Gunicorn 'Green Unicorn' is a Python WSGI HTTP Server for UNIX. It's a pre-fork
worker model ported from Ruby's [Unicorn](https://bogomips.org/unicorn/) project. The Gunicorn server is broadly
compatible with various web frameworks, simply implemented, light on server
resource usage, and fairly speedy.

**New in v25**: Per-app worker allocation for dirty arbiters, HTTP/2 support (beta)!

## Quick Start

```bash
pip install gunicorn
gunicorn myapp:app --workers 4
```

For ASGI applications (FastAPI, Starlette):

```bash
gunicorn myapp:app --worker-class asgi
```

## Features

- WSGI support for Django, Flask, Pyramid, and any WSGI framework
- **ASGI support** for FastAPI, Starlette, Quart
- **HTTP/2 support** (beta) with multiplexed streams
- **Dirty Arbiters** (beta) for heavy workloads (ML models, long-running tasks)
- uWSGI binary protocol for nginx integration
- Multiple worker types: sync, gthread, gevent, asgi
- Graceful worker process management
- Compatible with Python 3.10+
