## What it is
httptools is a Python binding for Node.js's fast HTTP parsers (llhttp and http-parser), providing request/response parser classes and a URL parsing function. It is a framework-independent library designed for building high-performance HTTP servers and protocol tooling.

## Use cases
- parse http requests in python fast
- build a high-performance http server in python
- parse http responses from raw bytes
- parse urls into structured components
- handle chunked transfer encoding and http upgrades
- replace slow pure-python http parsing in an asyncio server

## When to choose
- you need maximum HTTP parsing speed in Python (e.g., uvicorn-style servers)
- you want callback-driven incremental parsing of streaming HTTP data
- you need framework-independent HTTP protocol utilities

## When to avoid
- you just need an HTTP client or full server framework rather than a low-level parser
- you prefer pure-Python code without C extension dependencies
- you need HTTP/2 or HTTP/3 support

## Facets
- artifact type: library
- maturity: stable
- function: parser, http-server, developer-tools
- domain: web-development, backend, apis, performance
- platform: python, cross-platform
- tags: http-parser, llhttp, binding, cython, asyncio-friendly
