I used Bitwarden for several years now. Runs on everything I own, allows you to store passwords on your own infrastructure or just about anything else, open source, allows sharing of passwords between multiple users, a very serviceable UI and a responsive developer. It's about as good as a small software project gets.

The one criticism I have can be leveled at most of these things, and that is a privileged user (eg, root) can dump most of your passwords once you have unlocked them by scanning memory. Lastpass in particular does a really good job of circumventing this (but of course has an even bigger security flaw - its closed source). Unfortunately I suspect this is really hard to fix in something written in Javascript. But do be aware of this flaw and never use the Bitwarden on a multi-user machine.
