DeKaf is a software system for programming and communicating through the internet. It has features similar to internet entities such as the world wide web, Usenet, ftp, and others, but is at the same time greatly simplified yet more powerful.

The Dekaf system consists of five major parts: the browser, the editor, the server, server applications, and the DeKaf programming language. It is designed to be simple and intuitive to use. Additionally, there is a Commercial Code Creator that is used to write commercial DeKaf code for resale.

The core of the DeKaf system is called a capsule. It is a file containing objects, text, graphics, DeKaf code, and other resources. Capsules are self-contained internet "entities".

Capsules are not static. They have some "perception" of their environment, and are capable of communicating and interacting with other capsules, the DeKaf test console, DeKaf server applications, and other internet entities.

Multiple capsules can be "alive" simultaneously in the DeKaf browser, processing and exchanging information between themselves.

Unlike web pages, capsules do not necessarily have to reside on a DeKaf server, they can reside in Usenet. This means that anyone can have web functionality without having to own, lease, or maintain a web server!
