Welcome to the bjoern wiki!

A screamingly fast, ultra-lightweight WSGI server for CPython 2 and CPython 3, written in C using Marc Lehmann's high performance libev event loop and Ryan Dahl's http-parser.

Why It's Cool

bjoern is the fastest, smallest and most lightweight WSGI server out there, featuring

• ~ 1000 lines of C code
• Memory footprint ~ 600KB
• Python 2 and Python 3 support (thanks @yanghao!)
• Single-threaded and without coroutines or other crap
• Can bind to TCP host:port addresses and Unix sockets (thanks @k3d3!)
• Full persistent connection ("keep-alive") support in both HTTP/1.0 and 1.1, including support for HTTP/1.1 chunked responses
