quic-go is an implementation of the QUIC protocol (RFC 9000, RFC 9001, RFC 9002) in Go.
Other QUIC specifications:
- 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)
- QUIC Stream Resets with Partial Delivery (draft-ietf-quic-reliable-stream-reset-07 and draft-ietf-quic-reliable-stream-reset-09)
quic-go also supports HTTP/3 (RFC 9114).
Other HTTP/3 specifications:
- QPACK: Field Compression for HTTP/3 (RFC 9204)
- Extensible Prioritization Scheme for HTTP (RFC 9218)
- HTTP Datagrams and the Capsule Protocol (RFC 9297)
Related projects:
- webtransport-go implements WebTransport over HTTP/3 (draft-ietf-webtrans-http3).
- masque-go implements CONNECT-UDP (RFC 9298).
- connect-ip-go implements CONNECT-IP (RFC 9484).

Starting with v0.60, quic-go supports use in FIPS 140-3 environments when built with Go 1.26 or newer, using Go standard library cryptography for the QUIC code paths relevant in FIPS mode; see FIPS140.md for details.
