Add MulmoTerminal — browser terminal grid for running multiple Claude Code / Codex sessions #551

Description

@isamu

Hi — suggesting a resource for the list. Contribution Guidelines say "Under Construction", so opening an issue rather than a PR. Happy to send a PR instead if you prefer.

Repo: https://github.com/receptron/mulmoterminal
License: MIT

Suggested entry (matching the existing format):

- [**mulmoterminal**](https://github.com/receptron/mulmoterminal) - Browser terminal that runs multiple Claude Code and Codex sessions in a grid, colour-coded by which agent needs input, with tmux persistence, git worktree isolation and phone push.

Suggested section: 🖥️ Clients & GUIs, or 🤖 Agents & Orchestration if you consider multi-session supervision to belong there.

What it does

Each cell is a real PTY running the claude or codex CLI on your own machine, streamed to xterm.js over a WebSocket. The grid colour-codes every session by state — working, blocked on input, done — so the one that needs you is visible without visiting each pane. Sessions survive a reload through tmux, parallel work isolates in git worktrees with one-click PRs, and a finished or blocked turn can send a Web Push to your phone.

Nothing runs in the cloud: your code, your keys, your existing CLI. One command, no install:

npx mulmoterminal@latest
