I'm working on an alternative to KeePass/KeepassXC called Lockstep - it is local-first password manager that supports sync natively.
It uses SQLCypher as local data store and keeps KeePass-compatible data model - supports import of .kdbx database.
SQLCypher and different schema used in Lockstep alone did not solve any problems that I have with Keepass. Those problems are sync and sharing.
Solving sync and sharing cannot be done on whole database file level, as it implemented now in KeePass. Changes need to be tracked at the password record level, all changes need to persisted as operations log and that log needs to be distributed across devices.
The above means writing a whole protocol, and that's a lot more work than changing local storage.
