What are the most well-designed open-source products?

Plugging in what we are building with Rowy (https://www.rowy.io) to the list 😊

Dub.sh is really, really clean 🥰 Also they allow for swanky links like this: https://documen.so/ph

Hanko is pretty well designed! 😁

From the list i also prefer Hanko, the design is really nice and clean. Also Krita is a nice open source alternative to Photoshop. I don't want to promote my own product, but for a machine vision application, where most of the time they are too complex to keep the design simple, i think AyBorg is well designed.

Would you consider Wikipedia as the OG open-source product? If so I think they've done a terrific job
