Eaon vs Google Antigravity
Eaon and Google Antigravity
Antigravity runs Google's agent. Eaon runs Antigravity's CLI next to Claude Code, Codex and OpenCode, in one window.
In short
Google Antigravity is Google's agent platform: an agent-manager app, an IDE, a CLI and an SDK, with a generous free tier that includes Gemini and Claude models, a browser agent that drives Chrome, automations, voice input and remote control from a browser. It runs Google's own agent.
Eaon's ADE can run Antigravity's CLI in one pane and Claude Code, Codex or OpenCode in the next, each on its own branch. Eaon is open source and free, with no plan to upgrade to, and adds local models, pull request review, Linear issues and an everyday AI chat.

Questions
Can I use Google Antigravity and Eaon together?
Yes. Both work on git worktrees in your own repositories, so you can try Eaon on one project and keep Google Antigravity on another.
Is Eaon really free?
Yes. Eaon is free and open source under GPL-3.0, with no account and no subscription. You pay your model providers directly, or nothing at all with local models.
