Gunicorn vs OpenResty: What are the differences?
Developers describe Gunicorn as "A Python WSGI HTTP Server for UNIX". Gunicorn is 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 resources, and fairly speedy. On the other hand, OpenResty is detailed as "Turning Nginx into a Full-fledged Web App Server". OpenResty (aka. ngx_openresty) is a full-fledged web application server by bundling the standard Nginx core, lots of 3rd-party Nginx modules, as well as most of their external dependencies.
Gunicorn and OpenResty can be primarily classified as "Web Servers" tools.
Gunicorn and OpenResty are both open source tools. OpenResty with 7.12K GitHub stars and 984 forks on GitHub appears to be more popular than Gunicorn with 5.96K GitHub stars and 1.12K GitHub forks.
