KubaOS.
The local-first founder OS.
A private desktop cockpit for a solo founder — interviews, pains, features, build logs, metrics, launch tasks, content calendar, and focus mode, all in one place. Your data lives on your machine.
One cockpit for the whole founder loop — local, private, yours.
KubaOS replaces five tabs, three spreadsheets, and a notion doc with one desktop app. Built for a solo founder who wants the operating picture in one place without shipping it to a third party.
Interviews → Pains → Features
Capture customer conversations, extract pain points, and link them to the features that solve them. The whole insight trail lives in one graph.
Build log & launch tasks
A structured timeline of what shipped and why, next to the tasks that move your launch forward. No more guessing what week 14 looked like.
Metrics & content calendar
Track the numbers that matter alongside the posts, videos, and shipping moments you're planning. Story and system in one view.
Focus mode & forum
A zero-distraction today view, plus a private async thread stream for side conversations with the handful of people you actually talk to.
Closed source. Hardened on purpose.
KubaOS is a personal tool shipped as a signed binary. It's designed so that if it's the only app on your machine, your data still never leaves unless you choose to sync it.
