How to host a Claude-generated web app

Short answer: Claude builds the app; it can’t host it. To put a Claude-generated web app online, connect Claude to a host built for it — like Croft — and ask Claude to deploy. A minute later it’s live at its own web address, with a database and a login, ready to share.

Here’s the wall people hit. Claude will happily build you a working app right in the chat — an artifact. It looks like software. But an artifact runs only in your chat window, for you, with nothing saved and no link to share. The moment it’s genuinely useful, you need a home for it.

The steps

1. Connect Claude to your croft — a one-time setup. In Claude, go to Connectors and add Croft. Full guide →
2. Ask Claude to build and deploy. Describe what you want — “build me a booking app and deploy it to my croft” — or take the artifact you already have and say “deploy this as an app.” Claude writes it and ships it.
3. Open the link and share it. It’s live at its own URL, on HTTPS, behind your login. Invite the people who need it; they sign in once.

Why you need a host, not just Claude

A hosted app has the three things an artifact doesn’t: a live web address anyone you invite can open, a real database so what people enter is saved, and a login so it stays private to your people. On Croft, all three are built in — you don’t set up a server, wire up auth, or manage a database. Claude builds; Croft runs it.

That’s the whole loop. See how it works →
