KeyCat opensource password manager автор Key.cat

Key.cat can manage all your credentials and lets you share them with others. The idea is to make a password manager that can work offline and sync when there's a connection available to the server. Like an auto-sync keepass.

Everything is encrypted end-to-end using NaCL via tweetnacl.js.
No metadata leaks. No metadata is stored unencrypted.
Single executable for the server.
Can import from keepass (v.3 for now).
Multiple teams and vaults.
Each team and vault can be independently managed and shared with others.
Multiple credentials per site.
API available to third-party software.
