CrossPaste/crosspaste-desktop

Cross-device clipboard sync for macOS, Windows & Linux — end-to-end encrypted, LAN-only, no cloud. OCR, CLI and MCP server built in.

What it solves

CrossPaste solves the difficulty of sharing clipboard content across different devices and operating systems. It allows users to copy text, images, or files on one machine and paste them on another without relying on a central cloud server.

How it works

The application uses a serverless, LAN-only architecture for local storage and synchronization. To ensure privacy and security, it employs asymmetric end-to-end encryption. It also includes a local OCR engine to extract text from images without sending data to the cloud, and an MCP server to make clipboard history available to AI assistants.

Who it’s for

It is designed for users who work across multiple computers (Windows, macOS, and Linux) and need a secure, private way to sync their pasteboards, as well as developers who want to interact with their clipboard via a command-line interface.
