Google Launches “Antigravity,” A New VS Code-Based IDE Powered by Gemini 3 Pro

Google has introduced a notable new entry into the developer tools space with the release of its Antigravity IDE.

Meet Google Antigravity, your new agentic development platform.

An evolution of the IDE, it’s built to help you:
– Orchestrate agents operating at a higher, task-oriented level
– Run parallel tasks with agents across workspaces

For anyone familiar with Visual Studio Code, the interface will feel immediately recognizable. The layout, panels and terminal remain largely the same. What stands out is a new control panel that allows users to activate multiple AI agents capable of handling complex tasks.

After signing in with a Google account and selecting a model such as Gemini 3 Pro, Claude Sonnet 4.5 or an open source alternative, these agents can plan features, generate tests, refactor code, launch terminals, open browsers for testing and even produce detailed artifacts such as screenshots or output logs. It shifts the relationship from “AI assisting the developer” to something closer to “AI taking the lead when needed.”

As a fork of Visual Studio Code, Antigravity’s long term compatibility with the extensive VS Code extension marketplace is uncertain. Running multiple agents can also require substantial computing power, so users may encounter performance issues unless they rely on strong local hardware or cloud compute. Accuracy and reliability remain concerns as well, since AI agents, even advanced ones, can still produce incorrect code or follow unexpected logic paths.

Antigravity is free to try for anyone with a Google account, though usage contributes toward Gemini model limits. It remains to be seen whether it becomes a widely adopted development environment or fades as a niche experimental project.

Platforms such as Cursor, Windsurf, Replit’s newer tools and GitHub Copilot Workspace are all pursuing similar concepts. While Google has significant resources, Antigravity will still need to demonstrate that it offers practical advantages in speed, quality and workflow integration.
