UniClipboard is a free, open-source clipboard manager designed to synchronize copied content securely across multiple devices. It uses peer-to-peer connections and end-to-end encryption to transfer text, images, and files without requiring cloud accounts. The software supports communication over local networks and the internet, with encrypted relay connections when direct transfers are unavailable. Users can search an encrypted clipboard history and retrieve previous items through a keyboard-accessible Quick Panel. Device pairing uses invitation codes and shared passphrases. Additional controls allow users to manage synchronization preferences and connected devices individually. Available for Windows, macOS, Linux, Android, and iOS, UniClipboard provides a privacy-focused solution for cross-device clipboard management.
