## What it is
quic-go is a production-ready, pure Go implementation of the QUIC transport protocol (RFC 9000/9001/9002) with support for HTTP/3, datagrams, connection migration, multipath, and qlog event logging. It enables Go applications to run QUIC servers and clients, serve HTTP/3 alongside HTTP/1.1 and HTTP/2, and build related protocols like WebTransport and MASQUE proxying.

## Use cases
- serve HTTP/3 from a Go web server
- build a QUIC client or server in Go
- implement low-latency streaming over QUIC streams and datagrams
- proxy UDP or IP traffic over HTTP (CONNECT-UDP / CONNECT-IP)
- add connection migration and multipath to a networked application
- log QUIC connection events with qlog for debugging
- build real-time web communication with WebTransport

## When to choose
- you need QUIC or HTTP/3 support in a Go application
- you want a mature, widely used, RFC-compliant QUIC stack
- you need advanced QUIC features like 0-RTT, datagrams, connection migration, or multipath
- you are building proxies or tunnels using MASQUE-style HTTP proxying

## When to avoid
- your project is not in Go
- you only need plain TCP-based HTTP/1.1 or HTTP/2 without QUIC
- you need a QUIC implementation for a non-Go runtime with different language requirements
- you need WebTransport itself - use the companion webtransport-go project built on top of quic-go

## Facets
- artifact type: library
