Munder Difflin

Agent harness to run an office of your clones

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.

⬇ Download 0.5.6 for macOS, Windows or Linux

macOS builds are signed and notarized. You do not need to build from source to use it. The open source build is on the GitHub releases page.

Cancel your Granola and Wispr Flow subscriptions. It dictates into any app and transcribes your meetings, all running locally.

New here? Start with the install guide, then your first hour, and see every agent on our own floor.

Launch offer: Pro is free for everyone until Saturday 24 October 2026: download the app and sign in. After that the Pro annual plan is $150 USD, adjusted for purchasing power in different countries and as low as $100 a year. Get Pro

[!NOTE] 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.

Supported agents

Bring the CLI you already pay for. Every one of these runs as a real process in its own terminal, with your existing subscription and its hourly limits. If it runs in a terminal, it can run here.

Plus bring your own keys and local models through Ollama, LM Studio or vLLM.

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 is 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.

1. You spawn agents: each is a normal terminal process (claude, agy, codex, or custom) with its own working directory, identity, and provider-specific lifecycle.
2. Agents collaborate through the hive: a local git repo of plain files. They write to their own outbox/; the harness's router delivers into recipients' inbox/. No agent ever touches git (single-committer design avoids index.lock corruption).
3. The GOD agent runs the floor: it reads every request, resolves routine ones itself (keeping the system fully autonomous), and only escalates critical items (spend, destructive ops, scope changes) into an approvals queue you act on.
4. Everything is visible: you watch avatars move, envelopes fly, and the live terminal stream; you can type back into any session, browse its files, and read its git history.

See HIVE.md for the full multi-agent design, SPEC.md for the terminal/event plane, and DESIGN.md for the visual system.
