About Teccsa File Transfer
⚡ Direct Peer-to-Peer (WebRTC): Teccsa connects two browsers directly using encrypted WebRTC DataChannels. Files stream directly between your devices at physical local network speeds.
🔒 Zero Server Storage: No server ever sees, processes, or stores your files. Initial signaling only passes the tiny 1KB network handshake to negotiate the direct connection.
📦 Large File Friendly: Teccsa slices files into 64KB binary chunks with automated backpressure flow control, preventing browser tab memory crashes on files of any size (even 10GB+).
📱 Device Agnostic: Works across any computer, phone, or device on your network.
