Cebus is a C++-based web server and content engine. Although primarily intended as a uniform platform for in-house projects, its architecture and features may be of interest to other developers.

Cebus fills broadly the same niche as Apache or nginx but with a deliberately limited scope, in the name of efficiency and tidiness:

In other ways Cebus's design is fairly standard. It is essentially a servlet container, with libraries and modules providing the usual features: TLS connections, sessions and users, static content, etc. Output is organized through a flexible layout system, with connecting and common code in HTML5, with standardized CSS hooks.
