Google Antigravity — Coding Agents Platform

What is Google Antigravity?
Google Antigravity is Google's agentic development platform, announced alongside Gemini 3 in late 2025. Built as a modified VS Code fork, Antigravity 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 environments. The platform achieved 76.2% on the SWE-bench Verified benchmark, demonstrating strong code generation capabilities. Antigravity supports Gemini 3 Pro, Deep Think, and Flash models, plus third-party models including Claude, making it flexible for developers who want to use different AI providers. Currently available in preview for personal Gmail accounts on Mac, Windows, and Linux, Antigravity is free during the preview phase but expected to introduce paid tiers. Google AI Pro subscribers ($20/month) and AI Ultra subscribers ($250/month) receive higher rate limits, with rate limits refreshing every 5 hours for Pro users.
Strengths and tradeoffs
