In my opinion, Enpass has the best balance of privacy, open-source, offline-first, etc. It's essentially a proprietary UI over a sqlite/SQLCipher database (fully open source CLI available: https://github.com/hazcod/enpass-cli https://github.com/hazcod/enpass-cli). It can - but needn't - be sync'd any number of ways (iCloud, Dropbox, Google Drive, OneDrive, WebDAV), if that's what you like. Because it has WebDAV sync support, you can use it with ownCloud or NextCloud without much fuss, and not have to trust a third party at all.
