The Hakin9 magazine did a short review of Jasob. You can read it here.

"...We searched around for a solution that would allow us to easily obfuscate our JavaScript objects and Jasob saved the day. Jasob's approach to obfuscation allows us to achieve maximum compression which means less download time for our users. Obfuscation also makes it very difficult for someone to hijack our code and use it for their own purposes. PS: I love the fact that updates are emailed to me as soon as they're released. Thank you Jasob!"

"...Jasob works very well for us! We are using Jasob to protect and compress Javascript code inside our iMacros software for visual Web automation and Web testing. We found Jasob easy to use with a very powerful command line interface, so we can integrate it seamlessly into our build process. Jasob is a great addition to our development toolbox."

"...I personally take a lot of pride in choosing Jasob because I spent a good couple of months scouring the Internet looking for the right one. The reason was because I wanted one that I could use and recommend to others for a long time to come. Since my job involves a lot of JavaScript work obfuscation is incredibly important to me. I looked high and low at every obfuscator you could imagine. I researched everything, from the free ones to really expensive ones and none of them quite fit the bill. Jasob was so impressive that I was rather shocked that the price was so affordable. There were obfuscators that I was reviewing that were priced really high but were so insanely difficult to use that there was no contest when compared to Jasob. I built Jasob directly into my one-step Web deployment installer in a matter of a day. Everything about the interface to the command-line usage made sense, unlike all of the other ones I tried. So as you can see I'm a big fan and I'll be using and recommending this software for a long time. Keep up the great work!"

"...Jasob has been most valuable in the development of BaseCase Interactive. The GUI allowed us fine-grained control of the specifics of the obfuscation, a necessity on our large project. That it could be invoked from the command-line allowed us to integrate it smoothly with our development process, saving valuable time."

"...We have used Jasob for several projects and found it to be an easy to use, effective obfuscator. It is the best value application around with all the functionality we need. Jasob also provide great technical support whenever we have had any questions. Highly recommended!"

"...Our project involves converting our JavaScript source and making sure it works in a wide variety of browsers. We evaluated numerous obfuscators and Jasob was the one that resulted in code that worked without tweaking in all our browsers! It was also easy to setup a batch process to integrate into our development process."

"...The wonderful professionals at Jasob have been very adaptive to our needs, they always listen to what the customer needs which makes them a class organization to work with."
