Diringo is open source (MIT). A browser-to-browser file sharing tool built on WebRTC. Unlike PairDrop, FilePizza, or WebWormhole, Diringo streams files through a Service Worker. No memory buffering. No file size limits. Adaptive 64 KB chunks write directly to disk. Send 1 GB or 100 GB — memory stays flat. End-to-end encrypted (AES-256-GCM). No accounts. No uploads. Just a 6-character code. Built-in chat. Works across networks with TURN relay. Polished dark-mode UI, zero learning curve.
