Publish what Cursor built for you.

The folder is all it needs

Cursor writes ordinary files into an ordinary folder. Point the app at that folder and it reads what is there: a static page, or a project with a build script it knows how to run. There is nothing to configure in the project and nothing to add to it.

It also notices Cursor has been working there, from the rules file Cursor leaves behind, and says so on the project.

Open the folder back in Cursor

The project card has a button that opens the folder in Cursor. It is a small thing, and it removes the most common way to waste ten minutes: hunting for the right folder in an Open dialog, or editing a copy of the site that is not the one you published.

See it before anybody else does

Press Start and the site opens at an address on your own computer — the built site, not the editor's preview. It is the same files that would go online, which is the point: if it is wrong here, it would have been wrong there.

What is checked before Cursor's work goes public

An AI writing code will sometimes write an API key straight into a file. Every publish is scanned first — source files and built output — and a key stops the upload before anything is on the internet.

When that happens the app names the file and the line, and gives you a prompt to paste back into Cursor that explains what to move and where.

Publishing, and publishing again

Choose Netlify or Vercel, connect your own account, and press Publish. You get a real address. When the site changes, the app notices the folder is ahead of what is live and one button catches it up — to the same address, so a link you sent last week still works.

Every publish is kept. If a change turns out badly you can make an earlier one live again, and nothing is rebuilt.

Step by step

1. Build the site in Cursor, as you already do.
2. Open the app and add that folder.
3. Press Start to see it on your own computer first.
4. Connect Netlify or Vercel — your own account — and press Publish.
5. Send the address to whoever asked for the site.
6. When they want a change: describe it to Cursor in the same folder, then press Publish again. The address does not change.
