A screamingly fast, ultra-lightweight asynchronous WSGI server for CPython, written in C using Marc Lehmann's high performance libev event loop and Ryan Dahl's http-parser.
bjoern is the fastest, smallest and most lightweight WSGI server out there, featuring
- ~ 1000 lines of C code
- Memory footprint ~ 600KB
- 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
- Arch Linux
pacman -S libev
- Ubuntu
apt-get install libev-dev
- Fedora, CentOS
yum install libev-devel
- Mac OS X (using homebrew)
brew install libev

For most users, the easiest way to install bjoern is using pip
. Make sure
libev is installed and then:
pip install bjoern
You can also build bjoern by directly using the provided setup.py
file (this
is probably most useful if you actually want to hack on bjoern):
python setup.py install
On some Linux systems (notably Fedora and CentOS), the libev headers may be installed
outside of the default include path. In order to build bjoern you will need to
export CFLAGS
when running setup.py
, for instance:
CFLAGS=-I/usr/include/libev python setup.py install
# Bind to TCP host/port pair: bjoern.run(wsgi_application, host, port) # Bind to Unix socket: bjoern.run(wsgi_application, 'unix:/path/to/socket') # Bind to abstract Unix socket: (Linux only) bjoern.run(wsgi_application, 'unix:@socket_name')
Alternatively, the mainloop can be run separately:
bjoern.listen(wsgi_application, host, port) bjoern.run()
