Your local bitwarden apps „only“ sync with your vaultwarden. So if you‘re not adding and changing multiple entries every day you can just endure an outage of a few hours or even days until you reconnect and sync.
That said, I am very paranoid about hosting my password manager on a publicly available VPS. The VPS provider theoretically has access and if you don’t secure the VPS properly everybody else, too.
So I make VW only accessible via a VPN (wireguard) and only host it locally on a pi. That is also backed up to another pi (Borg with borgmatic).
For me this is a good mix of redundancy, access control and attack vector mitigation.
As an avid podcast listener I use Pocket Casts. But I have been looking for something to replace this, especially to own my listening status and save favourite episodes.
Either I haven't tried it properly enough or there simply isn't anything out there.
My experiences:
Podfetch: Very very basic, can't get Favourites to work, doesn't save specific episodes into a permanent archive, couldn't get playing to work, no mobile apps
Plex: Cancelled Podcast support two years ago
Audiobookshelf: As described by others, performance issues (I have ~117 podcasts and updating takes ages), iOS app is Testflight only and BETA is full. Wanted retest with it being only an intermediary.
