Summary
PairDrop is an open-source web application that facilitates easy and secure file sharing between devices on the same local network. It functions much like AirDrop but works across various platforms via a web browser, requiring no installation or signup.
Problem Solved
Traditional methods of transferring files between devices often involve cumbersome steps like using cloud storage (with privacy concerns and size limits), emailing files (size limits, slow), or using cables. PairDrop solves this by providing a fast, private, and direct way to share files locally without any intermediaries or setup.
