NaviServer is a high performance web server written in C and Tcl. It can be easily extended in either language to create interesting web sites and services.

NaviServer is based on AOLserver, AOLs Open Source webserver. The NaviServer project started as a fork (software development) of the AOLserver project. It is different in that it wants the various decision-making processes to be more open and transparent.

The project is under active development, hosted on SourceForge.
