    Default What are some viable Ext alternatives/competitors?

    Just curious, what right now are some legitimate Ext alternatives and competitors? I was talking with a coworker about my preference for Ext for all things when it comes to RIA's, and he made the remark that "not everything has to be done in Ext." I responded that I didn't know of any frameworks nearly as robust or mature as Ext, and most of the frameworks I've seen consist of a lot of widgety things and none seem capable of doing things like Ext's layout manager does. Thoughts?

    There is no JS framework that can match Ext JS

    I'm interested in the same. We have struggled with performance and memory usage in ExtJS for years, and are about to embark on a replacement effort. We are eyeing up the following so far:

    1. kendoui.com
    2. wijmo.com
    3. a smattering of jqueryui based components

    There is no doubt that none of the options will provide the robust application framework that ExtJS does....but unfortunately we have no choice due to the negative feedback from our customers based on performance/memory.

    There are quite a few "alternatives" mentioned on an older list from StackOverflow:
    "
    1. Mochaui.com looks interesting (moved to github). https://github.com/mui/mochaui
    2. ampleSDK (interesting approach)
    3. DojoToolkit and their nice set of widgets
    4. The always changing jQuery UI
    5. The radical Cappuccino
    6. rialto
    7. A bit rough on the edges Echo
    8. Simple UI kit UKI see demo
    9. vaadin (Requires Java)
    10. jxlib.org based on Mootools
    11. A bit beta, but Prototype-ui
    12. Simpler widgets livepipe.net
    13. dhtmlx.com
    14. HTML5 + MVC sproutcore, see their demo
    15. qooxdoo see widgets
    16. http://www.linb.net/
    "
    #3, #9, #13 #15 and even #16 seem to perform better than ExtJS under some usual "business scenarios" .

    In that list I'd say Dojo is pretty much the only serious competitor if your want a mature web app framework. If all you want is a simple widget framework then there are lots and lots.

    Not a competitor, but it could become one:

    http://scn.sap.com/community/developer-center/front-end

    SAP's toolkit for developing html5 web apps. It's not as bad as you would think, and it doesn't require a server-side component.

    As far as actual competitors, i think dojo is the main one, if you're going for a widgetlike approach. Others are cappucino and Sproutcore. If you're looking for databinding, but can live without widgets, ember.js looks interesting.

    I've looked just a bit at dhtmlx.com and on the surface it seems nearly as powerful as ExtJS. Being such a full featured framework though, I worry about the same performance and memory challenges that ExtJS has. Anyone have any experience with it? This relevant blog post was interesting - http://www.dhtmlx.com/blog/?p=1525

    Also worried about support. Like ExtJS, the only help to be found would be the dhtmlx community itself. jQuery and jQueryUI, on the other hand, is so widely adopted that the internet support is nearly limitless.

    I have to say regardless of how well sencha touch 2 is capable of performing the documentation is just so terrible. It is confusing, not up to date, and as a result i am left with no other choice but to recommend another framework to my clients it has been so long now and yet there are still video tutorials and written documentation that is not even correct at this point. horrible

    About documentation, we have hired new technical writers to keep the guides up to date and also the API documentation. We are taking it seriously to get it back to being the best around.

    Default alternative

    I had make two generator code.. first using extjs 3.3 something and and jquery + twitter boostrap. Both will generated around 1k per form javascript..
    Jquery and twitter boostrap best alternative because of grid only. The most reason data grid.. I'm not sure the latest sencha okay on datagrid more then 500 record.... that's the only my issue changing.
