It uses SIMD instructions (SSE4.2 on x86, NEON on ARM) and lazy object creation to minimize overhead. The package provides multiple parsing modes: a basic dict-returning parser, a zero-copy fast parser with lazy property access, a callback-based protocol handler for asyncio integration, and raw offset-based parsing for maximum speed.\n\nIt handles common HTTP parsing tasks\u2014extracting method, path, headers, and version\u2014while enforcing limits matching Gunicorn's defaults. It can generate WSGI environ dicts or ASGI scope objects directly from raw HTTP data, supporting incremental parsing for streaming scenarios and chunked transfer encoding. The package is actively maintained, supports Python 3.9 through 3.14, and carries no known security vulnerabilities.","worth_installing":"Yes, with conditions. Install if you are running Gunicorn in a high-throughput environment where HTTP parsing is a measurable bottleneck and you can test compatibility with your specific platform and Gunicorn version. The package is actively maintained, permissively licensed, and has no known vulnerabilities, but its beta status and young release history (first release March 2026) mean production adoption should be preceded by performance testing and staging validation. Avoid if you need guaranteed long-term stability or support for niche architectures without a C compiler."},"id":"gunicorn-h1c","links":{"html":"https://skillfed.io/packages/gunicorn-h1c","md":"https://skillfed.io/packages/gunicorn-h1c.md","pypi":"https://pypi.org/project/gunicorn-h1c/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-04-20","license_spdx":null,"license_treatment":"permissive","name":"gunicorn_h1c","python_support":"supports_current","summary":"Fast HTTP/1.1 parser for Gunicorn using picohttpparser"},"popularity":{"monthly_downloads":128058,"position":11721,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.6.5"}
