I've used ExtJs and jQuery and I can happily say that I have finally grasped Ext after a good few months - be patient, it really is worth it, feels exactly like building with lego.

Both have their uses and both are very powerful. You could do the same thing with jQuery as you could with ExtJs but in order to be more efficient (and have a faster application) you'd probably be better off coding in pure Javascript anyway.

I would also add that ExtJs is quite slow, you just have to take a look at their own documentation, made with ExtJs, and realize it can be everything but fast. And lately this is becoming quite important for SEO. While you can do impressive things with ExtJs, if you start from zero, it will take much time, more or less the same time to build those things with jQuery if you know jQuery a little bit. And with ExtJs will allways run slower. I don't know if that time learning extJs is worth it. Of course the choice is allways yours, and I might lack some good things about ExtJs which make it an awesome library. Couldn’t agree more!

Is the best possible combination! I really tried to use only one or other, but when I saw that the size of the code I wrote is bigger than JQuery size, I simply added it to my project, and I have the best of two worlds!

Jquery is simple, intuitive and easy to understand. You mostly deal with only one object in jquery, called the jquery object. You can use your existing html/css knowledge to your advantage. Extsjs has a steeper learning curve. For example, you have to learn a dozen of javascript classes in the library before you set your foot on a pleasant journey. Jquery allows you to create your view in html/css and then add behavior using javascripts (read view and controller) whereas in the extjs world, view and behavior are somewhat combined. Depending on the nature of your application this could be a virtue or otherwise. So I would say that jquery is less obtrusive. Since jquery allows you to create the views in html/css and add behavior, it allows fine grained control on your presentation. Extjs is more prescriptive in this regard which can be good thing or not depending on your background and viewpoint. Using jquery-UI theme you can provide a consistent look and feel of your website. Using the theme-roller application you can create your own theme or use an existing one. Extjs has a large set of widgets and provide sophisticated layouts out of the box. It has an impressive array of widgets for displaying data in different formats and has support for templating. In jquery world, you will have to code such layouts on your own or use suitable plugins. However, jquery has such a good ecosystem that you will, almost always, find the plugin you are looking for. There are also some significant differences how jquery and extjs are typically used with server side frameworks. Jquery is integrated very easily with popular server side framworks like symfony, cakephp, ASP.NET MVC and ruby on rails. You may have to do some work to integrate extjs with these frameworks as these frameworks do not provide out of the box integration for extjs. Lastly Jquery is free and extjs is GPL licensed and commercial version of extjs costs $329 or more. In the end both are mature and good javascript libraries. - Indra Here are the differences between jquery and extjs in my opinion.

No offense, I agree that ExtJs Has a HUGE selection of widgets, but all the trouble it couses to perform the simplest tasks?? Is it worth it? jQuery Rocks! Best regards! You must be barking mad!!!

Recently, I found an interesting product named ZK Light. UI looks great (similar to ExtJS but not as good as; IMO) and can be designed in XML (a big plus in term of maintenance). Best of all it is LGPL. But, it seems be at the early stage. Anyone has experiences about it? ExtJS switching to GPL is killing me these days. Recently, I found an interesting product named ZK Light.
