+# gunicorn
+
+Python WSGI HTTP server. runs Python web apps (Flask, Django) in production.
+
+**role in the deploy chain:** [[Cloudflare]] → [[AWS Lightsail]] → [[nginx]] → gunicorn → Python app. gunicorn manages worker processes, handles concurrency, and speaks WSGI. [[systemd]] keeps it alive.
+
+**why gunicorn:** simple, reliable, zero-config for basic deployments. `gunicorn app:app` and you're running.
