Munder Difflin

Munder Difflin is a free, open source desktop harness that runs Claude Code, Codex, Gemini CLI and nine other terminal agents as a team under one orchestrator, locally and on your existing subscriptions.

Munder Difflin is a free, open source harness that turns the terminal coding agents a developer already uses into a coordinated team. Instead of juggling separate tabs for Claude Code, Codex, Gemini CLI, Copilot, Cursor and others, it runs each one as a "clone" in a real terminal and puts them on a shared floor. Twelve providers are supported, and the model pickers read their lists at launch, so new models appear without waiting for an app update. The workflow centres on an orchestrator named Michael. A user gives him one sentence, and he splits it into tasks, assigns each to a suitable clone and lets them hand work to each other. Every clone can read a shared task board, has its own inbox, and questions that need a person are collected in a single Ask me box. A circuit breaker is meant to stop runaway spend, and crashed agents restart in the same folder with their work intact. Each clone also keeps memory of what it learned and who worked on what, so the office can answer questions about its own history, stored locally. Everything runs on the laptop and drives the CLI agents under existing subscriptions, so the plan's own hourly limits do the work. Code, keys and personal context stay on the machine. When clones on different machines communicate, messages are signed and sealed on the sender's side. Multiple projects can run at once as separate "floors", each with its own agents, board and memory. The free Classic edition shows a pixel-art office with unlimited local agents. Pro replaces it with a sidebar workspace and adds the Stapler, a floating window for local dictation, meeting transcription and screenshots handed to agents. Teams adds cross-machine orchestrators and an admin console. Compared with running a single agent CLI or a cloud-hosted agent service, it targets developers who already pay for several agent subscriptions and want one local layer to coordinate them. Remote control and hosted sandboxes are listed as coming, and the machine must stay on for clones to keep working.
