Choose Google Antigravity if you are developers who want to try the most agentic IDE experience available today. Choose Windsurf if you are developers who want an affordable AI editor with agentic capabilities.
Editorially this matchup is a dead heat: each agent leads in 3 of our six categories. On price, Google Antigravity runs free public preview and is proprietary; Windsurf runs free tier / $15-30/mo and is proprietary.
Antigravity is Google's agentic development platform, launched alongside Gemini 3: a VS Code-style IDE where an agent manager dispatches agents that work across the editor, terminal, and a Chrome browser they control — producing verifiable artifacts (plans, screenshots, browser recordings) as they go. The free public preview and Gemini 3 Pro quality made it an instant heavyweight, but it's still early: capacity limits, preview rough edges, and early prompt-injection concerns around the browser-control surface mean production teams should keep a human on the loop.
Windsurf (formerly Codeium) is an AI-first code editor featuring Cascade — an agentic flow that can handle multi-file, multi-step coding tasks. It combines the familiarity of VS Code with powerful AI capabilities including code generation, refactoring, and terminal integration.
