Munder Difflin

Munder Difflin is an open-source harness that wraps a CLI coding agent you already have — Claude Code, Codex, Grok, Kimi Code, Antigravity, Qwen, OpenCode, Crush, Pi or Copilot — and gives it an identity, a workspace, a memory and an autonomy setting. The result is what the project calls a clone: an agent configured with your tooling and your context that keeps working when you close the laptop.

How it is put together

Each clone is a personal node that its owner controls, not a tenant in someone else's orchestrator. You give it a name and character, point it at a folder with an isolation and resume policy, choose the provider and model that drive it, and write a briefing that states its goal. Clones talk to each other over an end-to-end encrypted clone-to-clone network, which is how a handoff between, say, a developer's clone and a product manager's clone happens without a shared inbox.

The autonomy dial is the interesting part: a clone can be held to propose-and-wait, or allowed to act inside a defined boundary, so the same harness covers both supervised and unattended work.

Licence and code

MIT licensed, with the node, the protocol and the cryptography all public at github.com/chaitanyagiri/munder-difflin. Running it solo and locally costs nothing and needs no account — the paid tiers exist for people who want the clones hosted rather than for people who want the software.

Pricing

Solo Local is free. Solo + Cloud puts your clone on a dedicated VM so it runs 24/7 (indie pricing on request). Teams Lite adds clone-to-clone messaging and a shared organisational knowledge base; Teams PRO gives every clone its own sandbox VM, with plans from 10 to 100+ seats. A one-off $20 Founding Supporter donation buys a name on the Founders' Wall and nothing functional.

Built by Chaitanya Giri. The pixel-art Dunder Mifflin styling is a joke that runs all the way through the UI, but the underlying model — bring your own agent, own your node, encrypt the network — is a serious answer to the question of what a multi-agent team should look like when nobody wants to hand their code to a hosted platform.
