Google's AI agentic IDE: VS Code fork with autonomous multi-agent orchestration.
Best for
Antigravity is Google's AI-powered agentic IDE, announced November 18, 2025 alongside Gemini 3. A fork of VS Code, it features an Editor View for hands-on coding and a Manager Surface to orchestrate multiple AI agents that autonomously plan, execute, validate, and iterate on tasks.
It supports advanced models including Gemini 3.1 Pro, Gemini 3 Flash, Claude Sonnet 4.6, Claude Opus 4.6, and GPT-OSS-120B. Cross-platform on macOS, Windows, and Linux, it includes built-in MCP server support via MCP Store, terminal integration with configurable auto-execution, and a CLI tool (`agy`).
Pricing offers a free plan with unlimited tab completions and command requests, AI Pro at $20/mo, AI Ultra at $249.99/mo for high-volume access, plus AI credits ($25 for 2,500). Not open source.
