XQuic (@xof/quic) is a low-level QUIC v1/v2 & HTTP/3 stack for Node.js 20+. Built as a foundational block for real-time and multi-region systems, it features connection management, TLS 1.3 (Cert/PSK), multiplexed streams, flow control, loss recovery, QPACK, and HTTP Datagrams. It operates as a protocol layer, not a drop-in client replacement.

Production-grade HTTP/3 server for Python, Node.js, and Rust. Native QUIC transport — no proxy.
