Free, open source and performant — a multi-agent harness that works with the subscriptions you already pay for, on their hourly limits. It turns the terminal coding CLI you already run into a clone of you, one that keeps working while you're away and coordinates a whole office of agents on your own machine.
Wraps Claude Code, Antigravity (Gemini), OpenAI Codex, xAI Grok, Kimi Code, Gemini CLI, Qwen, OpenCode, Crush, pi.dev, GitHub Copilot CLI, and Cursor — with bring-your-own keys and local LLMs. Agents that message, route, and remember, coordinated by your clone (Michael) and visualized as avatars at work on a shared office floor.
The world's best agents. The world's worst paper company. Munder Difflin takes the terminal-agent CLIs you already run — claude, agy, codex, grok, kimi, qwen, opencode, crush, pi, and copilot — and turns them into a self-coordinating team: each agent gets long-term memory, a mailbox, and a desk on a 2D office floor — and your clone (Michael) routes work between them while you watch. He's the boss of the floor; you're still the boss of him.
What it is
Munder Difflin is a desktop app that wraps real terminal-agent CLIs as fully-capable agents, wires them into a hive mind, and puts your clone in charge — Michael, the one agent you talk to in order to get things done. Under the hood it runs the fastest memory layer in the world so every agent remembers what it learns and recalls it instantly.
- Every terminal is an agent. Each claude, agy, codex, grok, kimi, qwen, opencode, crush, pi, copilot, or custom session runs as a real process in a pseudo-terminal (node-pty), byte-for-byte authentic, rendered with xterm.js.
- Every agent is an avatar. Sessions appear as characters on a Pixi.js office floor — they walk to stations as they work, and envelopes fly desk-to-desk when they message each other.
- The hive coordinates them. Agents read their memory and drain a mailbox; the router moves messages between inboxes; the GOD agent adjudicates, assigns, and escalates only when it needs you.
- Memory that's instant. A markdown-first memory layer with a semantic recall index means agents remember across sessions and recall in milliseconds.
