Google Antigravity vs Sourcegraph Cody: Coding Agents Comparison

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.

Sourcegraph Cody is an AI coding assistant that provides intelligent code completion, chat, and custom prompts within popular IDEs. The free plan offers unlimited autocompletion with 200 chats/prompts monthly. Cody Pro at USD 9/month provides unlimited autocompletion and increased chat limits. Enterprise at USD 59/user/month adds SSO, BYOK, and custom deployment. Important note: Cody Pro and Free will not be available for new signups starting June 25, 2025, with existing users losing access July 23, 2025. Sourcegraph is transitioning to Amp, their next-generation AI coding platform, though Enterprise customers remain unaffected by these changes.
