Google Antigravity, launched in November 2025 alongside the Gemini 3 model, extends agentic coding past the editor and terminal into the browser as well, letting an agent plan, execute, and verify a task across all three surfaces in one session rather than being confined to code files alone.
Built on a VS Code foundation, it includes both a familiar synchronous editing view with tab completion for hands-on work and an agent-first interface for delegating larger tasks. Model choice extends beyond Google's own models, with support for Gemini 3 Pro, Anthropic's Claude Sonnet 4.5, and OpenAI's GPT-OSS available in the same platform.
Antigravity is free for individuals during its public preview. For a developer who wants an agent capable of acting across code, terminal, and browser together, rather than one confined to files alone, Antigravity's cross-surface scope is a distinctive design choice among Google's several coding tools in this category.
