I'm ignorant of the potential advanced offerings of bitwarden, but the idea that storing your passwords - essentially an encrypted csv file - necessitates a) a server/client infra and b) continuous, yearly payments of any amount is beyond ludicrous to me.

as many here, I've also dicked around with vaultwarden, as I already selfhost a buncha stuff, so what's one more. aside from the stack, which is beyond ridiculous, the client app is some electron nightmare that doesn't even have full functionality - you need the web UI for a number of tasks. I mean, how complex can you get!

KeepassXC is free in all senses of the word, the binary is minuscule, its database is easily versioned, backed up and syncthing-ed around and you're done with that racket for good.
