A QUIC implementation in pure Go

quic-go is an implementation of the QUIC protocol (RFC 9000, RFC 9001, RFC 9002) in Go. It has support for HTTP/3 (RFC 9114), including QPACK (RFC 9204) and HTTP Datagrams (RFC 9297).

In addition to these base RFCs, it also implements the following RFCs:

• Unreliable Datagram Extension (RFC 9221)
• Datagram Packetization Layer Path MTU Discovery (DPLPMTUD, RFC 8899)
• QUIC Version 2 (RFC 9369)
• QUIC Event Logging using qlog (draft-ietf-quic-qlog-main-schema and draft-ietf-quic-qlog-quic-events)

Support for WebTransport over HTTP/3 (draft-ietf-webtrans-http3) is implemented in webtransport-go.

Detailed documentation can be found on quic-go.net.
