We've been using PreMiD for years and eventually decided to build our own alternative.
Nowly is an open-source browser extension that automatically displays what you're doing on the web as a Discord Rich Presence.
It supports a growing list of websites and is designed to be easy to extend with new presences.
The project is built with an open-source-first approach, and we'd really appreciate feedback from the HN community, especially around the extension architecture and developer experience.
