ZK users report an average of 4-16 times of productivity boost. How is it possible? With ZK's server-centric architecture and ready-to-use 200+ components and themes, you can focus on developing your business logic at the server-side and leave everything else such as server-client communication, browser compatibility, networking, security, and even styling to ZK!
Since our first release in 2005, ZK has been the leader in the industry: we are the 1st Java framework supporting MVVM pattern, the first PC+Mobile responsive solution that supports write once run everywhere, the first client+server fusion architecture, and the first web spreadsheet component…. Innovation is the driving force that differs us from everyone else and motivates us to be better and better each day.
We believe open source is the best way to build an open, secure, and trustworthy software that millions can depend on. ZK CE is freely available under the LGPL license, for both open source and commercial projects. Meanwhile ZK EE with advanced features and professional support are available for mission critical projects.
