Munder Difflin v0.4.0

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

What's 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-0.4.0-mac-universal.dmg

🪟 Windows

Build File
Installer (x64) — recommended Munder-Difflin-0.4.0-win-x64-setup.exe
Portable (x64, no install) Munder-Difflin-0.4.0-win-x64-portable.exe

🐧 Linux

Build File
AppImage (x86_64) Munder-Difflin-0.4.0-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.
