Publishing an app built with Cursor AI

AI builders are good at generating a site and less good at getting it online. Once you've got the files, publishing takes about a minute.

Steps

1. Export or download your project from Cursor AI.
2. Find the build output — the folder containing index.html.
3. Zip that folder's contents.
4. Drag the zip onto the upload area at tiiny.host.
5. Choose a link name and click Publish.

Skip the export entirely

If you're working in Claude, you can publish straight from the chat without downloading anything — see How to connect to the MCP server with Claude.
Or skip the AI builder too: Create with AI generates a project and publishes it in the same place. Available on every plan including free.

The app works locally but not once published

Usually one of two things:

• It needs a backend. We host static files only — anything requiring a server, database or server-side code won't run. See Databases and Tiiny Host.
• The zip structure is wrong. index.html needs to be at the top level of the zip.
