What it is

Barycenter is a Mac app for running a lot of AI coding assistants at the same time. Instead of one assistant in one window, you start a whole set of them, watch them work side by side, and jump in the moment one needs you. The assistants do the work. Barycenter is the control room where you keep an eye on all of them.

What it does

See every session at once in a grid, or zoom in on a single one
A session that needs you turns red and pings you, so you are not stuck watching the screen
Start new sessions from presets (Claude Code, Codex, Gemini CLI, Aider, or a plain shell) in any folder
Each session gets its own tabs: terminal, status, notes, a view of its changes, and a small file browser
A built-in manager that can start, watch and steer the other sessions for you
Shared notes and a to-do list across everything you have running

Built with
