Google Antigravity is an agentic IDE built on a forked VS Code that lets AI agents autonomously plan, write code, run the terminal, and test in a browser with minimal hand-holding. It pairs with Google Stitch (their text-to-UI design tool) to form a full design-to-code pipeline. Available free in public preview with generous Gemini 3 Pro limits; also supports Claude and OpenAI models.
