Google launches Antigravity, a new AI-powered IDE for autonomous agentic coding

Every few months, it feels like the bar for AI coding tools gets raised. And now, as part of the Gemini 3 update, Google is attempting to raise it yet again with the launch of Antigravity, a new “agentic development platform” designed to change how developers interact with AI. While today’s tools like Copilot or Gemini Code Assist act as helpful chatbots in your sidebar, Antigravity envisions a world where the AI isn’t just an assistant—it’s an autonomous developer working alongside you.

More than just a chatbot

At its core, Antigravity appears to be a robust fork of Microsoft’s open-source VS Code, which is great news for familiarity and extension support. But the “agentic” part is where things get interesting. In Antigravity, AI agents are given dedicated access to three critical tools: the Code Editor, the Terminal, and the Browser.

This trifecta allows the agent to do something unprecedented: autonomously plan, execute, and validate its own work. You can ask an agent to build a new feature, and it can write the code, use the terminal to launch a local server, and then—crucially—activate a real Chrome browser instance to test that the feature actually works.

Seeing is believing (and debugging)

One of the standout features is how the agent communicates its progress. Instead of just spitting out code, Antigravity agents produce “Artifacts” like task lists, implementation plans, and even screen recordings. Because the agent can see and control the browser, it can record a video of itself testing the app, proving that the code it wrote actually functions as intended.

Users can then provide feedback directly on these artifacts—commenting on a screenshot or a specific part of a plan—much like you would in Google Docs. This creates a feedback loop that feels less like prompting a bot and more like code-reviewing a junior developer.

Antigravity also introduces a “Manager” surface, a dedicated dashboard for spawning and orchestrating multiple agents across different workspaces. Theoretically, you could have one agent fixing a bug in your backend while another prototypes a new frontend feature in a separate workspace, all monitored from a single mission control center.

Available for Mac, Windows, and Linux

Google Antigravity is available in public preview starting today at no charge for individuals. The best news for developers is that it’s truly cross-platform out of the gate. You can download and install it right now on macOS, Windows, and Linux.
