Google has introduced the Antigravity platform, which it calls «a new era in software development using artificial intelligence.»
Antigravity is currently available for free download by individuals and is compatible with MacOS, Linux, and Windows.
Also, within the agent, there is a choice of three models: Google Gemini 3, Anthropic Claude Sonnet 4.5, and OpenAI GPT-OSS.
Google Antigravity has browser control capabilities, asynchronous interaction patterns, and «enables agents to autonomously plan and execute complex, integrated software tasks.»
«We want Antigravity to become the foundation for software development in the agent era. Our vision is to ultimately empower anyone with an idea to test it and make it a reality,» Google said in a blog post.

They add that the main «editor» of Antigravity is a modern IDE interface based on artificial intelligence, with auto-completion using Tab, built-in commands, and a full-featured agent in the sidebar.
