Because it's relevant and I'd love to see Lemmy get more popular, I'll post olowe.co/lemmy which provides a Client to the Lemmy HTTP API.
A little unusual is that I created a filesystem interface using io/fs. See FS. I used that to create an alternative Lemmy frontend for a kinda obscure text editor I use. See https://lemmy.sdf.org/post/1035382 For example the comments of that post are available at the path:

Only a small amount of the Lemmy API functionality is implemented but I'm filling it out slowly. Any patches appreciated ;)
