Jasob is intended to obfuscate your JavaScript and CSS projects, which means modifying their structure in a way that deters deciphering the code. Fortunately, it supports a long list of languages, including not only those already mentioned but also HTML, ASP, JSP, and XML. The program has a nice and intuitive interface; yet, this is obviously not the kind of software that anyone can use.

The tool does not allow editing the source code; however, it does let you analyze it. In this respect, it can highlight the code for a better understanding of the syntax, which is crucial if you intend to customize the obfuscation. It is also useful that, when you import a project, the program shows a list of all the files that make up the project. Likewise, it can effectively identify and display functions and variables in specific panels. Then, you can change the names of those elements selectively or let the program do the job for you by automatically generating new names.

The program has an excellent performance as it can do its job without using many system resources and practically no time. However, for longer projects, it is possible to adjust CPU usage to avoid interfering with the system’s overall speed. To protect the integrity of the original code, the program does not allow overwriting the source files. Instead, you should save them with new names.

In fewer words, Jasob can successfully protect your projects from code theft by making them very hard to understand. The product is shareware, which means it can be evaluated at no cost. However, as it usually happens with software intended for programmers, its price may be a little too high.
