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
They should all show up. :) lemmy.ml was probably under some load when i crawled it last. I added it manually and they should show up now.
