What is Google Antigravity?

Antigravity 2.0, launched at Google I/O on May 19, 2026, is Google's agent-first development platform: a standalone desktop app where several agents plan, write, run, and verify code in parallel, plus a Go-based CLI that replaces Gemini CLI, an SDK for embedding the agent harness, and Managed Agents in the Gemini API that run in isolated Linux environments. Gemini 3.5 Flash is the default model; a free tier signs in with a Google account, and paid access comes with Google AI Pro and Ultra plans. Gemini CLI consumer access ended June 18, 2026.
