Google Antigravity is an AI-powered integrated development environment (IDE) developed by Google, designed for prioritizing AI agents platform for software development. Announced on November 18, 2025 alongside the release of Gemini 3, Antigravity enables developers to delegate complex coding tasks to autonomous AI agents powered primarily by Google's Gemini 3.1 Pro and Gemini 3 Flash models. The platform is a heavily modified fork of Visual Studio Code. There is debate as to whether it is a direct fork of the software, or whether it is a fork of Windsurf, another AI-oriented code editor which is itself a fork of Visual Studio Code. Google Antigravity supports multiple AI models, including Anthropic's Claude Sonnet 4.6 and Claude Opus 4.6, as well as an open-source variant of OpenAI models (GPT-OSS-120B).
Antigravity was released in public preview on the day of its announcement and is available free of charge for Microsoft Windows, macOS, and Linux, with "generous rate limits" for Gemini 3.1 Pro usage.
