I’m migrating from Pocketcasts and Audible to a self-hosted Audiobookshelf instance. It’s got all the audiobook features I would want, but the podcast features are not quite there yet. The two big ones that I miss from Pocketcasts are an automated “up next” playlist and auto-downloading new episodes to the phone. That being said, there is active development and new features and bugfixes come out regularly. I wouldn’t be surprised if it had feature-parity with Pocketcasts within the year. I know self-hosting isn’t for everyone, but if you’re interested in playing around with something like that, audiobookshelf is a good place to start.
