You can get rid of the element of hope by using KeepassXC and syncthing. Bonus is you can use this FOSS stack completely offline.

If you're going to the trouble of self-hosting, I'd suggest just running vaultwarden.

https://github.com/dani-garcia/vaultwarden

It's entirely compatible with the clients. It also removes a lot of "rug-pull" potential, and gives you the ability to access all the nice features (ex - multi-org, multi-user, shared vaults, totp, etc...)

Honestly - part of the reason I like Bitwarden is that if they ever go full "enshittification", it's going to be relatively easy and straight-forward to just move entirely off their projects and onto open-source forks.

It is absurdly easy to fire off the docker container you mean.

Because you need to back up, verify backups, monitor availability, manage updates, manage MFA, and a zillion things.

Don't get me wrong, I work in hardcore, high tech IT for 30 years and I selfhost two dozen or so of services. It is far, very far from "absurdly easy" when you start .

Sure you can run a container on your pc, and hope for the best
