Free hosting for vibe-coded apps
From localhost to everyone’s screen.
You built an app with Claude Code, Codex or Cursor, and it only runs on your machine. Ask your agent to publish it here. A few minutes later it has a public link for anyone, its own database and a live line to everyone who has it open, so people can play, chat and post in it together.
- Free
- No sign-up
- No credit card
- Nothing to install
Three steps from localhost to a public link
- Step 1
Connect once
Add one address, a remote MCP server, to Claude Code, Codex, Cursor or whichever agent you work with. It takes under a minute and you only ever do it once.
- Step 2
Ask it to publish
Tell it to put the app online here. It packs up your app, deploys it and checks that it answers - no GitHub repo, no deploy pipeline, no Docker.
- Step 3
Share the link
You get a public address and a private editor link. Send the first to anyone. Keep the second, it is how you change the app later.
Not just hosting. A database and multiplayer, built in.
Most hosts hand out a copy of your app to each visitor, and everybody plays alone: what one browser keeps in localStorage, the next one never sees. Here every app has its own database and a live line to everyone who has it open. A move one person makes shows up for all the others straight away, and what they post is still there tomorrow.
No Supabase or Firebase to sign up for, no backend to wire in, no server to rent. Ask for it the way you would describe it to a friend.
- Multiplayer games“Let up to eight friends join the same round and see each other’s moves live.”
- Chat rooms“Add a room where everyone with the link can talk, and keep the last hundred messages.”
- Shared lists“Turn the packing list into one the whole team edits at once.”
- Leaderboards“Keep a leaderboard with everyone’s best time and show the top ten on the start screen.”
- Little social networks“Let wedding guests post photos to one wall and like each other’s.”
The shortest way from “it works” to “try it”
Vercel, Cloudflare and Lovable are great places to run things. They also start with a sign-up form, and the moment your app needs to share anything between visitors, with a second service to set up. Here is how it looks when you start from nothing.

Connect Claude Code, Codex or Cursor once
Give your agent the address of our MCP server. From then on it knows how to publish here, no key and no sign-in needed.
https://genhttp.dev/mcpRun this once in a terminal. From then on, Claude Code can create and change apps here from any project.
claude mcp add --transport http genhttp https://genhttp.dev/mcp
Using something else? Windsurf, Codex, Zed and most other agents can add a remote MCP server in their settings. Give them the address above.
Then, in your project, say something like
Give it a domain of its own
The same app, the same editor link, but served at an address you own. Easier to say out loud, easier to remember, and it looks the part when people start sharing it.
Ask about your domainBefore you publish
Is it really free?
Yes. No sign-up, no credit card and no trial. Your app stays online for as long as people use it. After 30 days without a single visit or change it is taken offline, and after 90 it is removed.
Can Claude Code, Codex or Cursor deploy my app here?
Yes, and any other agent that can add a remote MCP server. Connect it once with the address above, then ask it to publish: it deploys the app, checks that it answers and sends you the link.
Why can’t my friends open my localhost link?
Because localhost is your own computer: the address only works there, and only while the app is running. A tunnel lends it a public address for as long as your laptop stays on. Published here, the app runs on our servers with a link that keeps working when your laptop is closed.
Do I need a server, a backend or Supabase?
No. Every app gets its own database, file storage and a live line to everyone who has it open. There is no server to rent and no second service to set up - and nothing to keep running on your side either.
Can I make my game multiplayer without running a server?
Yes. What one browser keeps in localStorage the next one never sees, so the shared part has to live on a server - here it is ours. Ask your agent to make the game multiplayer, and every move reaches everyone who has it open.
Does my app have to be built a certain way?
No, your agent takes care of that. Pages, pictures and styles go up as they are, and anything that has to run on the server is adapted by the agent for this platform. You describe what the app should do and it does the translating.
How do I change it later?
With the editor link you got when it was published. Hand it to your agent with the next change, or open it in your browser. Every change becomes a new version at the same address, and you can go back to an older one at any time.
Where do my API keys go?
Not into the code. Your agent asks for a key by name, and you type the value into the editor. Nobody reads it back - not the editor, not the agent.
Can I take my code with me?
Yes, it is yours. Download it from the editor whenever you like, as a project that runs on its own, database included.
Who can see my app?
Anyone you give the link to. It is not listed anywhere unless you choose to add it to the showcase.
Is there anything I cannot publish?
A few things, like anything that harms or deceives people. The terms are short and in plain words.
It works on your machine.
Let it work on theirs.
Free. No sign-up. Nothing to install.
