Google Antigravity is Google's agentic development platform, announced alongside Gemini 3 in late 2025. Built as a modified VS Code fork, it combines a traditional AI-powered editor with a Manager View for orchestrating multiple autonomous agents working in parallel across workspaces. Agents can plan, execute, and verify complex tasks across editor, terminal, and browser. Antigravity achieved 76.2% on SWE-bench Verified and supports Gemini 3 Pro, Deep Think, and Flash models, plus third-party models like Claude.
Autonomous spec-driven coding agent for complex long-horizon tasks. Runs a structured discovery loop and delivers production-ready PRs.
