PrivyDrop - A Privacy-Focused, WebRTC-Based File Sharing Tool

PrivyDrop(formerly SecureShare) is an open-source, peer-to-peer (P2P) file and text sharing tool built on WebRTC. It requires no server-side data relay; all data is transmitted directly between browsers, ensuring end-to-end encryption for maximum privacy and security.

We believe everyone should have control over their own data. PrivyDrop was created to fulfill this vision: a simple, fast, and private sharing solution.
