Where to Host an App built with Claude Code (September 2026)

Claude Code does not host your app. It writes and runs the code on your own computer, and you send that code to a host to put it online. If your app saves nothing, a free static host like Vercel, Netlify, or Cloudflare Pages is enough. If it saves data or has logins, you need a full-stack host and a database.

The short version:

Claude Code writes the app on your computer. It does not give you a live URL.

An app that saves nothing can go on a free static host.

An app that saves data needs a server host and a database, which often means two accounts. O n Floot, the app is hosted as part of the build, and the live URL comes with the first build.

On other setups, Claude Code can run the deploy, but you pick the host, own the accounts, and move the secrets yourself.

The rest of this guide covers what a host gives you, which kind you need, what each host makes you do, and the one thing that breaks.

Hosting, in one picture

Think of Claude Code as a builder working in your garage. It can make anything, and it all works fine in the garage.

A host is a shop on a real street. It has an address, it stays open when you go to bed, and strangers can walk in. A static site is a poster in the window. A full-stack app has a till and a filing cabinet in the back.

The split exists because your laptop sleeps and has no public address.

"Running at localhost:3000" only works on your machine.

What a host actually gives you

A host does the jobs your laptop was doing quietly while you tested. It keeps the app running, on a computer that never closes its lid. It gives the app an address (something like yourapp.vercel.app), and you can point your own domain at it.

It holds your secrets. API keys go into the host's settings, called environment variables, instead of into the code.

It stores the data, if you add a database, either built in or from a service like Supabase or Neon.

It redeploys when you change things. Every push to GitHub puts the new version live.

Notice the pattern. Every one of those is something your laptop did for free, and it stops the moment you close it.

Does your app save anything?

Here is the quick test. Ask what happens when someone closes the tab and comes back tomorrow.

If nothing needs to be different, you can skip the server and the database. A landing page, a portfolio, a calculator, and a brochure site all go on a free static host.

If something needs to be remembered, you need a full-stack host and a database. That covers a booking app, a client portal, a tracker, a store, and anything with logins.

Not sure which one you have? Ask Claude Code: "List every service this app needs to run in production."

What each host makes you do

Every host follows the same path: push the code to GitHub, import the repo, add your secrets, and deploy. Claude Code can do the typing, but you create the accounts. S tatic hosts are the easy case. Full-stack hosts ask more: Railway and Fly.io bill by usage, Render's free tier sleeps, and Vercel plus Supabase or Neon means two accounts and two bills.

The pattern is the same everywhere it goes wrong: the app works on your laptop, then going live sends you off to pick a host, a database, and a place to keep your keys.

Floot hosts the app for you as part of the build, so there is no host to pick. You describe what the app should do, and Claude Code builds it onto Floot: pages for the frontend, small server programs called endpoints for the backend ("create a booking," "list my invoices"), and a Postgres database for what it remembers. The live URL comes with the first build.

Because Floot also includes the database, logins with Google, Microsoft, and email, file storage, email sending, scheduled jobs, and live updates, the pieces you would otherwise rent from a host, a database service, a login service, and an email service are already there. You never sign up for anything else.

FAQ

Does Claude Code host my app?

No. Claude Code writes and runs code on your computer, and you need a separate host to put the app online.

Where can I host a Claude Code app for free?

For a static site, use Cloudflare Pages or Netlify. Full-stack free tiers usually sleep, expire, or cap usage.

Can Claude Code deploy to Vercel?

Yes. Claude Code can push your repo to GitHub or run Vercel's command-line tool, but you create the Vercel account and sign in yourself.

Why does my Claude Code app only work on localhost?

Localhost is your own computer. Nobody else can reach it until the code, keys, and database are on a host.

How much does it cost to host a Claude Code app?

A static site can be free. A full-stack app with a database typically starts around $5 to $25 a month, and usage-based plans rise with traffic.

Does Floot host the app for me?

Yes. Floot builds and hosts the full stack, including the database and logins, and the live URL comes with the first build.
