I made this website to crawl and display Lemmy instances since the existing ones were lacking certain filtering and search options.
I have licensed it as MIT and the code is on https://github.com/tgxn/lemmy-explorer
Let me know if there’s any issues, and create a GitHub issue if you want some features :D
Thanks for the feedback! The reasoning for the banners thing was that the best communities should have one set, and there are a lot of communities, and the display looks better with them 😁
There was another comment on this, so I’m just deploying a change that will have it default to not hide them.
I could also definitely improve the layout for communities without a banner and instead show some additional details about them (longer description, languages, etc)
Regarding uptime, I don’t really want to have to monitor every instance, but as I’m looking to build a “Join an instance” page I will want to have this data, I may look to use a similar method to this one which uses https://api.fediverse.observer/
