Why you'd want it
Munder Difflin is an Electron desktop app that wraps terminal agent CLIs such as Claude Code and Codex, each running as a real process in its own pseudo-terminal. You brief one orchestrator agent, which the README calls Michael or the GOD agent, and it assigns work and routes messages between agents through mailboxes in a shared hive of plain files. Spend, scope and destructive operations are escalated to an approvals queue for you, and the README says each agent has configurable autonomy and a circuit breaker for loops. Agents keep markdown memory with an optional semantic recall index, and per-agent git worktrees are available as optional isolation. It uses the subscriptions you already have for the CLIs, with bring-your-own keys and local models as options.
Best for
- Running several Claude Code and Codex agents in parallel
- Briefing one orchestrator instead of many agents
- Watching and steering agent terminals from one window
Use it when
You already use agent CLIs such as Claude Code or Codex and want several running on your own machine, coordinated by one orchestrator agent with human approval for spend and destructive operations.
Skip it if
The README calls it pre-release software, and it is an Electron desktop app that needs at least one agent CLI already installed, not a library or a headless tool. It runs real agent CLIs as processes you configure the autonomy of, stores provider keys and custom secrets, accepts inbound webhooks, and its dictation feature asks for Microphone and Accessibility permissions on macOS, so review the autonomy and permission settings before use. Official builds send anonymous usage events (opt out in Settings, with DO_NOT_TRACK, or by building from source), and the Pro tier with the Stapler and new sidebar is paid.
Editor's note
The README says most people should use the prebuilt macOS, Windows or Linux app from its download page; the snippet above is the build-from-source route. The README links use the chaitanyagiri owner while the repo resolves to HarnessMD/munder-difflin. Source code is MIT; the bundled pixel art is licensed separately.
