Key differences
Who it's for. Bolt is for people who want to describe an app and see it running without setting anything up. Antigravity CLI is for people who already have a project and want an agent to read it, edit files and run commands.
Where the code lives. With Antigravity CLI the files are on your computer, in your own folders, and you decide how to run and publish them. Bolt keeps you in the browser and handles building and publishing.
Safety. With a terminal agent you should keep a git safety net, see our git guide.
