Munder Difflin v0.4.1

A local hive of Claude Code, Antigravity, Codex, Grok & Copilot agents that run themselves — messaging,
routing, and remembering, coordinated by your clone, Michael, who you talk to. Local-first and open source.

What's new in 0.4.1 — The app says what the site says

Michael is your clone. The website has been describing Munder Difflin as a clone of you that
works around the clock — the app still called it a "GOD agent." Now they match.

  • Your clone, not the GOD agent. Michael is described as your clone throughout onboarding,
    and his card on the floor carries a BOSS tag — he's the boss of the agents, you're still
    the boss of him.
  • Onboarding was rewritten. It opens on what you actually get ("a clone of you, working
    24/7") instead of a feature list, and the engine card no longer advertises three engines when
    ten ship — Claude Code, Codex, Grok, Kimi, Antigravity, Qwen, OpenCode, Crush, pi and Copilot
    are all named.

Note

This release changes wording only. The god agent id, the hive folder layout, and message
routing are untouched, so existing hives, memory, and running agents carry over exactly as they
are. Nothing to migrate.

Still new in 0.4.0 — The brand grew up

Munder Difflin looks like one product now. The dock icon, the in-app logo, the site favicon,
and munderdiffl.in all carry the same yellow "MD" mark — and the landing page was rebuilt to show
the real app instead of describing it.

  • New app icon on every platform. macOS gets a proper margined-and-shadowed .icns, Windows a
    full-bleed .ico, Linux a 1024px .png — all cut from the same yellow tile as the in-app logo.
  • The landing page shows the product. A looping screen recording in the hero, real screenshots
    of the Add Agent dialog, the memory panel, and Autonomy & Budgets, and a live pixel-floor sim in
    a yellow Pokédex shell.
  • Bright by default. The site now opens in light mode; dark is one click away and remembered.
  • Pricing, reframed. Two services carry the Teams story: Private Cloud (a dedicated
    sandbox VM per clone, 24/7) and Private Network (E2E-encrypted clone-to-clone wire).

Still new in 0.3.9 — Ask the app whether it's up to date

Settings → General now answers the question directly. It names the version you're running,
tells you whether that's the latest, and gives you one button that says what pressing it does:
Check for updates → Download v0.4.0 → Restart to update. The toolbar chip beside the
logo has always carried this, but it goes blank when everything is fine — which is not somewhere
you go to ask.

  • The avatars in the fullscreen roster are bigger. They were drawn at 1× — an 18-pixel figure,
    too small to tell two hires apart at a glance, which is the tile's whole job.

Important

If you are on 0.3.8, update. That build shipped a usage-limit guard that never let go: agents
held behind a limit stayed held, the reset never landed, and resume now dropped them straight
back into the hold. The guard is removed entirely — 0.3.9 delivers messages the way 0.3.7 did.

Note

Auto-update carries you here from v0.3.7 or v0.3.8. If you are still on v0.3.5 or v0.3.6,
those builds shipped the broken updater and need one manual install — grab the download below,
once.

Previously

  • 0.3.8 — memory condensation works for the first time; a Triggers hub; one compaction
    schedule instead of two; a readable commit history.
  • 0.3.7 — auto-update actually runs: a CommonJS/ESM import bug meant the native updater never
    fired in any packaged build since v0.3.4, and the failure was swallowed by a catch.
  • 0.3.6 — a machine with nothing on it can run agents: Node and npm install themselves
    (verified against the official SHASUMS256.txt), hooks stopped dying with exit 127, ~/dev/foo
    paths resolve, and the office floor rebuilds itself after losing its GPU context.
  • 0.3.5 — a send now escape hatch for a paused message queue, and a compact Command
    Center header.
  • 0.3.4 — talk mode that knows the floor, markdown previews, the IDE git time-machine
    (history + branch compare), redesigned Settings, xAI Grok and Kimi Code, and a single
    delivery gate for every automatic writer. Community work by
    @gts-47 and @qschmick.
  • 0.3.3 — the built-in Monaco IDE, and GitHub Copilot CLI as the first community-contributed
    engine (@anxkhn).
  • 0.3.2 — Realtime Michael: a voice channel to the GOD orchestrator.
  • 0.3.1 — three more engines: OpenCode, Crush, and pi.dev.

⤓ Downloads

Latest builds for every platform. The macOS build is universal — one DMG that runs on both
Apple Silicon and Intel.

🍎 macOS

Build File
Universal (Apple Silicon + Intel) Munder-Difflin-0.4.1-mac-universal.dmg

🪟 Windows

Build File
Installer (x64) — recommended Munder-Difflin-0.4.1-win-x64-setup.exe
Portable (x64, no install) Munder-Difflin-0.4.1-win-x64-portable.exe

🐧 Linux

Build File
AppImage (x86_64) Munder-Difflin-0.4.1-linux-x86_64.AppImage

📦 Source

Source code (zip) ·
Source code (tar.gz)

Verify your download: SHA256SUMS.txt — then shasum -a 256 -c SHA256SUMS.txt (macOS/Linux) or Get-FileHash (Windows).

The filenames above carry a version number, so they only resolve while this is the
latest release. If a link 404s you are reading an old release page — grab the current
build from the releases page,
which is always right.

First launch

  • macOS — the build is signed with a Developer ID (hardened runtime). If macOS
    still shows an "unidentified developer" warning on first open, right-click the app →
    Open → Open once. After that, the first time agents touch a folder you'll get a
    single macOS privacy prompt for Documents/Desktop/Downloads — allow it once and the
    grant sticks (it covers the claude agents the app spawns), because the grant is bound
    to the app's stable signature.
  • Windows — not code-signed yet; SmartScreen may show "Windows protected your PC" →
    More info → Run anyway.
  • Linux — make the AppImage executable: chmod +x Munder-Difflin-*.AppImage, then run it.

Requirements

  • macOS 12+, Windows 10/11, or a modern Linux desktop
  • Claude Code installed and on your PATH (and/or the Antigravity agy or OpenAI codex CLI for those providers)
  • A Claude Code subscription (Munder Difflin drives your existing claude CLI — it doesn't replace it)
  • For Realtime Michael (voice): your own OpenAI key with Realtime API access — without it the Talk button stays disabled

🛠 Build from source

git clone https://github.com/chaitanyagiri/munder-difflin.git
cd munder-difflin
npm install        # rebuilds node-pty for Electron
npm run dev        # launches the app with hot reload

Node 18+ and a C/C++ toolchain are required (Xcode CLT on macOS, Build Tools on Windows).
To produce installers yourself: npm run dist (current OS), or dist:mac / dist:win / dist:linux.

What's inside

  • The simulation — every agent is a real claude (or agy / codex / local-provider) pseudo-terminal, visualized as an avatar on a watchable office floor (node-pty · xterm.js · Pixi.js).
  • Talk to Michael — a realtime voice channel to the GOD orchestrator that reads the hive and acts behind spoken echo-back confirmation, BYOK and main-only.
  • Selectable engines + per-hire capabilities — each hire (and Michael himself) runs on a pluggable engine, with its own consented skills + MCP catalog.
  • MemPalace — a markdown-first, semantic memory layer the whole office shares; cross-session recall in ~12ms.
  • GOD orchestrator + hive — one agent you talk to routes work to specialists and stays autonomous, escalating only critical items (spend, destructive ops, scope) to you natively, through human-in-the-loop prompts. It can also spawn an ephemeral worker straight from Slack and tear it down safely.
  • Plugs into your setup — your subscription, settings, skills, and MCP servers, plus an integrations registry with a write-only secret broker; /remote-control reaches the whole floor from your phone.
