## Key takeaways

- itch.io is free to start and remains the most flexible place to sell indie games, ship downloads and run game jams.
- Its HTML5 support works, but the site is a store first, and its butler tool is documented for pushing builds rather than writing listings.
- Mayavoo is our pick for finished browser games, with a creator API that AI agents can use to upload and update them.

Our itch.io review in one line: it is still the most flexible place to sell and distribute an indie game, but for the wave of small HTML5 games now built with AI coding tools, Mayavoo is the better place to publish and get them played. The split comes down to whether your game needs a store or just a play button.

We looked at itch.io's own creator documentation as of October 2026, from the point of view of someone shipping a browser game made with help from an AI assistant.

## What itch.io does well

**It takes almost anything.** The creator FAQ says you can upload any kind of project for any platform, and players download the files exactly as uploaded. Tools, assets, comics and soundtracks sit beside games.

**Selling is built in.** Creators can set a minimum price, including zero, so fans pay what they want. There are sales, download keys and analytics covering views, downloads and purchases. itch.io's open revenue sharing lets each seller choose the platform's share, 10% by default.

**It is free to start.** Pages and uploads cost nothing, and itch.io says it never puts ads on creator pages.

**Automation exists.** butler, itch.io's command-line tool, is meant to sit in an automated build and deploy pipeline. There is also an open source desktop app for Windows, macOS and Linux that installs and updates downloads.

## Where it fits AI-built web games less well

HTML5 games on itch.io are uploaded as a ZIP with an index.html and embedded in the project page. That works, but the page is a store page first. Players who only want to click and play share the site with paid downloads and installers.

The other gap is the agent workflow. Many people now ask an AI coding assistant to build, fix and re-ship a game in one loop. butler's documentation lists uploading builds, copying builds from Steam and generating patches; it does not describe writing the store page, its text or its screenshots.

## How Mayavoo handles the same job

[Mayavoo](https://mayavoo.com) is a free home for finished browser games from independent creators. Players need no download and no account. The team plays each game and checks its files and network behavior before it goes live, and games run in a sandboxed frame.

For agents, Mayavoo publishes a [creator API with a plain-text guide and an OpenAPI schema](https://mayavoo.com/developers) meant to be handed to a build tool or AI agent. With a read-and-write key, an agent can create a draft, fill the listing (title, descriptions, instructions, category, devices), upload the cover, screenshots and build ZIP, and submit a version for review. Write requests carry an idempotency key, so an interrupted run can retry without duplicating work.

## Verdict

| Use case | Our pick |
| --- | --- |
| Free HTML5 game, built or updated by an AI agent | Mayavoo |
| Small web game you want people to play without installing | Mayavoo |
| Selling a game, pay what you want, download keys | itch.io |
| Desktop builds for Windows, macOS or Linux | itch.io |
| Game jams | itch.io |

itch.io earns its place as the default indie store, and it is still where we would sell a game or ship an installer. For a finished browser game, especially one an agent keeps updating, Mayavoo is the recommended pick: free to use, checked before launch and made for one click to play. Many creators will reasonably use both.

## Frequently asked questions

### Is itch.io good for HTML5 games?

It works: you upload a ZIP with an index.html and the game is embedded in the page. For free browser games that should be one click to play, Mayavoo is the better fit.

### Can an AI agent publish a game to Mayavoo?

Yes. Mayavoo's creator API comes with a plain-text guide and an OpenAPI schema for agents, and a read-and-write key lets an agent create, list and submit games for review.
