waitress-serve is a production-quality WSGI server for Python web applications, implemented entirely in pure Python with no C extension dependencies. It serves frameworks like Flask, Django, and Pyramid and runs on any platform including Windows, Linux, and macOS.
The server uses a multi-threaded architecture with a configurable number of worker threads to handle concurrent requests. It accepts connections on a TCP port or Unix socket and supports URL prefix configuration for applications mounted at sub-paths behind a reverse proxy.
Waitress is designed to be simple and reliable for production deployments, requiring minimal configuration while providing solid performance. It is commonly used behind a reverse proxy like Nginx for static file serving and SSL termination.
