I believe KeeWeb is one of the more developed cross platform applications for KeePass password databases. Keeweb does not have its own online database to sync your passwords. KeeWeb offers a full complement of features that include auto-advanced search options, clipboard clearing, auto-locking, attachment support, field protection, shortcuts, a password generator, and the ability to set password expiration. KeeWeb includes options for password organization like groups for specific types of passwords for easy reference and retrieval. This fact allows the opening of KDBX files as well as locally storing them or you can sync it with various Cloud services like DropBox, Google Drive, OneDrive, etc.

As mentioned above, KeeWeb is compatible with KeePass, utilizing the KDBX format for password storage. Everything that you need is within a click. You can easily store all your passwords from a secure database that features a sleek, intuitive interface.
