I use Keepass. Reasonable security but ugly gui in linux due to mono. Has plugins. Completely offline.
I can't yet wean myself off of LastPass though, just because it's synced everywhere and is more reliable when doing form fills on websites. For example, KeePass and its variants don't have a concept of equivalent domains. For "equivalent domains" I should be prompted with the same lists of auto-fillable credentials, such as:
* youtube.com/google.com/gmail.com
* bing.com/hotmail.com/live.com/microsoft.com/msn.com/passport.net/windows.com
* apple.com/icloud.com
LastPass gets this right, but I sadly haven't seen any other password manager that does. I think there's an open issue with KeePassXC to address this but it's not merged or production ready.
The problem is that they can't deviate from the official KeePass database format, so adding something like aliases requires hacks like the above.
Other than that it has better gui if that is your thing (Keepass is ugly). It is mostly a fork of keepassx which is still usable but KeepassXC merged all pull requests and fixed a load of bugs in keepassx after the maintainer stopped maintaining. Try it. It works. It also has mutilple releases (snap, appimage etc.).
How has your experience with it so far?
It is absolutely rock solid.
I'm not sure that KeepassXC can be considered unmaintained - their last release was in June, this year - https://keepassxc.org/blog/ . Also note the monthly tone of the updates - even the koolist of kool dev kids kant complain that is slow 8)
+ kpcli for TTY use, keepassdroid for android, sync to owncloud, voila.
If you are extra concerned with security after storing your file remotely, you can have it use an addtional external keyfile in addition to the which you manually copy to 'authorize' devices
