Cons
Con Backups are up to the user
There is no service with this application, it is up to the end user to backup all data.
Con Has to be running on a server to work
Unlike other password managers such as KeePass, Clipperz can not just be simply run by executing once downloaded. It has to be setup to run on a server and then can be accessed from the necessary devices.
Con Dark theme on macOS needs some work
The tabs for multiple databases and about menus are unreadable in dark mode on macOS.
Con Qt dependency hell
Con Browser plugin doesn't always connect to KeepassXC on the first attempt
Restarting the Browser or restarting KeePassXC fixes the integration.
Enabling "Automatically reconnect to KeePassXC" option in KeepassXC Browser Extension fixes this problem permanently.
Con Non native UI
