About
Hi, I'm Kellen.
I'm building opub so open source maintainers don't pay for AI coding tools out of pocket.
I've spent years at Fly.io, Elastic, and QuestDB. Open source runs underneath all of it. The people maintaining that code are largely volunteers, and the cost of keeping up with agentic tools is landing on them.
opub is my attempt to help with that — find donors, keep the models current, and stay out of the way.

Why opub
Compute is becoming a cost of maintaining open source. The projects everyone relies on should be able to use the same tools as the companies building on top of them — without paying out of pocket.
opub's promises are simple: top models, privacy, security, and a permanent public record of donations and spend. The platform makes agentic development free and fun, and gives donors confidence without turning maintainer work into a public record.
