httptools
A collection of framework independent HTTP protocol utils.
Decision gist · record as of 2026-08-14
Yes. httptools is actively maintained, carries no known vulnerabilities, uses a permissive MIT license, and ranks in the top 1000 PyPI packages by download volume. It is worth installing if you need fast, callback-driven HTTP parsing in a custom framework or protocol handler. The medium install friction (compiled wheels) is standard for performance-critical C-bound libraries and is well-mitigated by pre-built wheels for common platforms.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later; compiled wheels are provided for common platforms but source builds require a C compiler.
- Medium install friction due to compiled wheels for multiple Python versions and platforms.
- The package is actively maintained with recent releases and no known vulnerabilities.

What it is and what it does
httptools wraps the Node.js HTTP parser (llhttp) and http-parser libraries to provide fast, standards-compliant HTTP request and response parsing in Python. It exposes two main parser classes—HttpRequestParser and HttpResponseParser—that accept callback-based protocol objects and emit parsed data through methods like on_url, on_header, on_body, and on_message_complete. It also includes a parse_url function for structured URL decomposition.
The package is designed for frameworks and applications that need efficient HTTP parsing without reimplementing the protocol logic. It has no runtime dependencies and is actively maintained, supporting Python 3.9 and later across macOS, Linux, and Windows platforms. The callback-driven API allows integration into event-driven or streaming HTTP processing pipelines.
Use it for
- Parsing incoming HTTP requests in a custom web server or async framework.
- Extracting structured data from raw HTTP response streams in a client library.
- Decomposing URLs into components (schema, host, port, path, query, fragment) for routing or validation.
- Building protocol handlers that need to detect HTTP upgrade requests or manage keep-alive connections.
- Streaming HTTP body data through callbacks without buffering entire messages in memory.
