I wanted to like it as a Gemini Pro subscriber who does not want to also pay for Claude Code, but after running Antigravity for ~ 10 minutes, and a few back and forward exchanges I got the 'Model quota limit exceeded' message with no indication when it will reset. You get the impression that these products from Google (including Gemini CLI ) are just made as prototypes -- they are supposed to work as a demo, but Google does not actually care about having a working workflow with them. Claude Code on the other hand is an actual product that works well.
