Munder Difflin v0.4.4 — a pixel-art office that runs your agent CLIs

What is it?
Munder Difflin wraps agent command-line tools — Claude Code, Codex, Gemini, Grok, Kimi, Qwen and others — as coworkers in a desktop app. Each agent is an avatar at a desk on a pixel-art office floor, and a supervising agent called Michael routes tasks and escalates decisions back to you. Version 0.4.4 landed on August 18.
How does it work?
Two planes run side by side. The terminal plane spawns each agent as a real node-pty process running an actual CLI session, so nothing is simulated. The hive plane handles on-disk memory, atomic mailboxes, message routing and a shared blackboard, which is what lets agents keep context between sessions and hand work to each other.
Why does it matter?
Most multi-agent setups hide coordination inside a log file. Seeing envelopes fly between desks makes it obvious which agent is stuck and which is talking to whom, which is the part that usually goes wrong. The v0.4.4 release also unblocks Windows users, where a command-line argument truncation bug had stopped agents messaging each other entirely.
Who is it for?
