What they say about ZK

“Using ZK, our three developers wrote a system in twelve weeks that a team of eight outsourcing developers had been trying to write for eighteen months.”
- Simon Massey, VP of Global IT, Marsh Inc.

“Could an undergraduate intern develop the UI for an entirely new module for our largest Java application entirely on his/her own?
VERDICT: Yes, within a week”
- Richard Holland, Tech Lead IT, DreamWorks Animation L.L.C.

“This is unlike other frameworks that expose you to the painful details of making Ajax calls. Additionally, Ajax calls require extensive use and knowledge of JavaScript for manipulating the Document Object Model (DOM) on the browser (client) and synchronizing data during client/server communication. ZK shields you from these complexities and lets you focus on the business logic.”
- Sachin K Mahajan, Software Developer, IBM

“We are impressed with your technology... I am expecting that we will be a pretty active participant in this respect.”
- Jan-Fredfrik Birkelund, Sr. Manager, Sun Microsystems, Inc.

“In the last weeks a team of security experts tested a my ZK application. They said that my application is definitely the most secure of the entire company. So congratulations, you are doing a really good job.”
- Tommaso Fin, InfoCert

“In all honesty, ZK seems to be absolutely amazing, very rich, very fast, very flexible, etc. In my opinion, it is probably THE BEST AJAX framework on the planet, by a LONG shot.”
- Trenton D. Adams, Systems Analyst, Athabasca University

“We really recognize and appreciate your innovation and superb work on this project. ZK is simply an amazing platform… Credit must go to the amazing ZK team. Our tricked user interface is mostly done using your API. We like what you have built.”
- Justin Barota, Software Architect, Pitney Bowes

“One thing I like about ZK is the simplicity and flexibility - you don't have to do much and it just produce the result that you wanted; and you can always tweak it if you want to.”
- Romen , GWT vs. ZK – SLOC Count

“Congratulations. Your product is wonderful... after evaluating many choices, we've decided to invest in developing many applications using ZK, both for internal, and citizen use.”
- Gabriel Buades Rubio,
Direcció General de Tecnologia i Comunicacions, Govern de les Illes Balears

“Con la sua capacità di supportare tutti i maggiori browser, di poter essere utilizzato con Java ME Phones, Google Android, BlackBerry, i suoi 3 anni di vita, oltre 1.000.000 di download, dozzine di clienti che fanno parte di "Fortune 500", ZK si candida a essere uno dei prodotti più innovativi nel mondo delle applicazioni RIA che merita sicuramente attenzione e studio.”
- Michele Mazzei, ZK, un semplice e potente web framework basato su Ajax, Mokabyte

“None of this would have been possible, or look near as good without the ZK framework. This is a shining example of what an open-source project should be.”
- Brendan Smith, Open Management and Network Intelligence System

“Yes, zk is the best in most ways. To us, we find ZK allows us to put in our best possible Design in place to build scalable and robust web applications”
- Raja Nagendra Kumar, TejaSoft

“This is a mature and impressive Ajax-based framework… This approach gives developers a great degree of freedom to use powerful techniques... This framework allows for very rapid application development, as the XML mark-up typically replaces a lot of code and the framework lends itself well to reuse.”
- Andre van der Schyff, Senior Developer, DVT

“From time to time I take a look at SourceForge.net projects to see what's active. This speculative browsing has resulted in the discovery of gems such as FileZilla, GAIM, and most recently ZK.”
- Guy Bowerman, Senior Software Engineer of IBM

“I've experimented with most of the AJAX frameworks that have come out over the last year and ZK lives up to its marketing line of, "Simple and Rich".”
- Max Kiesler, Strategic Desinger
co-founder and principle of Ideacodes

“Overall the framework is a joy to use. The ZUML makes it easy to do quick iterations -- edit, test, edit, etc. -- without a long compilation step. The ZUML is also easy enough so that non-programmers can compose or modify a UI. Exposing effects such as drag-and-drop, async update, etc., as components or attributes further eases the development of complex user interfaces for non-programmers and programmers alike.”
- Dietrich Kappe, Chief Technology Officer of Pathfinder

“The ZK site provides excellent documentation. I think you will find it worth your while to experiment with ZK and learn how to build Ajax web applications with minimal effort.”
- Michael Klaene, Senior Consultant of Sogeti LLC

“A really simple Ajax Framework. Needs only basic HTML knowledge. You can give it a try.”
- Cagdas, StumbleUpon

“ZK is one of the best XUL tool for Java that I've known. It's a very powerful framework working on server-side to render DHTML with Ajax capability.”
- Chanwit Kaewkasi, CK's Blog

“Es gibt auch ein nettes Live Demo, wo man ein bisschen was sehen kann... Mit dem TryMe button kann man nicht nur den Quelltext der einzelnen Beispiele sehen, sondern auch gleich mal direkt ändern und live ausprobieren... sehr genial... Das Forum ist sehr aktiv und man bekommt schnell Antwort von den Entwicklern...”
- Thomas Müller, Oberinspector

“Very interesting project for the JAVA developers, that could be very helpful to develop advanced AJAX applications, and the use of XUL make it much more powerful in my opinion.”
- Hatem, Ajax Magazine

“ma evidenziano come ZK sia uno degli strumenti migliori nel mondo Web 2.0: la sua facilità di apprendimento e di uso, la sua notevole flessibilità e la possibilità di essere integrato con JSF, di funzionare anche sui palmari e di disporre di complicati componenti Ajax pronti all’uso ne fanno sicuramente un ottimo strumento da tenere in considerazione.”
- Michele Mazzei

“La caractéristique de ZK est de combiner Ajax pour l'interactivité et le langage de description d'interface XUL (comme Mozilla FireFox et Thunderbird) pour l'utilisation des composants prêts à l'emploi et non propriétaires. ZK dispose de son langage de balisage ZUML permettant de concevoir des interfaces utilisateurs comme une page HTML, sans programmation.”
- Pierre Tran, LeMondeInformatique.fr

“データベースアプリケーションがgrailsコマンド一発で構築できる時代なんだから、リッチなUIだって簡単に作りたい。ZKはそんな希望に応えてくれるWebアプリケーションフレームワークだ。本稿では、ZKが提供するUI作成ツールZK Designerを紹介する。”
- 富田陽介, MYCOM

“GUI的美观程度至关重要，怎么办呢？思前想后，决定使用Ajax技术，但我们也知道，如今Ajax的框架多如牛毛，我该选择哪一个呢，通过 Google找到了ZK。在看完她的在线演示后，被她华丽的外观，简洁实现方式所吸引。于是，就这样，我一边看着ZK技术手册，一边上路了。”
- 牛秀元, Technical Consultant of BEA

“Grazie alle sue potenzialità e caratteristiche uniche gli utenti sperimentano la stessa interattività delle applicazioni desktop, e anche per lo sviluppatore la realizzazione di un'applicazione diviene semplice come creare un normale programma per pc.”
- Antonino Salvatore Cutrì, Programmazione.it

“ZK seems more flexible and it's based on several interesting technologies, like XUL. I believe both (GWT and ZK) can have success.”

- dukeherc, Cofradia

“ZK, uma engine de eventos baseada em AJAX incluindo componentes XUL, XHTML e uma linguagem markup para facilitar a criação de aplicações internet ricas sem a necessidade de programação em JavaScript. Licensiada sob GPL, a ZK consiste em um conjunto de servlets e filters em uma aplicação Web que trata requisições a arquivos. zul.”
- Vitor Fernando Pamplona, Javafree.org

“I was experimenting with different frameworks in order to find something that would boost the productivity within our company’s development team...
