What Is Antigravity
Google's agent-first IDE: an editor where agents do the work, and a mission control for running several at once.
Antigravity is Google's agent-first development platform — a free IDE launched alongside Gemini 3, built on one bet: the primary actor in your codebase is now an agent, and your job is to direct and verify it. It ships two surfaces. The Editor view looks like the IDE you know, with an agent in the side panel. The Agent Manager is the new thing: a mission-control board where you spawn, steer, and review multiple agents working in parallel across multiple workspaces.
Where Claude Code and Codex are single agents you converse with, Antigravity is built for the shift from IC to manager: you stop thinking in turns and start thinking in throughput. You brief agents; they work asynchronously at their desks (workspaces — your repos); and they report back with evidence. Not a wall of tool calls — artifacts: task lists, implementation plans, walkthroughs, screenshots, and browser recordings you can audit in minutes.
Agents in Antigravity control three things: the editor, the terminal, and a real Chrome browser. That last one matters — an agent that can click through the app it just built, screenshot it, and record the flow is an agent whose 'done' you can actually check.
