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.
Replit Agent is an AI coding assistant built into Replit's cloud IDE that can build entire applications from natural language descriptions. It handles project setup, code generation, package installation, and deployment in Replit's cloud environment. Replit Agent makes software creation accessible to non-programmers while providing useful automation for experienced developers.
