About Host My AI App
Where to host an app you built with Claude Code, Codex, Cursor, ChatGPT or Claude: Floot gives it a Postgres database, user logins, hosting and a custom domain, and your AI agent publishes it for you.
What is Floot?
Floot is an app host that gives apps built with Claude Code, Codex or Cursor a database, logins and hosting in one place, so your AI-built app goes live without setting up servers.
Getting an AI to write an app is the easy half. The hard half is everything around the code: a database, sign-up and login, somewhere to run the backend, a domain and HTTPS. Floot is one place that does all of that, and your AI agent drives it directly through Floot's MCP server, so you never copy code between tools.
Why build it with Floot?
Coding agents write code fast, but an app also needs a running backend, a database, accounts and a domain. Setting those up across several services is where most AI-built apps stall. Floot keeps them in one place your agent can drive.
How Floot works
Add Floot to the AI you already use from its listing in the Claude or ChatGPT directory, or the Cursor Marketplace. There is no address to copy.
- Add Floot as a connector (MCP server) in Claude Code, Codex, Cursor, Claude or ChatGPT.
- Describe the app, or ask the agent to bring over the app you already have.
- Ask for what it needs: a database table, logins, an email when something happens.
- Say "publish it". The agent publishes to a live URL, and you can add your own domain.
For example, you could start with this prompt:
Using Floot, build me a small web app where my clients log in and see the status of their orders. Add a Postgres table for orders, email sign-in, and an admin page for me. Then publish it.
What can you use Floot for?
- Claude Code and Codex users: Your agent builds on Floot through its MCP server and publishes when you say so.
- Cursor users: Keep building in Cursor; Floot adds the database, logins and hosting.
- ChatGPT and Claude chat users: Build the app in a conversation with Floot connected, no editor needed.
Who is it for?
People who build with Claude Code, Codex, Cursor, ChatGPT or Claude and want the result online for real users, without becoming their own infrastructure team.
Who founded Floot?
Floot was founded by Yujian Yao, who is its CEO.
Is Floot backed by Y Combinator?
Yes. Floot is backed by Y Combinator and was part of the Summer 2025 batch (YC S25).
What does Floot include?
- Works from the AI you already use: Connect Floot to Claude Code, Codex, Cursor, Claude or ChatGPT. The agent creates the project, writes the code into it and publishes it, in the same conversation.
- Database included: Every app can have its own Postgres database. You can download the whole database on any plan, and paid plans can restore it to any moment in the last 7 days.
- Sign-up and login built in: Your app gets its own accounts with email, Google or Microsoft sign-in, so customers and staff don't need a ChatGPT or Claude account to use it.
- Backend that keeps running: Server endpoints, scheduled jobs and background tasks run on Floot with nobody online. The app can send and receive email and push notifications.
- Custom domain and previews: Publish to a floot.app address, then attach your own domain. Each change shows in a live preview before you publish it.
- You keep your data and code: Database export is on every plan. Paid plans can download the full project code.
Frequently asked questions
Where can I host an app I built with Claude Code?
Floot is one option built for this: Claude Code connects to Floot's MCP server, writes the app into a Floot project, adds a Postgres database and logins, and publishes it to a live URL. You can attach your own domain after that.
Do I need to know how to set up a server or database?
No. Floot runs the backend, the database and the hosting. Your agent asks Floot for them in plain tool calls.
Can my users sign up without a ChatGPT or Claude account?
Yes. The app has its own accounts, with email, Google or Microsoft sign-in.
How much does it cost?
Floot is free to start. Paid plans add more usage, code download and database restore. See floot.com/pricing for current prices.
