## What it is
Meinheld is a high-performance asynchronous WSGI web server for Python, built on the picoev event loop and greenlet. It can run standalone or as a gunicorn worker, and supports PEP 333/3333 compliant WSGI applications.

## Use cases
- serve a python wsgi app with high performance
- run flask or django behind a fast wsgi server
- use meinheld as a gunicorn worker class
- host a websocket chat app in python
- replace gunicorn's sync workers with an async event-loop server

## When to choose
- you need a fast, lightweight WSGI server on Linux, FreeBSD, or macOS
- you want to boost gunicorn throughput with the meinheld worker
- your stack is Python 2.6+/3.5+ WSGI-based

## When to avoid
- you need ASGI support for async frameworks like FastAPI or Starlette
- you rely on the deprecated websocket or continuation features
- you need Windows support or actively maintained software
- you want long-term support, as the last release was in 2021

## Facets
- artifact type: library

- function: http-server, websocket, middleware
- domain: web-development, backend, apis
