What is it?

ClipCascade syncs clipboard content between your devices automatically: copy on one machine and the text, image or file becomes available on the others. It supports two modes. In server-based mode, clients connect through a central server, which you can self-host with Docker or a Java 21 JAR, or use the community server at clipcascade.sathvik.dev. In peer-to-peer mode, devices connect directly, with the server used only for signaling and authentication.

The project includes desktop clients for Windows, macOS and Linux (GUI and terminal modes) and an Android app. Clipboard content is protected with end-to-end encryption, and the server supports multiple user accounts, a web dashboard, login brute-force protection and configuration through environment variables. Android background monitoring requires a one-time setup with ADB commands.
