What is it?

SyncClipboard syncs clipboard contents between devices. The desktop client runs in the background on Windows, macOS and Linux and pushes clipboard changes to a shared server, so text, images and files copied on one machine can be pasted on another. It also keeps a clipboard history that is synced across devices.

The server can be the built-in server in the desktop client, a standalone ASP.NET Core server (also available as a Docker image), or an existing WebDAV or S3-compatible object storage. Image handling is a focus: copied images can be pasted as files in the file system and vice versa, and images copied from a browser are downloaded at full quality so animated GIFs keep working.

Mobile clients exist for iOS (via Shortcuts) and Android, along with community clients for HarmonyOS. The project publishes a documented HTTP API and sync protocol so third-party clients can be built against it. The history feature is still early-stage, so it should not be the only place important content is stored.

Things to know

  • The clipboard history feature is in an early stage, so data can be lost and important information should not rely on it alone.
  • Linux requires glibc 2.38 or newer.
  • Clients and servers from v3.1.1 onward are incompatible with earlier versions, so all devices must be upgraded together.
