I’ve been working on this for a couple weeks now, if you’ve not seen it then it lets you search/filter communities and instances on all Lemmy instances.
Currently over 1k instances and 26k communities! We’re growing hella fast!
All open-source and up on GitHub
It’s not great on mobile, unfortunately. I made a fix so at least you should be able to see the community name/link. I have to refactor the list a bit as it was rushed in, and there will be improvements soon…
