Illustrated portrait of Piotr Kulpinski

I build small software products and run them myself.

I've been writing software for 15+ years, first in agencies and product teams, and now on my own from Kraków. Most of what I make is directories, SaaS tools, and the boilerplate that powers both.

I like simple interfaces and short feedback loops. AI agents write a lot of my code these days, so I ship more than one person probably should. I build in public, and most of what I learn ends up in my writing.

Now

Most of my time goes into Highseat, cookieless web analytics that ties revenue to the source that brought it.

OpenAlternative and Dirstarter keep running alongside it. One is the largest directory of open source software, the other is the Next.js boilerplate behind a growing number of indie directories.
