Private P2P clipboard sync for local networks and devices
Copy on one device and paste on another using encrypted peer-to-peer transfers over your local network, handling both text and images without accounts or servers. Clipp, developed by martona, runs on Windows and other major platforms as a lightweight clipboard synchronizer. It uses libsodium for end-to-end encryption, a LAN-first discovery method, and an activity stream to view recent items. This makes it suitable for privacy-conscious multi-device users and developers who want local-only sharing.
What the app actually does and how it connects devices
Clipp uses a serverless, peer-to-peer model to move clipboard data directly between paired machines on the same network or connected via a trusted VPN or mesh network. It supports both text and image formats and exposes an activity stream to inspect and manage recently received items. The open-source codebase and the developer's networking background explain the focus on direct LAN discovery rather than routing through third-party servers.
Does it affect system performance during continuous synchronization?
Clipp is designed to be lightweight in operation, with a LAN-first discovery that reduces unnecessary network chatter when devices are local. The app transfers clipboard items directly, so it avoids periodic cloud polling. Because transfers stay within the local network or VPN, ongoing background activity is limited to discovery and occasional encrypted transfers rather than constant upload or download use.
Is it safe to use on production or private networks?
Security is enforced with end-to-end encryption using libsodium primitives, and the project follows a zero-telemetry, zero-analytics policy. In addition, no registration or external servers are required, which keeps data off third-party infrastructure. For cross-network use, the recommended path is a trusted VPN or mesh network so transfers still avoid public intermediaries.
Do I need technical knowledge to set up and operate it?
Clipp aims for minimal friction: no accounts or servers to configure, so basic pairing and LAN discovery are accessible to most desktop users. In addition, developers or advanced users can inspect the MIT-licensed repository on GitHub. Nevertheless, using the app across separate networks requires familiarity with VPNs or mesh networking to maintain the same local-traffic behavior.
Who should use Clipp, and the main trade-off to consider
Clipp suits users who prioritize keeping clipboard data within their control and who frequently move text or images between nearby devices. The main trade-off is its LAN-first design: to sync across different networks you need a trusted VPN or mesh link, which adds a setup step that some users may find inconvenient. Use local discovery on trusted Wi-Fi and enable a VPN for remote device links.
