Why UltraGen?

There are many technologies for template engine however all well known mainstream are provided as a package or framework of some language, each one with its own learning curve. Even the response body is treated in a separated method. UltraGen tries to solve this as making the web development part of the language. You don't need to learn the script and the language, since they are all UltraGen. It also ships with a web framework embedded that implement many of developers needs, like cookies, sessions or routes handling. In addition to create web pages UltraGen can be used to process any type of text that has variable data inside a template, like XMLs or config files with some changes.
