## What it is
libquic is a standalone C++ library packaging Chromium's QUIC implementation with minimal dependencies (only embedded BoringSSL), built via CMake. It serves as a reference for implementing the QUIC multiplexed UDP transport protocol and for building language bindings like goquic.

## Use cases
- add QUIC protocol support to a C++ application
- build a low-latency UDP-based transport instead of TCP+TLS
- create language bindings for QUIC (e.g., Go, Python)
- integrate QUIC into an HTTP server like nginx or Apache
- experiment with QUIC connection migration and multiplexing
- reduce connection establishment latency for mobile clients

## When to choose
- you need a self-contained QUIC library with no external dependency installs
- you want to build language bindings from a minimal C++ QUIC codebase
- you need Chromium's QUIC implementation extracted for integration into C/C++ code

## When to avoid
- you need modern QUIC / HTTP/3 support - this tracks the older Google QUIC era of Chromium
- you want an actively maintained library with recent upstream syncs
- you prefer a higher-level QUIC implementation like ngtcp2, quiche, or msquic
- you need production support and documentation beyond Chromium's toy client/server examples
