It includes a minimal TLS 1.3 stack and conforms to RFC 9000 (QUIC v1) and RFC 9114 (HTTP/3), with support for QUIC v2 via RFC 9369. The library has no external dependencies and does not rely on OpenSSL, making it simpler to embed and deploy.\n\nThe package follows a \"bring your own I/O\" design pattern, meaning you control socket operations and concurrency integration rather than the library imposing a specific I/O model. This makes it testable and compatible with different async frameworks. While client-side support is the primary focus, server-side code is maintained. The library supports modern features including post-quantum key exchange (ML-KEM-768), connection migration, OCSP stapling, and encrypted client hello.","worth_installing":"Yes, if you need QUIC/HTTP/3 support in Python and prefer a dependency-free, actively maintained implementation. The library is production-stable and suitable for embedding in client libraries. Not recommended if you need a high-level HTTP client (use niquests or urllib3.future instead) or if you require extensive server-side features\u2014the maintainers prioritize client functionality."},"id":"qh3","links":{"html":"https://skillfed.io/packages/qh3","md":"https://skillfed.io/packages/qh3.md","pypi":"https://pypi.org/project/qh3/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-13","license_spdx":null,"license_treatment":"permissive","name":"qh3","python_support":"supports_current","summary":"A lightway and fast implementation of QUIC and HTTP/3"},"popularity":{"monthly_downloads":2357464,"position":3108,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"1.9.4"}
