Someone just posted this link for both Lemmy and Kbin: Lemmyverse.net

It defaults to Lemmy communities, but if you go to the right top corner menu you can choose Kbin magazines.

That's an interesting scraper tool. Be nice if you could change the size of each display to show more per page. Any idea if it is open source? One could modify it to scrape kbin instead of Lemmy probably.

I haven't and don't find anything like that (yet), but perhaps someone will eventually, maybe after seeing your post. Plenty of coders around. The "good" thing is that kbin.social seems to be the biggest one, so listing its magazines gives you most of what's out there.

I'm going to integrate kbin magazines into browse.feddit.de sooner or later...

For Lemmy, there is another tool to search communities and also instances: https://lemmyverse.net/communities

I don't know any for kbin yet, so far I use the magazine search on kbin.social.
