# History and undo

> Every edit is saved in history. Roll back to any version of your site.

Every edit is saved in history. You can review everything you did with the site, and roll back to any version if needed.

## Undo last edit

The "Undo" button in the builder header rolls back the last edit and rebuilds the site in \~10 seconds. Press multiple times in a row. After Undo, "Redo" appears if you change your mind.

## Version history

The "History" section keeps all site versions with timestamp, edit description, and author. You can:

* Preview any old version.
* Roll back to any version with one click.
* Compare two versions: see exactly what changed.

## Start over

If you really don't like the current project, create a new one with a refined description. Old projects stay in "My sites" and don't disappear.

<Tip>
  Don't delete old projects right away. Sometimes it's useful to come back to an early draft and grab a good section from it.
</Tip>

## Download project copy

In the builder's top bar there is a **Code** button. Open it, at the bottom-right of the code panel you'll find a **Download** button that produces a zip archive of the whole project. Use it for archival copies or to hand off to a developer.
