Tntnet is a modular, multithreaded, high performance webapplicationserver for C++. To create webapplications Tntnet has a template-language called ecpp similar to php, jsp or mason, where you can embed c++-code inside a html-page to generate active content. The ecpp-files are precompiled to c++-classes called components and compiled and linked into a shared library. This process is done at compiletime. Because the webapplications are compiled into native code, they are very fast and compact. The webserver Tntnet needs only the compiled componentlibrary. Components can call other components. So you can create buildingblocks of html-parts and call them in other pages like subprocesses.

Snakelets is a very simple-to-use Python web application server. It provides a threaded web server (you don't have to provide a web server such as Apache yourself), Ypages (Python HTML template language, similar to Java's JSPs) and Snakelets: code-centric page request handlers (similar to Java's Servlets). Snakelet's focus is to make the creation of dynamic web sites as quick and easy as possible.
