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.
Electron · React · TypeScript · Pixi.js · xterm.js · node-pty

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.

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.
Claude Code Codex · GPT Grok · xAI Kimi Code Gemini CLI Antigravity · Gemini Qwen OpenCode Crush · Charm Pi GitHub Copilot Cursor + any custom command
Plus bring your own keys and local models through Ollama, LM Studio or vLLM.
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.

- You spawn agents: each is a normal terminal process (
claude,agy,codex, or custom) with its own working directory, identity, and provider-specific lifecycle. - 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 avoidsindex.lockcorruption). - 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.
- 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.

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. 
|
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. |
|
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. |
|
|
Pick the CLI, the model and the autonomy, give it a desk, and it starts working. Import a ready made role from the Agent Gallery if you would rather not start from scratch. |
|
|
Every agent keeps markdown memory that is mined into a shared, searchable palace. Close the app, come back tomorrow, and they still know what they learned. |
|
|
Set how far each agent may go on its own. Spend, scope and destructive operations come back to you, and a circuit breaker steers, constrains, then stops anything that loops or runs away. |
|
|
Agents walk to stations as they work and envelopes fly desk to desk when they message each other. Click any desk to read that terminal live, and type straight back into it. |
|
|
The onboarding wizard checks what you already have, and offers to install what is missing rather than sending you to a docs page. |

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-ptyPTY, 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.
- More than one floor (0.5.3). File, New Floor opens another office on its own folder, in its own window, with its own agents, board and memory. A folder only ever opens in one floor, and one licence covers them all.
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
- Tickets with keys (0.5.3): every card gets a key like V53-299, each agent has a Tasks tab with what it did and when, and the Tasks screen filters by date.
- 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://hirelink; import only pre-fills the form, a human still spawns it. Browse roles at the Agent Gallery. - Local transcription and dictation (0.5.3): dictate into any app (Option on the Mac, Control+Alt+Space on Windows and Linux X11), and Stapler in Pro transcribes meetings with You and Them on Mac, Windows and Linux. A bundled Whisper model is the default engine; Apple's on device recogniser on macOS 26 and Groq with your own key are options. A built in vocabulary of 126 technical names keeps Anthropic, Claude, Kubernetes and ARR spelled right, and you can add your own.
- Tell an agent from the Stapler (Pro): Record message, several screenshots per message, PDFs, videos and folders, and a To menu that remembers who you picked.
- 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
latestonce 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.
Note
Status: v0.5.6. Capabilities, Integrations and Teams, and fewer tokens.
Pro is free for everyone until Saturday 24 October 2026, as part of the launch: download the app and sign in.
These notes describe the 0.5.6 app on the download page.
Capabilities (Pro): a marketplace of 2,347 MCP servers, skills, plugins and tools from the public list
HarnessMD/awesome-agent-capabilities. We reviewed 622 of
them; the rest read "Listed, not reviewed by us" and have no Install button. A merged change reaches the app with no
new release, and the app uses the list only when it carries our signature.
Integrations: one place for Slack, webhooks, the apps your agents use and your keys, each with a plain status and
the last 50 things that happened. Nothing saves until you press Save.
Teams: your office talks to your teammates' offices. One plain chat per teammate, you choose who answers each one,
and files and folders go as a link with a password, for one download.
Fewer tokens by default: Compact when context fills and Clear on a switch of work are on for every new install.
The clear runs when an agent's work switches after a session of 60 minutes, and a handoff.md in the agent's folder
carries the thread across. A new install has no hourly standup. In a replay of one office of 13 Claude agents over a
week, with those two changes, token use fell about 37%. That is a replay, not a live measurement.
Agent files (Pro): export an agent as a file and choose what goes in; a key, a token or a secret's value never
does. 36 templates replace role bundles.
Temps: any lasting agent can start a temp, a short lived agent for one job, not only the orchestrator. Wherever you
pick who answers (Slack, a teammate, a webhook, a schedule's Sends to, the Stapler's Send captures to), you can pick
A temp or A temp, clone of one of your agents. Temps per agent (0 to 4) and Max temps at once sit on
the orchestrator's Budget & breaker tab.
Slack: one bot answers in All channels it is in by default, or only the channels you tick, and in direct
messages; replies stay in the thread. Set the Slack app up from the manifest: press Copy manifest under
How to get these. Slack comes back by itself after a failed start.
Token limits per period: Every 5 hours, Daily, Weekly or Monthly, for the office and for each agent. They replace
the old token caps.
Sign in and accounts in the app: press Open browser to sign in and sign in there; the screen moves on by itself,
or you paste the code into Code from the browser. Sign out and Switch to Teams sit in the profile menu.
Circuit breaker: an agent that stopped as told is no longer constrained again, and the same warning is not sent twice
inside ten minutes.
Fixes: the window no longer hangs after hours, hooks work in Claude Code's auto mode, sign in works on a network with
its own certificate, a message to Codex no longer waits for Enter, the Windows folder name field shows the name and not
the whole path, the Dock click works the first time with the Stapler on, and Haiku 5.5 is in the model list.
New to it? The install guide and your first hour cover every step.
v0.5.3: Cancel your Granola and Wispr Flow subscriptions. The Stapler does both, all running locally, and every agent gets easier to start, restart and steer. Dictate into any app: hold Option on the Mac (Microphone and Accessibility permissions), or Control+Alt+Space on Windows and Linux X11, talk, and let go. Wayland says why it cannot. Meetings hear both sides in Stapler, part of Pro: You and Them, on Mac, Windows and Linux, transcribed locally, then corrected, described and sent to any of your agents. Transcription on your machine: a bundled Whisper model by default, an optional 190 MB larger model, Apple's on device recogniser on macOS 26, and Groq only if you add a key. 0.5.3 transcribes English. The bundled model is English only; on macOS 26 dictation runs on Apple's engine, which follows the Mac's language and we have tested it in English. Other languages arrive as a model download in a later release. A missing CLI is a card, not an error: install and sign in from inside the app for every engine, with Set up manually when either fails. Ask me on every agent's Inbox, answered from one box over the composer. More than one floor: File, New Floor (Shift+Command+N, or Control+Shift+N) runs another office on its own folder, with its own agents, board and memory, and one licence covers every floor. Send now goes straight in, Restart & Continue keeps the conversation for every engine, and Opus 5.5 is the default Claude model. Settings, redesigned: one Save for everything, inbound webhooks for GitHub, Linear, Telegram and your own, each with the agent that answers it, and custom secrets stored encrypted beside your provider keys. Crashes keep your work: a crashed agent keeps its uncommitted work. The IDE opens on Command+I with find and replace, the sidebar's reorder handle sits on the right in Arabic, and code in the IDE reads left to right in every language. Automatic compaction runs every 40 minutes at 30 percent of the context window, the same bar on every model size, where the previous default was every two hours at 60 percent. Tasks you can follow: every ticket gets a three letter key like V53-299, taken from the hive folder's name or set in Settings, Autonomy. Each agent has a Tasks tab beside Inbox and Terminal with what it did and when, the Tasks screen filters by Today, This week, This month or All time, and a card drops anywhere in a column. Hover a ticket in the sidebar for its details. The Pro sidebar is as wide as you drag it, and one setting shows only agents and notes. With more than one floor open, each window and Dock icon carries the office's number. Stapler fixes: the mic stops at the click, no words are lost at a pause, Record message never gets stuck, the drag follows your pointer, Reset puts it in the middle of the screen, and it never ends up off screen. Fixes: a restarted agent's terminal takes the mouse again, the hive repository no longer swallows agent git folders into its object database and the disk space comes back, and one hook event now renders one sidebar row with the task ledger read once. Not in this release: the Kimi scroll and queue bug, which we could not reproduce, and it is first on the 0.5.4 list. Before that, v0.4.6 brought a Simplified Chinese and Arabic interface with right to left support and self hosted fonts, the update badge that runs the real download and restart, and the security work on CLI name validation and analytics. If you're on 0.3.8, update: that build's usage-limit guard never released the agents it held, and it has been removed entirely. macOS (signed & notarized), Windows, and Linux builds are on the download page. The open source build is on the releases page.
Most people want this one. Munder Difflin is free and open source. Signed and notarized macOS builds of 0.5.6, plus Windows and Linux, are on the download page. The open source build is on the GitHub releases page. Install it, open it, and the wizard takes you the rest of the way. The install guide walks through every step and every fix. You do not need Node, a toolchain, or this repository.
You do still need at least one agent CLI on your machine. From 0.5.3 a missing CLI shows as a card in the agent's terminal: Install runs the command, you sign in inside the app, and the agent starts. Settings → Prerequisites lists the rest.
Pro adds Capabilities, agent files, Stapler and the new sidebar. As part of the launch it is free for everyone until Saturday 24 October 2026. After that the annual plan is $150 USD, adjusted for purchasing power, as low as $100 a year. Get Pro
Everything below is for contributors and for people who want to run an unreleased build.
- macOS, Windows, or Linux.
- Node.js 18+ and npm.
- A C/C++ toolchain for
node-pty's native addon. On macOS, install Xcode Command Line Tools:xcode-select --install
- At least one supported agent CLI on your
PATH, one of Claude Code (claude, the default), Antigravity (agy), OpenAI Codex (codex), xAI Grok (grok), Kimi Code (kimi), Gemini CLI (gemini), Qwen (qwen), OpenCode (opencode), Crush (crush), pi.dev (pi), GitHub Copilot (copilot), or Cursor (cursor-agent). Most missing CLIs self-heal: the harness runs the installer in the terminal and continues into the new binary. - Optional: your own API keys and local LLMs in Settings → AI Engines (Ollama / LM Studio / vLLM).
- Optional: the semantic memory index for instant cross-session recall. Markdown memory works without it.
