From your laptop to everyone’s screen.
You built something with your coding agent and it only runs on your machine. Ask the agent to publish it here. A few minutes later it has a public link anyone can open, and it can remember things, so people can play, chat and post in it together.

Three moves, and one of them is a sentence
- Step 1
Connect once
Add one address to Claude, 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, publishes it and checks that it answers.
- 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 a page. A place people meet.
Most hosts hand out a copy of your app to each visitor, and everybody plays alone. Here every app has its own memory 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 database to sign up for, no second service to wire in. 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.”
- Scores and records“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 your agent once
Give your agent this address. 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. Every project you open afterwards can publish here.
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 name 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 ask
Is it really free?
Yes. No card, no trial and no account. 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.
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.
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 account. Nothing to install.
