Can Claude host my game?

No. Claude writes the code and you choose where it runs. claude.ai can share an artifact by link, but a copy on a host you control is easier to update and list.

Does a Claude game have to be a single HTML file?

No. One file is the simplest to host and works well for small games. Larger games use a build tool such as Vite, and you upload the output folder.

My Claude game is blank when I open the file. Why?

Browsers restrict some features, such as module imports, for files opened from disk. Serve the folder from a local web server and read the browser console for the error.

How do I keep Claude from rewriting parts of the game that already work?

Ask for changes to named functions or files only, commit before each request, and ask for a summary of what changed. If a request goes wrong, return to the last commit.

Can I list a game on Foundplay that I built with Claude?

Yes, if the game is yours and plays in a browser at a link. Foundplay fills in the title, description and cover from the page, and you can add a source link.

I built a game with Claude. Where do I share it and get players?

Claude gives you code in a chat or a project built by Claude Code, and neither one hosts the game. Save the output as a folder or a single HTML file and put it on a static host you control. Then list that link on Foundplay, which keeps a list of games made with Claude that shows what others have built.

Two ways to build, two ways to ship

In a chat, Claude writes the code and you save it. Ask for a single HTML file with the style and script inline and no outside libraries, save it as index.html, and open it. With Claude Code, which works inside your project folder and can run commands, ask it to set up the build and a deploy configuration for the host you picked. Long games may hit a limit on the length of a chat reply, so ask for the game in parts, or have Claude Code write the files directly.

One HTML file is a fine game

A single file has no build step and goes on almost any host, including a zip on itch.io. The catch is that browsers block some features when you open a file by double-clicking it. If your page uses <script type="module"> with imports and shows blank, serve the folder from a local web server instead, for example with npx serve, and open the address it prints.

Working with Claude Code on a game that is live

Write the game's rules, file layout and the things that must not change in a CLAUDE.md file, so each session starts with them.
Work on a branch and deploy a preview. Merge when the preview plays well on a phone.
Ask it to name the functions it changed and to write down the steps to check each fix.
Ask for automated checks on the parts that must not break, such as scoring and win conditions.

What to post

Write the pitch yourself. A post about how you built the game with Claude reaches people who build, and a clip of the game reaches people who play. Use both, in different places. Say what you asked Claude for and what you changed by hand if people ask. The AI games guide lists what to check before you share.

How Foundplay can help

Foundplay is a game discovery platform for free browser games. It doesn't host games: every listing sends players to the creator's own site.

The free listing

Listing a game is free. Paste the link where people play it at /submit, check the details and publish. The game goes live right away, and Play sends players to your own site.

The source link field can hold your repository or the prompt that started it. Foundplay lists games made with Claude next to every other kind of browser game.

Boost, the paid option

Foundplay sells Boost, so it has a reason to want you to buy it. The free listing works without it.

For a new release, the plan called Boost puts the game on its genre pages and in search results. Because those pages hold all kinds of browser games, a boost reaches people who came to find something to play, not only people who follow AI tools.

The Boost plan costs $10 for 120 plays in 5 days, which works out to 8.3¢ a play. Where it shows: its genre pages and search results.

A play is a counted click on Play from a sponsored spot, the same way public play counts work: once per game per network a day. Every sponsored spot is labelled Sponsored, and the share of plays not delivered by the end of the plan's days is refunded automatically. Foundplay can't see what players do after the click. Fan games and copies of commercial games can't be boosted. A game has to be listed before it can be boosted. List it first, or start a Boost and add your play link there, and Foundplay lists the game for free as part of the same flow.

For scale, Foundplay's own visit counter shows an average of 4,500+ visitors a day over the last three full days, and 600+ games are listed. It updates every few minutes.
