I’ve seen this idea floated before a few times, and it’s a thought I’ve had before myself–some sort of self-hosted version of gify. AFAIK nothing exists as of writing, but I’ve seen this idea crop up enough times that maybe there’s a demand for this sort of thing.

Personally, I just have a well-organized meme folder that I sync between my client devices with syncthing, but something a little more integrated and easier to search might be fun.
