Munder Difflin

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.

How it works

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.

Features

The floor

- Every terminal is a real agent. Claude Code, Antigravity (Gemini), OpenAI Codex, xAI Grok, Kimi Code, Gemini CLI, Qwen, OpenCode, Crush, pi.dev, GitHub Copilot CLI, Cursor, or a custom command — each in its own node-pty PTY, rendered with xterm.js.

- Every agent is an avatar. A Pixi.js office floor where agents walk to stations, envelopes fly desk to desk, and avatar state reflects real work.

- A GOD orchestrator you talk to. It routes tasks, adjudicates traffic, and escalates only what needs a human. Or press Talk and run the floor by voice.

- Per-agent git worktrees. Optional isolation so parallel agents never collide on branches.

Memory & coordination

- The hive — per-agent memory, atomic-file mailboxes, a shared blackboard, an append-only event log, single-committer git.

- Semantic recall — markdown memory mined into a shared palace, searchable from the UI, with condensation so it doesn't grow forever.

- Enterprise Knowledge Graph — your own documents and policies, queryable by any agent.

Control & safety

- Human gates — spend, scope, and destructive ops escalate to you. Steer mid-run or stop gracefully.

- Circuit breaker — a steer → constrain → stop ladder for agents that loop, storm errors, or blow their budget.

- Budgets & telemetry — per-agent token budgets, real cost from transcripts, a durable ledger, OTel spans, and a tool waterfall.

Command Center

- Kanban tasks with dependencies, scheduled missions + heartbeat, live fleet monitoring, memory search, activity log, and a CI watcher.

- Skills — what every agent can already do across Claude Code, OpenCode and Codex, plus a browsable catalog of 227 more with search, filters, install and uninstall.

- Built-in Monaco IDE — file tree, editor tabs, save, plus CHANGES · HISTORY · COMPARE git rails with commit graph, diffs, branch compare, and guarded checkout. All fs/git access brokered through main.

Getting work in and out

- Slack & webhooks — message a channel or POST a webhook; Michael can spawn an ephemeral worker, reply in-thread, and tear it down.

- Shareable hires + Agent Gallery — import a role from a munderdifflin://hire link; import only pre-fills the form, a human still spawns it. Browse roles at the Agent Gallery.

- BYOK keys + local LLMs — per-provider keys in a write-only secret broker, plus Ollama / LM Studio / vLLM base URLs. Guides: open models · Mac Mini.

- Updates in one click: the title-bar badge runs the real update. It downloads the build for your machine, then restarts and installs it, and it reads latest once a check confirms you are current. A manual download is the fallback for when the updater cannot fetch the build itself. The first run afterwards opens that release's notes as a designed page rather than a version number.

- Your language: English, Simplified Chinese and Arabic, with right to left layout for Arabic. English is the default and nothing changes until you pick another one in Settings. The app does not read your OS locale. All three app fonts ship inside the bundle, so nothing is fetched at boot.

- Prerequisites — one Settings page showing which supporting tools (uv, git, Node, MemPalace, each agent CLI) you have, what each is for, and a button that asks Michael to install what is missing.
