Connect Hostus and ask Claude to publish the game on Hostus. You get one link that opens on any phone, stays the same on every version, and asks your friends for no account. It works on every Claude plan, Free included.
Claude can also share some things by itself, and the rules differ between chat, Claude Code and Cowork. They changed in September and again this month, so the table below separates them. Anthropic facts come from Share artifacts, What are artifacts, Use live artifacts in Claude Cowork and the Claude Code docs, read on 7 November 2026.
What can each Claude product share by itself?
| Where you made it | How to share | Who can open it | What it means for a game |
|---|---|---|---|
| Hostus, from any of them | Connector or file, on any Claude plan | Anyone with the link, once you make it public | Rooms and leaderboards work, and the link stays the same |
| claude.ai and Claude Desktop | Share, then Anyone with the link, on Pro, Max, Ultra, Team and Enterprise. Not on Free | Most open without a Claude account | Saved data stays hidden from people who aren't signed in. Artifacts that connect to other websites can't use this link |
| Legacy artifact, made in a chat before 16 September 2026 | Publish, on Free, Pro, Max and Ultra | Anyone with the link, no account | You can't make new ones, and unpublishing can't be undone |
| Claude Code | Share in the page header, on Pro, Max, Ultra, Team and Enterprise | Anyone with a public link, with no sign-in. They see "Content is user-generated and unverified." | One page with no backend. Requests and WebSockets reach only the page's own origin and Google Fonts |
| Cowork, paid plans | Made on or after 19 August 2026: same as claude.ai | Same as claude.ai. Live artifacts made before that date stay inside your organization | Same as claude.ai |
On Team and Enterprise, artifacts stay inside the organization until an owner allows outside sharing. You can't change sharing settings in the iOS or Android apps.
Publish from claude.ai, Claude Desktop or Cowork
Connect once. Anthropic says custom connectors work on every plan, and Free is limited to one. On Team and Enterprise an owner adds it first.
- Go to Customize > Connectors, click + Add, then Add custom connector.
- Paste
https://app.hostus.io/api/mcp. - Sign in with your Hostus email and click Authorize. No API key.
Then, in the conversation:
- If Claude doesn't see it, open the + button, then Connectors, and turn Hostus on.
- Ask in plain words:
Make a car game for 4 players and publish it on Hostus.For a game you already have:Publish this game on Hostus. - Claude gives you the link. The page starts private, so open your Hostus dashboard, make it public, then send the link.
Keep going in the same conversation: Make the jump a bit higher and update the same link. Claude publishes with hostus_upload, updates with hostus_update and reads what went wrong on players' phones with hostus_review.
Publish from Claude Code
The game is already a file on your disk. In the Hostus dashboard, open MCP & API, create a key, and add the connector:
claude mcp add --transport http hostus https://app.hostus.io/api/mcp --header "Authorization: Bearer YOUR_KEY"Then ask: Publish game.html on Hostus. The page starts private here too, so make it public in the dashboard.
No connector? Take the file out and upload it
- In the conversation with your game, paste the game prompt. It asks for one
.htmlfile with everything inside, under 1.8 MB, with touch controls for phones. - Get the file. On claude.ai, Anthropic lists view, copy and download controls for legacy artifacts and an Export button for artifacts made from a template. For any other artifact, ask Claude for the full code and save it as
game.html. In Cowork, finished work waits in your session to preview and download. - Drag the file onto hostus.io, type your email and click the magic link. That drop takes files up to 1 MB. For a bigger one, sign in first and upload from the dashboard.
- Make the page public, copy the link and paste it in the group.
Which one should you use?
Hostus is our pick for a game your friends will play more than once. It works on the free Claude plan, playing needs no account, and a leaderboard or a room for 8 works for people who never heard of Claude. Update the game every night and the link stays the same.
Claude's Share button. Pick it if you are on a paid plan, the game runs alone in one page, and it keeps nothing between players.
A public link from Claude Code. Pick it for a single-player page you already built there, if your friends don't mind the "user-generated and unverified" label.
Want friends playing at the same time?
Ask for rooms: up to 8 players join from an invite link, with no other account or key. See multiplayer with friends and a leaderboard for your game. Both are already in the game prompt. Rooms need the published link, so test them on Hostus and not in Claude's preview.
Play one first
Flipdot is a one-tap arcade game published on Hostus, with a leaderboard and no backend. Open it on your phone: this is what your friends get when you send the link.
Good to know before you publish
Every page shows a small Hostus badge, and you pick the corner. The link is yourgame.hostus.page, and you can't point a domain of yours at it. The page does not appear in Google, so people reach it from your link. A new page starts private: making it public is a switch in the dashboard. The free plan covers 20 pages and 2 MB, media included, and Hostus keeps the last 20 versions of each page. If the file has a secret key in it, the upload stops and warns you. A Firebase web config also raises a warning, and it is public by design, so you can go on. Only publish games that are yours. Hostus gets your game to your friends. It is not a storefront: nobody finds your game on Hostus, and there are no payments. Home screen, player errors and the new version notice work on public pages Hostus detects as games.
