Self-hosted podcast aggregator/streamer, NOT downloader
So I'm looking for a solution that is a self-hosted (docker preferably) podcast streamer/aggregator. I DO NOT NEED A DOWNLOADER. Ideally, I'd be able to add RSS feeds and stream them through a web interface that will keep track of progress, etc. I'm not talking about something that serves up downloaded podcasts either, I can do that in Plex/Jellyfin.
Maybe Audiobookshelf? You can set up podcasts and stream them from the web interface. It'll keep track of your progress, so you can switch from web to phone and pick up in the same spot.
Edit: though it does download the podcast to the server so that you can stream it, but it grabs them automatically.
