Munder Difflin

Munder Difflin is a free, open-source desktop multi-agent harness that runs multiple terminal-based AI coding agents as coordinated local agents. It wraps agents including Claude Code, OpenAI Codex, Gemini CLI, Qwen, OpenCode, GitHub Copilot CLI, and custom commands, working with users' existing subscriptions and hourly usage limits. Each agent runs as a real node-pty process and is rendered through xterm.js, while an Electron and React interface displays sessions as avatars on a Pixi.js office floor. A GOD orchestrator called Michael assigns and routes work, adjudicates agent messages, and escalates spending, destructive operations, scope changes, and other configured approvals. Agents coordinate through a local Git-backed hive of plain-file memory, atomic mailboxes, a shared blackboard, and an append-only event log; a markdown-first semantic memory layer supports recall across sessions. Optional Git worktrees isolate parallel agents.

What Munder Difflin is used for

3 uses taken from transcripts — each links to the moment in the video.

  • A free, open-source multi-agent harness that turns CLI coding agents into digital clones that can work continuously. It orchestrates specialized agents to review pull requests, fix bugs, answer questions, and complete small tasks in isolated work trees.

  • An open-source Electron desktop app that organizes terminal coding agents into a coordinated multi-agent office. It gives agents pseudo-terminals, memory, mailboxes, an orchestrator, and a Git-backed filesystem for parallel coding work.

  • A local-first open-source desktop application that runs an office of coordinating AI agents. It turns command-line AI tools into a self-coordinating team with long-term memory, mailboxes, desks, and a visual 2D office.
