Community Project Disclaimer

Antimatter is an unofficial, community-driven, open-source project. It is NOT an official product of Google, nor is it officially affiliated with the Google AntiGravity IDE project.

Antigravity 2.0 Support

Antimatter now natively supports the standalone Antigravity 2.0 desktop application! You can use our dual-bridge architecture to connect to both the classic IDE and the new 2.0 orchestrator seamlessly.

Why Antimatter?

Developing with autonomous AI agents often means leaving them running for long periods. Antimatter ensures you aren't chained to your desk — monitor, control, and interact with your agent from anywhere using your phone, secured by enterprise-grade cryptography.
