Zephyr
// PEER TO PEER on macOS, Windows, Linux

Files, anywhere.
Instantly.

Share files with devices nearby or friends across the world, with a single shortcut.

Download for macOS

Select. Shortcut. Sent. No app to open, nothing to drag.

// PERSONAL DEVICES

All your devices, as one.

Pair your devices once and they trust each other from then on, across macOS, Windows and Linux.

Copy here, paste there.

Copy text on your Mac and paste it on your Windows PC. Your clipboard follows you across every paired device.

Files fit in your clipboard too.

Copy any file up to 25 MB and paste it on another device, just like text. No share window needed.

No prompts between your own devices.

Paired devices trust each other, so files arrive right away without you having to accept them.
// SECURE & PRIVATE

Your files, for your eyes only.

Files go straight from your device to theirs. If a firewall gets in the way, a private relay passes them along, still end-to-end encrypted.

  • No account
  • E2E encrypted
  • Peer to peer
  • Open source
  • Nothing stored online

Pricing Free. No catch.

Everything Zephyr does today is free and open source, forever: file sharing, personal devices and clipboard sync. No trial, no "free for now."

We're building optional paid features on top, starting with file sync. They'll keep the free app getting better, and nothing you use today will ever move behind a paywall.
