ClipCascade
Utility that automatically syncs the clipboard across devices
...The software supports both centralized server synchronization and direct peer-to-peer connections. End-to-end encryption protects clipboard contents during transmission. Users can deploy their own server using Docker or Java, or connect through the available community server. A web dashboard provides access to clipboard activity and synchronization settings. Multi-user support, authentication, and per-device transfer controls make ClipCascade suitable for personal and shared environments.
