cat barely register. If something is already misbehaving: desktop pet performance troubleshooting.

Is VPet Simulator free, and can it import VRM?

It's free and open source (Apache-2.0), available on Steam and GitHub. It cannot import VRM — the characters are 2D sprite sheets, and changing them means Workshop content or editing code. Its AI chat also requires configuring your own API key.

Are there desktop pets for Mac?

Fewer than Windows, but enough: AniMate Waifu runs natively on Apple Silicon; Desktop Mate entered public macOS beta in June 2026 (macOS Tahoe 26 with M1 or better); Bongo Cat's Steam build supports macOS; Shimeji has active macOS forks; and the open-source AI group — OceanPet, HermesPet and Project AIRI — are all Mac-capable.
