English · 日本語 · 简体中文 · 繁體中文 · 한국어

Run multiple coding-agent sessions in parallel — and see which one needs you.

A browser terminal for parallel AI coding agents: several sessions side by side, each in
its own cell, with the one that needs you marked in colour. Claude Code is the default and six
more CLIs are first-class — Codex, Antigravity, Grok, Muse, GitHub Copilot CLI and Cursor CLI. Vibe
coding with a single agent needs nothing but a shell — this is for when you run several and lose
track of which is waiting. Sessions survive a reload (tmux), work isolates in git worktrees,
and a phone push reaches you when a turn finishes.

Every cell is a real pty. htop, lazygit, a dev server and Claude Code are the same kind
of object here — which is why the one-session-per-worktree limit applies to agents only, and
a shell or a yarn dev launcher can sit in the same worktree an agent is working in.

Demo

*The grid, live — each cell coloured working, done or needs you.*

*90 seconds, with sound: one agent, then a grid of them. Zoom into one and the roster still holds what every other session asked, answered and did, so you go to whichever is lit and lose nothing catching up.*

Transcript of the narration

When you ran one coding agent, the slowest thing in the room was the agent.

Now that you run five, the slowest thing in the room is probably you.

One of them is always stopped. A permission prompt. A question. Until you notice, it does nothing at all.

MulmoTerminal puts every session on one screen. Blue is working. Green is done. Amber is waiting on you.

You stop hunting. You go where the light is.

The other kind of slow is: what did I even ask this one? The roster keeps one…
