Gunicorn 'Green Unicorn' is a Python WSGI HTTP Server for UNIX. It's a pre-fork worker model ported from Ruby's 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
pip install gunicorn
gunicorn myapp:app --workers 4
For ASGI applications (FastAPI, Starlette):
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, eventlet, asgi
- Graceful worker process management
