Looks a lot like https://snapdrop.net, but idk wich came first. It's both open-source but I can't find a link between those two

I needed an alternative to Airdrop and stumbled upon this. This is super convenient and fast for quick file transfers. How to use it? Sharing files between devices in a local network* To send a file to another device in the same local network, open this page (i.e. www.sharedrop.io) on both devices. Drag and drop a file directly on another person's avatar or click the avatar and select the file you want to send. The file transfer will start once the recipient accepts the file. Sharing files between devices in different networks To send a file to another device in a different network, click + button in the upper right corner of the page and follow further instructions. Security ShareDrop uses a secure and encrypted peer-to-peer connection to transfer information about the file (its name and size) and file data itself. This means that this data is never transfered through any intermediate server but directly between the sender and recipient devices. To achieve this, ShareDrop uses a technology called WebRTC (Web Real-Time Communication), which is provided natively by browsers. Feedback If you hit a problem while using ShareDrop or have a suggestion on how to improve it or just want to say hi? Send an email to support@sharedrop.io or report an issue on GitHub: https://github.com/szimek/shared....

This is cool! Can I ask why you were looking for an alternative to airdrop?

Does this work for mobile as well?
