For many years, developers have been asking questions about the licensing of Ext JS, the popular JavaScript framework. Recently, there has been a lot of confusion and debate about the licensing of Ext JS, and many developers have been uncertain as to what they can and cannot do with the framework.

To clear up the confusion, I decided to do some research and finally get to the bottom of the Ext JS licensing issue. After months of research, I’m happy to say that I now have confirmation of my doubts about Ext JS licensing.

First, let’s address the most common misconception about Ext JS licensing: that it’s open source. This is simply not true. Ext JS is a commercial product and is owned by Sencha, which is a company that develops and sells a range of JavaScript-based tools.

When it comes to licensing, there are two options available for Ext JS. The first is the commercial license, which allows developers to use the framework for commercial projects. This license is the most expensive option and comes with a wide range of features, including access to tech support, priority bug fixes, and more.

The second option is the Open Source license, which is free to use and allows developers to modify the source code of Ext JS. However, the Open Source license does not allow developers to use the framework for commercial projects.

So, to recap: Ext JS is not open source, but it does come with two different licensing options. The commercial license is the most expensive option and allows developers to use the framework for commercial projects. The Open Source license is free to use, but does not allow developers to use the framework for commercial projects.

My doubts about the Ext JS licensing have been confirmed, and I’m glad that I was able to get to the bottom of this issue. Now, developers can make an informed decision when it comes to deciding which license to choose.
