AirDrop-style Windows sharing

An open-source AirDrop alternative for Windows.

Direct answer

Lightning P2P is an open-source AirDrop-style file transfer app for Windows, focused on direct-first transfers, QR/link handoff, no account, and no cloud upload.

If you need AirDrop-like sharing outside the Apple ecosystem, Lightning P2P focuses on direct device-to-device transfers, nearby discovery, QR tickets, and no artificial file-size caps.

The stable public release supports Windows and Android 10+ sideload users. Apple AirDrop interop is not claimed; Lightning P2P transfers require Lightning P2P on both ends.

Download the recommended Velopack one-click installer, the classic NSIS setup installer, or the MSI installer. Android users can sideload LightningP2P-android-latest.apk and verify it with SHA256SUMS-android.txt. Signing status, SmartScreen notes, Android sideload notes, and SHA256 checksums are available on GitHub Releases. App version: v0.5.1.

Important caveats

  • Sender must stay online until the receiver finishes.
  • Tickets are capability tokens and should be treated as secrets.
  • Relay fallback helps connectivity, but it is not cloud storage.
  • Browser website is receive handoff and marketing, not the transfer engine.
  • Public speed leadership claims require repeatable benchmark results.
