What is it?

PasteFerry syncs what you copy between your own computers, so text, rich text, images, files and whole folders copied on one machine can be pasted on another. Devices are paired once with a code, and after that no shared Apple ID or account is needed. Copied items are kept in a history of the last few days, which you can search and open with a global shortcut to paste into the current app.

Connections are direct by default: computers find each other over the local network with mDNS, or across networks through NAT hole punching using WebRTC. A signaling server, either the official service or a self-hosted one, only helps the two peers exchange connection details, and an encrypted relay is used only when a direct connection fails. Pairing checks fingerprints on both screens, and messages are signed.

The project also includes a Send Files feature for transferring large files with resume and SHA-256 verification, and contact-based sending that requires the recipient to accept each batch. A phone web page works in any browser on the same network, and the project is written in Dart (Flutter) with a Go server, licensed under AGPL-3.0.

Key features

  • 01Syncs text, rich text, images, files and folders between paired devices.
  • 02Direct connections via mDNS on the LAN and WebRTC NAT traversal across networks.
  • 03Relay fallback only, with end-to-end encrypted traffic the server cannot read.
  • 04Searchable clipboard history with a global shortcut for quick paste.
  • 05Send Files with resume, progress display and SHA-256 verification.
  • 06Phone web page for transferring content from any browser on the same network.

Use cases

  • Copying a link or snippet on a Mac and pasting it on a Windows PC without an Apple ID.
  • Sending large files between computers on different networks without uploading them to a cloud drive.
  • Keeping a searchable history of recently copied items across several machines.
  • Transferring photos or files between a computer and a phone on the same Wi-Fi network.

Quick start

  1. 1

    Download and install the app on each computer from the download page

  2. 2

    Pair the computers: on one, choose Devices → Add device → Show a code; on the other, choose Enter a code

Things to know

  • The Mac app is not notarized by Apple and the Windows app is not code-signed yet.
  • The Android app is beta, and there is no iPhone or iPad app.
  • The official relay allows 100 MB a day when a direct connection fails.
  • Licensed under AGPL-3.0, so distributing it or offering a modified version over a network requires publishing your source.
