AI game makers compared: what each one actually builds
Every AI game maker turns a description into something you can play. What differs is what you are left holding: a link on their site, an engine project, or a file you own.
Jump to a section
An AI game maker turns a written description into a playable game, usually one that runs in a browser. Rosebud AI, PlayDrop, Websim and Astrocade build games that live on their own sites and are shared by link. SEELE exports Unity 6 projects on its Pro plan. Replit lets you download the project as a zip. A chat window with ChatGPT, Claude or Gemini hands you the file itself.
Which one suits you depends less on how clever the model is than on that difference. A game on someone else's site can be shared as soon as it works. A game you hold as files can be moved, edited by hand and published anywhere.
To share something today, use a hosted maker. Rosebud and PlayDrop both start free. To keep the game, look for the download. Rosebud puts it on its Pro plan at $50 a month, SEELE puts Unity export on Pro, and Replit offers a zip. To own one file from the first answer, ask a chat window for a single HTML file.
What does an AI game maker actually build?#
Every AI game maker starts the same way. You describe a game in plain words, the AI builds it, and you play the result. The differences begin after that, with where the game is kept and who is able to change it.
The top row is where most makers sit, and it is a sensible place to start. The game is hosted for you, the link exists the moment the game works, and other people can remix it. What you give up is the file. If the service changes its plans or closes, your game changes or closes with it.
The lower rows trade some of that ease for control. An exported project or a downloaded zip can be opened, edited and hosted somewhere else. A single HTML file goes furthest, because a browser opens it directly and nothing else is needed.
AI game makers side by side#
Every cell below comes from the maker's own website, pricing page or documentation, read on 14 October 2026. Where a maker's pages are silent, the table says so rather than guess.
| Maker | What it builds | Where the game lives | Taking the files with you |
|---|---|---|---|
| Rosebud AI | 2D, 3D and voxel games, written in JavaScript on three.js | Rosebud's own hosting, shared as a link | Code download and a Windows build from the Pro plan, $50 a month |
| PlayDrop | 2D and 3D browser games, solo or multiplayer | PlayDrop, as a public, unlisted or private game | Not stated for games built there. It does accept HTML files and zips made elsewhere |
| Websim | Interactive games and web pages | A Websim project page and its feed | Not stated on its own pages |
| Astrocade | Casual games, built by describing them | Astrocade's feed, open to remixes | Not stated on its own pages |
| SEELE | 2D and 3D game prototypes, with generated art, music and sound | The browser on three.js, or Unity | Unity 6 packages on the Pro plan |
| Replit | Games as web apps: platformers, endless runners, strategy games, stories | A Replit project you launch from there | Download as zip, from the file tree menu |
| Unity Spark | Games in an editor, from Unity | Not stated. It is a closed beta with a waitlist | Not stated |
| A chat window | A game in one HTML file, if you ask for one | A file on your own computer | It is a file from the first answer |
Read the last column first. It decides whether the game can ever leave the service it was made on.
Several of the comparison pages that come up for these searches are published by one of the makers being compared. Makko, Summer Engine and Cinevva each list their own product first, and Cinevva says so openly. Agent Games is not a game maker, but it does publish games that AI models wrote. It gains when you build a game you can upload, so weigh the last row with that in mind.
What each AI game maker builds, one by one#
Rosebud AI#
Rosebud builds 2D, 3D and voxel games in the browser, on three.js. You describe the game, it writes the JavaScript, and you change it by chatting. Published games get a link anyone can play, and any published game can be remixed. Viewing and editing the code in the browser starts on the Indie Dev plan at $15 a month. Commercial rights start on 10x Dev at $30 a month.
PlayDrop#
PlayDrop builds 2D and 3D browser games, for one player or several. It says its builds use models from OpenAI, Anthropic, Google and xAI, depending on plan and effort setting. Each new version stays private until you choose Publish, and then you pick public, unlisted or private. PlayDrop also takes games made elsewhere: an HTML file, a zip, a folder, or a game sent by an AI agent through its MCP connector.
Websim#
Websim describes itself as a place to create and share interactive games and web pages. You type an idea, the AI writes the code, and you post the result to a feed where others can like, comment and remix it. When it ended its free daily credits in January 2026, it said free models were still available. Since July 2026 its build agent can also run on your own ChatGPT account, which Websim does not charge for.
Astrocade#
Astrocade calls itself a social gaming platform where anyone can build, share and play AI games, with no coding or downloads. Its own summary says you describe a game in plain language, and several specialised AI agents handle the visuals, interface, mechanics and animation. Other creators can build on and change games from the community. Its pages say nothing about taking a game's files elsewhere.
SEELE#
SEELE builds 2D and 3D game prototypes and generates the art, music and sound effects to go with them. Games run in the browser on three.js, or export as Unity 6 packages with C# scripts and asset folders. Unity export and commercial use both need a Pro plan, and the free tier runs on starter credits.
Replit#
Replit is a general app builder with a game page of its own. It turns a prompt into a playable game, from platformers and endless runners to strategy games and interactive stories, and launches it with no setup. You can build from a phone as well. The project can be downloaded as a zip from the file tree menu. Its game page names no engine or library.
Unity Spark#
Unity Spark is Unity's own AI game maker, described on its page as having a real editor. Its tagline is prompt it, perfect it, publish it. For now it is a closed beta, and the only way in is a waitlist. Its page does not yet say where finished games can be published.
A chat window#
ChatGPT, Claude and Gemini are not sold as game makers, but each will write a complete game when asked for one self-contained HTML file. The file is yours from the first answer, and you can open it, edit it and host it anywhere. The trade is that you paste errors back yourself. The method is in how to make a game with AI, with separate guides for ChatGPT, Claude and Gemini.
Which AI game maker lets you keep the files?#
This is the question the product pages answer least clearly, so here it is in one place. Each line is what the maker itself says.
- Rosebud AI: project code download, and a Windows build you can publish on Steam, start on Pro at $50 a month. Lower plans have no download.
- SEELE: Unity 6 packages with C# scripts, models and asset folders, on Pro. You open them in Unity and carry on there.
- Replit: Download as zip, from the three-dot menu at the top of the file tree.
- PlayDrop: its docs do not mention downloading a game built there. Files do go the other way. It imports an HTML file, a zip or a folder, and its connector accepts an index.html of up to 5 MiB from an AI agent.
- Websim and Astrocade: neither one's own pages mention exporting a game.
- A chat window: the answer is the file, so there is nothing to export.
Files matter for three practical reasons. You can host the game somewhere else. You can edit it by hand when the AI keeps getting one detail wrong. And you can publish it on more than one site, including Agent Games, where an upload is one HTML file or a zip of up to 30 MB.
Being able to download a game is a separate question from being allowed to sell it. Rosebud includes commercial rights from its 10x Dev plan at $30 a month. SEELE says commercial use needs an active Pro plan. Read the terms of whichever maker you use before you charge anyone for a game.
Is there a free AI game maker?#
Yes, several start free. But a free plan is an allowance of credits, and the number that matters is what one change costs. Here is what each maker says its free account includes, set against its own price for a single step.
Rosebud's free plan gives 8,000 credits a week, refilled weekly in eligible regions. A turn with Rosie, its default AI, costs about 2,000 credits, so a free week is about four turns. A turn with a premium model costs about 20,000, which is more than a whole free week.
PlayDrop lets every account claim 50 credits a day, and the claims stack up to 350. A Light task costs 100 and a Max task costs 1,000. Its own FAQ notes that a game can need several tasks. Quests and one-time rewards add more credits on top. Its paid plans are Plus at $20 a month and Pro at $100 a month.
Websim ended its free daily credits in January 2026, and said at the time that free models were still available. Its other free route is its ChatGPT build agent, which runs on your own ChatGPT account. Websim says a free ChatGPT account works for it. SEELE gives starter credits and shows the cost of each generation before you continue. Replit's game page invites you to start free, and Unity Spark's page gives no price.
Which AI model is doing the work?#
Behind every maker is a language model, and some of them say which. PlayDrop names its providers. Rosebud prices its default model and its premium models a factor of ten apart. Websim will run its build agent on your own ChatGPT account. So the model is a large part of what you are paying for.
That makes the model worth checking before the maker. The made-with pages on Agent Games group games by the model that wrote them. Each game page names the model, and the prompt and tokens too when its maker shared them.
Opus 5.5
GPT-6 AstraEvery game in that row was written by an AI model and published here. Open two or three, and read the prompt on each page where the maker left one. Together they show what people asked for and what came back.
How to choose one in five minutes#
If you want to share something today and move on, a hosted maker is the shortest route. If the game should still be yours to change in a year, you need the files, so start from the last column of the table.
Find the credit cost of a single turn or task, and divide the free allowance by it. On Rosebud that is about four default turns a week. On PlayDrop's daily claim it is one Light task every two days.
Commercial rights are a plan feature on some makers. Rosebud includes them from 10x Dev, and SEELE from Pro.
Rosebud, PlayDrop, Websim and Astrocade all show games people made with them. Play three before you sign up, and judge those games rather than the landing page.
If the maker names its models, look up games by those models on the made-with pages. If it does not name them, that is worth knowing too.
Common questions#
What is the best AI game maker?
There is no single best one, because they build different things. For a game shared by link today, Rosebud and PlayDrop both start free and host the result. For a Unity project, SEELE exports one on its Pro plan. For a file you own outright, ask ChatGPT, Claude or Gemini for one HTML file.
Is there a free AI game maker?
Yes. Rosebud gives 8,000 credits a week and PlayDrop 50 a day to claim. SEELE gives starter credits, and Websim's build agent can run on a free ChatGPT account. Check what one change costs before deciding how far the free plan goes.
What is the difference between an AI game maker, generator, creator and builder?
In practice the words name the same kind of tool. Rosebud and PlayDrop call themselves AI game makers, while Replit and Astrocade say AI game builder. What separates them is what they hand back, not what they are called.
Can an AI game maker build a 3D game?
Yes. Rosebud builds 3D and voxel games on three.js, PlayDrop builds 3D browser games, and SEELE builds 3D prototypes that can go to Unity. A chat window can also write a three.js game in one file.
Do I need to know how to code?
No. Every maker here works from a plain description, and Rosebud, PlayDrop and Astrocade all say no coding is needed. PlayDrop's own FAQ adds that you still decide what makes the game fun and playtest it, and that the first version may need changes.
Can I sell a game made with an AI game maker?
Sometimes, and it depends on the plan. Rosebud includes commercial rights from its 10x Dev plan and SEELE from Pro. PlayDrop lets players tip your games and splits in-game purchases 50/50. Read the terms of the maker you used before charging anyone.
Is there an AI game maker app for my phone?
Some. Replit says you can build and play from a phone, and PlayDrop has a PlayDrop Games app on iOS and Android. Aippy's Google Play listing calls it an AI game maker to create and play mini games.
Where can I publish a game I built with AI?
On the maker you built it with, if it hosts games. If you hold the files, you can upload them elsewhere too. On this site that means one HTML file or a zip of up to 30 MB, free with a verified account, or a coding agent can publish it for you.
Where to go next#
If you want the file, start with how to make a game with AI, which covers the brief, the first prompt and the fixes. The prompt guide has complete prompts to paste into any chat window or maker. For depth and a camera, the 3D guide covers three.js, and the 3D games here show where it leads.
When the game is done, publish it on Agent Games, or let a coding agent do it through the MCP endpoint. Its page will name the model that wrote it.
