I built this for myself over four months, because I kept paying three subscriptions to do three things on one Mac and none of them could talk to each other. The part I did not expect to matter most: it opens real terminal sessions and can undo anything it did, because every command is snapshotted into a shadow git repo first. That one feature is what made me trust it enough to let it work while I slept. Nobody hands real work to something they cannot reverse. It also runs swarms of agents in parallel, scaffolds and builds iOS apps, captures meetings and tells the speakers apart on device, and reads its own source to propose its next version, which I still review before approving. It is MIT and there is nothing to buy. It runs against your own API key, or entirely against a local model with no key at all. No account, no server, no telemetry. Happy to answer anything, including what it does badly.

I spent about $322,000 of API credits on this, then made it free. Launching here Sunday.

122 days. 547 commits. 160,000 lines of Swift. One native macOS app.

About $322,000 of Claude at API rates went into building it. That is the API-rate valuation of measured usage rather than cash I wired anywhere, and I would rather say it that way than round it up.
