http://www.sarmal.com/sardalya/Download.aspx 不错！速度快!有hint控件。75k. free for non-commercial
http://openrico.org 感觉好像不错，也比较小，这个侧重于远程客户端抓取，不过也有控件！而且可以和wForm联动。 不过它的网格控件比较弱，不支持键盘。 License Rico is provided free and open-source (Apache 2.0 License) for either your personal or commercial use.
http://dojotoolkit.org/ 不错，功能挺全的，但是它的核心js文件有128k，然后还要动态装入其它的js, 太大！！速度慢！！ dojo.js 是它的核心(128K)，然后其它widgets是根据需要装载，所以在使用的东西太多的情况下显得慢。 dojo.js: Dojo's bootstrap system provides some fundamental behaviors, including a package system for dynamically loading scripts. The Dojo Toolkit is only one of the projects that the Dojo Foundation hosts. In addition to the toolkit, OpenRecord calls the Dojo Foundation home.
http://www.htmli.com 不错，速度快！！不过需要客户端的XSLT的支持！幸好的是IE和FireFox1.5都支持！！ 嘿嘿，才发现它的lib.js 居然有189k！但是速度一点不慢！ HTMLi (HTML improved) is the open source framework that focuses in: * Transparent use for HTML designers * Multi-platform: As it is 100% designed with XSL, it is 0% platform-dependant * CSS Themes, Multi-Language support * Fully customizable extensible * XML Rich Forms allow simple AJAX interfaces 俺的选择！俺认为使用客户端处理 XSTL 是速度提升的关键，而且这样一来， html代码扩充显得很自然。
JsRia - Javascript Rich Internet Application (since 2005) [3] JsRIA is a opensource framework enabling rich client interface development. It's pure javascript and is completely independant of the server side technology. The client interface is described by an xml file (or dynamically in javascript if you need that). JsRIA is completely object oriented (javascript components, xml description, css style) and you can very easily build a hierarchy for your interface objects. You also can use AJAX technology to bring really dynamic interface to your users. Numerous functions are provided to parse and use xml flux coming from your server.
http://qooxdoo.org/ 速度慢！！但是控件漂亮！！只适合于Intranet,它的js高达几百k(qooxdoo-0.5.2-build.tar.bz2)，不过qooxdoo-0.5.2-source.tar.bz2,中是拆分成若干js的！！ qooxdoo (Under development; from May, 2005) qooxdoo is an advanced open-source JavaScript-based GUI framework. It helps you to implement AJAX-enhanced web 2.0 applications - easier than ever before.

Google Web Toolkit Google Web Toolkit (GWT) 是一个Java软件开发框架用于开发类似于Google Maps和Gmail 的AJAX应用程序. 你可以用Java编程语言开发你的界面,然后用GWT编译器将Java类转换成适合浏览器执行的JavaScript与HTML. 主页 http://code.google.com/webtoolkit/
