## What it is
Waitress is a production-quality pure-Python WSGI HTTP server for Python 3 with no dependencies beyond the standard library. It supports HTTP/1.0 and HTTP/1.1 and runs on CPython (Unix and Windows) and PyPy.

## Use cases
- serve a WSGI app in production
- run Flask or Pyramid behind a pure-Python server
- deploy Python web apps on Windows
- replace gunicorn where C extensions are unavailable
- test WSGI applications locally over HTTP

## When to choose
- you need a dependency-free, pure-Python WSGI server
- you deploy on Windows or PyPy
- you want a stable, production-proven server for WSGI apps

## When to avoid
- you need ASGI/WebSocket support for async apps
- you need maximum throughput from a C-based server like gunicorn or uvicorn

## Facets
- artifact type: library
- maturity: stable
- function: http-server, web-framework
- domain: web-development, backend
- platform: python, windows, cross-platform
- tags: wsgi, pure-python, production-server, linux, macos
