Hey Product Hunt 👋

It’s 2026 and building a digital clone of yourself to do all your work is possible with a claude subscription.

So I built Munder Difflin: A local multi-agent harness that uses your existing coding agents like claude code and codex to run in an office of persistent agents that does your work. Decisions run through you or a clone of you that orchestrates.

If whatever’s written above does not make sense:

It’s a free and open source PC app that runs an office of agents that can do literally anything you do on your own computer with your context, you get to see them work in a “the office” themed simulation.

Be the boss of this office yourself or let a clone be the boss when you are not available.

I have made it open source which means it is available for the whole world for free to use, it runs locally which means no personal data goes anywhere, it’s ad-free and lastly it means I did it for the love of the game.

We started from v0.0.1 about 40 releases and 2 months later we are at v0.4.1

Over 2000 people use it already, along with 677 github stars and we are finally live on Product Hunt help please upvote and share about Munder Difflin to help us get to #1 on PH today.

[No setup needed if you use claude code, codex or any cli agent]

Two things people always ask:

- "Isn't that a fortune in tokens?" I run it on a $100/mo Claude plan —
one Opus orchestrator, nine Sonnet workers. Shipped continuously for weeks without hitting a limit. The cheap models do the work; the expensive one decides who does what. You can use a mix of agents from different providers to run it way cheaply.
[Simulation is deterministic, they do not consume token]

- "What's the catch?" There isn't one. MIT licensed, free forever, runs
entirely on your machine. Your code never touches my servers because I
don't have any.

I'd genuinely love your feedback, especially on what breaks. I'm here all
day.
