Google Antigravity is a free agentic development platform that Google launched alongside Gemini 3 in November 2025. Its standout feature is that multiple AI agents can work on different tasks at the same time. The agents also open a Chrome browser themselves to click, type, take screenshots, and record video as they check their own results. For developers and automation users, the key point is that the verification step is handed to the agent too: it writes the code, runs through it in a real browser, and then hands over screenshots, recordings, and its execution plan for a human to review. What Is Antigravity: An Agent Management Platform Built Out of the IDE Antigravity is a desktop application for macOS, Windows, and Linux, and it is free for individual users during the public preview. It looks much like a typical code editor, but its design focus is different. Traditional AI coding assistants have you write code while the AI autocompletes. Antigravity has you assign tasks, watch the agents carry them out, and then review the results. For more on how Google positions it, see the official announcement on the Google Developers Blog . Antigravity's technology is linked to Windsurf. In July 2025, Google licensed technology from the AI code editor Windsurf and hired its core team, and this deal is widely seen as the origin of Antigravity. See the Wikipedia entry on Windsurf . The platform uses the Gemini 3 Pro model by default, and you can switch to Anthropic's Claude Sonnet 4.5 or OpenAI's open-weight model GPT-OSS. You can pick a model to suit each task instead of being locked into one. Two Work Views Editor view : A traditional editor interface with an agent chat panel in the sidebar. It suits writing code while asking the AI for help. Manager view : Officially described as the agents' "mission control." You can open several agents at once, each running tasks asynchronously in its own workspace or project. Multi-Agent Architecture: Parallel Work Instead of One Conv

Model Benchmarks: How Gemini 3 Pro Performs
Antigravity's agent capabilities depend mainly on the underlying model, and Gemini 3 Pro has clear published scores on agentic task benchmarks: Gemini 3 Pro scored 54.2% on Terminal-Bench 2.0, November 2025 (source: Google official blog) . This benchmark measures a model's ability to operate a computer through the terminal. Gemini 3 Pro scored 76.2% on SWE-bench Verified, November 2025 (source: Google official blog) . This benchmark evaluates a model's ability to fix real issues in GitHub projec
Free Plan Limits and Who It's For
Antigravity is free for personal Google accounts during the public preview, but it has usage limits. According to Google, the quota resets regularly, refilling about every 5 hours, so heavy users may hit the limit during intensive work sessions. For current plans and quotas, check the official Antigravity website and the official documentation . Terms may change after the preview ends. Good Fits Solo developers or small teams who want to move several feature branches forward at once. Frontend de
