Clipp

Clipp is a free, open-source peer-to-peer clipboard synchronization utility developed by martona, currently at version 1.5.0.160, with seven versions released to date. Falling within the clipboard management and network utilities category, the software is designed to share clipboard contents directly between devices on a local area network without routing data through any cloud service. Its primary purpose is to let users copy text and images on one device and paste them on another, supporting Windows, macOS, and iOS as full platforms, while Linux is served by a terminal-only client. Typical use cases include moving snippets of text, links, or screenshots between a workstation and a laptop, transferring clipboard data to a mobile device, and integrating clipboard sharing into command-line workflows. Security is central to the design: connections between devices are mutually authenticated and encrypted using libsodium primitives, so clipboard data travels only across a network the user controls. Devices pair by means of a shared group name and passphrase and confirm a non-secret fingerprint, ensuring that only trusted peers participate in synchronization. A distinguishing feature of Clipp is its treatment of the terminal as a first-class citizen. Alongside the conventional tray application, it provides command-line tools in the form of `clipp copy` and `clipp paste`, functioning as network-enabled equivalents of the familiar `pbcopy` and `pbpaste` utilities. It also supports named registers, invoked through commands such as `clipp copy ` and `clipp ls`, which allow users to store, list, and retrieve multiple clipboard entries rather than being limited to a single shared buffer. This combination of cross-platform GUI support, scriptable terminal access, local-only peer-to-peer transfer, and authenticated encryption makes Clipp suitable for users who want convenient clipboard sharing across their own devices without relying on third-party cloud infrastructure.
