Antigravity

Antigravity is Google's agentic development platform. The organising idea is that the developer's job shifts from writing every line to directing agents and reviewing their output, so the interface is built around managing several agents at once rather than editing one file at a time.

How it is structured

• Agent Manager. A mission-control surface where you dispatch tasks, watch agents work in parallel, and review results — separate from the editor view.
• Editor view. A familiar IDE for the moments when you want to write code yourself.
• Browser control. Agents can drive a real browser to validate their changes against the running application, not just against the test suite.
• Artifacts. Instead of raw logs, agents produce readable plans, screenshots, and recordings of what they did, which makes review tractable.
• Model choice. Powered by Gemini, with other frontier models selectable for specific tasks.

Who it is for

Developers who already delegate substantial work to agents and are hitting the limits of a single chat thread. The parallel-agent model and artifact-based review are the differentiators. Available for macOS, Windows, and Linux with a free tier and generous rate limits.
