qh3 is a fast QUIC and HTTP/3 implementation for Python, backed by a native Rust transport core. It is a maintained fork of aioquic and is not a drop-in replacement.
It provides:
a convenient asyncio client and server API;
sans-I/O QUIC and HTTP/3 APIs for custom integrations;
QUIC v1 and v2, TLS 1.3, IPv4 and IPv6, migration, QLOG, datagrams, server push, WebTransport streams, ECH, and post-quantum key exchange;
support for CPython and PyPy 3.7 or newer.
Installation
python -m pip install qh3Documentation
Read the qh3 documentation for the getting-started guide, asyncio and sans-I/O integration guides, and the supported public API reference.
Only interfaces listed in the public API reference are covered by API compatibility guarantees. In particular, qh3._hazmat and underscore-prefixed modules are implementation details.
Complete examples are available in the examples directory. Applications looking for a complete HTTP client should generally use Niquests or urllib3.future.
