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.

[!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.

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.

Features

<table> <tr> <td width="50%" valign="middle">

Cancel your Granola and Wispr Flow subscriptions

Dictate into any app. Hold Option on the Mac, or Control+Alt+Space on Windows and Linux (X11), talk, and let go. The words land in whatever field is in front of you, and in every text box inside Munder Difflin. The message box mic works in the free build too.

Meetings hear both sides, in Stapler, part of Pro. Your microphone is written as You and the call's audio as Them, on Mac, Windows and Linux. Shift+Command+Space starts and stops a meeting on the Mac, Control+Shift+Space on Windows and Linux. Correct the transcript, add a description, and send it to any of your agents.

Transcription on your machine. A Whisper model ships inside the app and is the default engine. A larger model is one download away, Apple's on device recogniser works on macOS 26, and Groq stays off unless you add a key. 126 built in technical names plus your own words. English for now.

One row per agent, and it tells you everything

Classic, the free skin, gets the new agent cards: status, engine, model, a context gauge, the ticket it is on and the action it is taking right now, a crash strip instead of a silent terminal, and a right click menu for the common jobs.

Pro gets the new sidebar: Tasks, Inbox, Automations, Memory, Capabilities and the Stapler at the top, agents grouped under their projects, a live line per agent, Asked you on the row when an agent has a question, notes you can search, and Keep my agent order to drag agents and projects where you want them. Drag the sidebar's edge to make it wider, hover a ticket for its details, or switch to agents and notes only.

</td> </tr> <tr> <td width="50%" valign="middle">

Talk to one agent, not twelve

Michael is your clone and the only agent you brief. He assigns the work, routes the traffic, and escalates the few things that actually need you.
