## What it is
aioquic is a Python library implementing the QUIC network protocol (RFC 9000/9369) with a minimal TLS 1.3 implementation and an HTTP/3 stack (RFC 9114). It is designed to be embedded into Python client and server libraries, using a 'bring your own I/O' pattern compatible with asyncio and other concurrency models.

## Use cases
- implement a QUIC client or server in Python
- add HTTP/3 support to a Python web framework
- build a proxy or tool that speaks QUIC like mitmproxy
- test QUIC interoperability in research
- bootstrap WebSockets over HTTP/3 (RFC 9220)
- log QUIC events in QLOG format for analysis

## When to choose
- you need QUIC or HTTP/3 protocol support in a Python project
- you want a reusable QUIC codebase to embed in client/server libraries
- you need fine control over I/O and concurrency models
- you need TLS 1.3, connection migration, datagrams, or version negotiation

## When to avoid
- you just need a high-level HTTP client without QUIC
- you need a full-featured TLS implementation beyond the minimal TLS 1.3 subset
- your project is not in Python
