crosspaste-desktop

CrossPaste syncs your clipboard across Mac, Windows, and Linux in real time. Copy on one machine, paste on another. Supports text, URLs, HTML, RTF, images, colors, and files. Everything stays on your local network with end-to-end encryption. No cloud server involved.

Runs as a desktop app built with Kotlin and Compose Multiplatform. No server to set up. Devices discover each other automatically on the same network. Uses asymmetric encryption for security and SQLite for local storage. Smart cleanup keeps clipboard history from eating your disk.

Free for everyone. No paid tier, no accounts, no telemetry. Solo developers working across multiple machines will use this daily. Teams in the same office get effortless sharing without any IT setup.

The catch: LAN-only means no syncing between home and office unless you set up a VPN. If you need cloud sync across locations, this is not the tool. Look at paid options or set up Syncthing as a workaround.
