ADE puts Claude Code, Codex, Cursor, Factory Droid, and OpenCode in one app. You use the plans you already pay for.
It runs on your own machines. Sign in on each one, and you can reach all of them from the desktop app, the terminal, the web, or your phone. Every chat and terminal session stays in sync. I start a task on my desktop at home, check on it from my phone at the gym, and finish it in a browser on a friend's laptop.
It's also a full dev environment: git worktrees, a code editor, pull requests, and history. And it's free.
