hi, I'm Oscar!
I build the tools I use.
I'm Oscar Ritzén, founder of RIEN Network. Almost everything I build starts the same way: I need it myself, I can't find one that feels right, so I make it.
Things I've made
OScar
My personal dashboard, and now yours: every tool I use, in one place.

All my products are built through my studio, RIEN Network.
how I work
Used every day, then polished.
Every tool in OScar is one I use myself, every day. That's how the small annoyances get found, and fixed, before anyone else has to live with them.
I write down what changes as I go. Every tool has its own guide, and the blog is the diary of what I built and why. And if there's something you wish a tool did, put it on the wish list.
your data stays yours
