> gpodder.net

Not sure quite what's going on with that project but when I looked - gpodder.net was a subscription service and the foss project was somewhat hidden and renamed as mygpo. Felt a bit suss and abandoned although I guess an rss server could just be "done".

There is also opodsync that seems to be a bit more alive and popular and says it's gpodder compatible. Not tried it though.

My enthusiasm to self-host my podcast/rss feed was killed dead when I gave nextcloud another go since it can apparently do this. Every few years I set it up having forgotten that the last time I did, I swore to never touch it again. I can't believe it's still such a bad experience.
