Free Mac app lets you run multiple Claude and Codex accounts at once
A free, open-source Mac app was released that lets you run multiple Claude and Codex accounts side by side in separate windows. No more logging in and out — each account stays open independently at the same time.
Normally, using more than one Claude or Codex account on the same computer means switching browser profiles or logging in and out repeatedly. This app solves that by keeping each account in its own isolated session, all running at the same time.
The project was shared on both r/ClaudeCode and r/OpenaiCodex, drawing interest from developers who juggle multiple AI tools or client projects. Being free and open-source means anyone can inspect or modify the code, which is a plus for those who care about what software is doing on their machine.
Key points
- Run multiple Claude and Codex accounts simultaneously on a Mac
- Each account gets its own window and stays logged in independently
- Completely free and open-source — source code is publicly available
- Useful for solo developers managing multiple projects or client accounts
