About Crosspaste Desktop
CrossPaste is an open source application that shares clipboard content between macOS, Windows, and Linux computers. Content is end-to-end encrypted with asymmetric encryption, and the project describes its design as LAN-only and serverless, with local storage and no cloud component.
Beyond basic sharing, the project lists automatic cleanup options for stored history, local text extraction from images, a command-line interface, and an MCP server that exposes clipboard history to AI assistants such as Claude. A Chrome extension can sync clipboard content with the desktop app on the same machine. The repository also lists a plugin system as planned work, not as an available feature.

- Real-time sharing of clipboard content between devices
- Consistent interface on macOS, Windows, and Linux
- Support for text, color, URL, HTML, RTF, image, and file types

Best for: People who use more than one of these desktop systems and want clipboard content shared over their local network, as well as developers who want to build or modify the application.
