KeepassDX can quick unlock with the device pin or with biometrics but the major hassle vs bitwarden is the management of syncing the database, which can be opened as file from the mobile and the desktop app also at the same time, instead bitwarden access your pwd database only remotely and only querying it, but the file is opened only on the server.

But browsers plugin work in the same way, they connect to the local app like it was a server, so it might be possible in the future that there will be an app which can access the db remotely, with this being opened only from the app on the desktop.
