ShareDrop is an HTML5 clone of the Apple AirDrop service. It allows you to transfer files directly between devices, without having to upload them to any server first. It uses WebRTC for secure peer-to-peer file transfer and Firebase for presence management and WebRTC signaling.
ShareDrop allows you to send files to other devices in the same local network (i.e. devices with the same public IP address) without any configuration - simply open https://www.sharedrop.io on all devices and they will see each other. It also allows you to send files between networks - just click + button in the top right corner of the page to create a room with a unique URL and share this URL with other people you want to send a file to. Once they open this page in a browser on their devices, you'll see each other's avatars.
The main difference between ShareDrop and AirDrop is that ShareDrop requires Internet connection to discover other devices, while AirDrop doesn't need one - it creates an ad-hoc wireless network between them. On the other hand, ShareDrop allows you to share files between mobile (Android) and desktop devices and between networks as well.
