Google Antigravity
Google's free agentic IDE — Gemini 3 built in, 76% SWE-bench score
About
Google Antigravity is an agent-first IDE launched in November 2025 alongside Gemini 3. Unlike Cursor or VS Code, Antigravity is built around a Manager View that lets you run multiple AI agents in parallel across workspaces — delegating tasks asynchronously while you focus elsewhere. It scored 76.2% on SWE-bench Verified, placing it among the highest-performing coding agents publicly benchmarked. The entire platform is free, with Gemini 3 Pro, Claude Sonnet 4.5, and GPT-OSS all included at no cost. Adopted by 6% of professional developers within two months of launch.
