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
I run the crawler portion of the script - I’m looking to run it in a container and have it update every day.
I put a little thing in the top-right menu that shows you when it was last updated (and only data that was updated in the last 24 hours is included).
