## What it is
Gunicorn is a Python WSGI HTTP server for UNIX using a pre-fork worker model, broadly compatible with WSGI and ASGI frameworks like Django, Flask, and FastAPI. It offers multiple worker types (sync, threads, gevent, ASGI), graceful process management, and beta HTTP/2 support.

## Use cases
- serve a Django or Flask app in production
- run a FastAPI ASGI application behind nginx
- deploy a Python web app in Docker
- handle concurrent requests with async gevent workers
- gracefully reload a Python web application without downtime
- serve Python web apps on UNIX with a lightweight server

## When to choose
- you need a battle-tested production WSGI/ASGI server for Python on UNIX
- you want simple, lightweight deployment behind nginx
- you need flexible worker types (sync, threaded, async) for different workloads

## When to avoid
- you need a Windows-native server (Gunicorn is UNIX-only)
- you want a fully-featured internet-facing server with keep-alive for direct exposure rather than a proxy in front
- you need stable HTTP/2 support (still beta)
