bjoern is an ultra-lightweight, high-performance WSGI HTTP/1.1 server for CPython 2 and 3, written in ~1000 lines of C on top of libev and http-parser. It serves Python web applications (e.g., Flask, Django) with a tiny ~600KB memory footprint and keep-alive support.

Use cases

• serve a flask app in production
• fast wsgi server for python
• lightweight python http server with low memory footprint
• replace gunicorn with a faster wsgi server
• bind python web app to unix socket
• run django behind nginx with a minimal wsgi server

When to choose

• you need a minimal, extremely fast WSGI server for CPython
• memory footprint matters (e.g., containers, small VPS)
• you serve a Python app behind a reverse proxy like nginx
• you want keep-alive and chunked HTTP/1.1 support without heavy dependencies

When to avoid

• you need async/ASGI support for WebSockets or long-lived connections
• you need multi-threading, worker processes, or built-in process management
• you need extensive features like TLS termination, static files, or admin tooling
• you want a batteries-included server like gunicorn or uwsgi
