Antigravity Is Google’s New Agentic Development Platform

Google today launched Antigravity, its latest experiment in building an agentic development platform. Powered by the new Gemini 3 model, Antigravity combines what has become a pretty standard AI-centric IDE with a few innovations that, according to Google, evolve the IDE “towards an agent-first future.”

Antigravity will be available for free in public preview for Mac, Windows and Linux starting today, with what Google calls “generous rate limits” for Gemini 3 Pro usage.
