Snapdrop is inspired by Apple's Airdrop, but is a Progressive Web App built with Polymer and Web RTC.

• Polymer
  • Polymer Starter Kit
  • Polymer Elements
• WebRTC
  • PeerJS
• WebSockets fallback (iDevices don't support WebRTC)
  • BinaryJs

It uses a P2P connection if WebRTC is supported by the browser. (WebRTC needs a Signaling Server, but it is only used to establish a connection and is not involved in the file transfer).

If WebRTC isn’t supported (Safari, IE) it uses a Web Sockets fallback for the file transfer. The server connects the clients with a stream.

None of your files are ever saved on any server. Snapdrop doesn't even use cookies or a database. If you are curious have a look at the Server But it does use Google Analytics.

No. ShareDrop is built with ember. Snapdrop is built with Polymer. I wanted to play around with Progressive Web Apps and then I got the idea to clone Apple’s Airdrop. By doing research on this idea I found and analysed ShareDrop. I liked it and thought about how to improve it. ShareDrop uses WebRTC only and isn't compatible with Safari Browsers. Snapdrop uses a Websocket fallback and some hacks to make Snapdrop work due to the download restrictions on iDevices.
