Google's agent-first development platform for building and shipping software with AI agents
A desktop app, a full agentic IDE, a terminal-first CLI, editor extensions, and an SDK let you run Antigravity agents wherever you already work.
Group conversations into Projects and run several local agents at the same time, across multiple workspaces, rather than one at a time.

Runs on Google's Gemini model line, including releases such as Gemini 4 Carbon, Gemini 4 Argon, and Gemini 3.8 Flash.
