PodOsef is an MP3-first podcast publishing system: drop MP3s into a folder, it generates HTML + RSS. No DB, the MP3 metadata is the source of truth. Also supports an archive mode that watches a main feed and mirrors episodes. Repo + write-up:

I deleted previous post as I managed to screw it up pretty good. There was a comment that the entire “mp3-first” idea is outdated… That might be true. However I developed it based on my requirements. I think if there is enough interest, software/design can be updated.
By the time I finished with the software, I had at least few different ideas for the future, but I stopped where I stopped, just because I got everything I needed. I keep my mind open, if there is enough interest, perhaps software can be enhanced and developed further.
