I built atria, a terminal UI for managing multiple agent sessions in one place. It works as an "agent multiplexer" for sessions running on your own machine.

If you're thinking "why not just use tmux?": It works fine alongside tmux and gives you extra status, visibility, and quick control over agent sessions.

There's three ways to use it:

- Standalone with embedded terminal multiplexer (works in any terminal).

- Integrated with tmux (which still lets you launched into embedded if you want).

- "magic" integration with a few terminals: iTerm2, kitty, and WezTerm.

Supports Claude Code, Codex, OpenCode, and Copilot.
