I just created awesome-lemmy based on the well-known awesome lists.
There is already a awesome-lemmy-instances which is specialized in Lemmy instances but no general list that’s why I created one.
It’s forked from awesome-scala which has a very neat python script to easily add new projects so it should be quite easy to contribute, feel free to add tools, apps and websites linked to lemmy!
I also suggest making a pull request to the lemmy readme , removing the listed software and having a link to awesome-lemmy, also having awesome-lemmy under the lemmyNet github organisation could improve discoverability.
