Simply Java
ZK is renowned for "Ajax without JavaScript", enabling developers to build rich Web applications without any knowledge of Ajax and JavaScript. In addition, with programs executed at the server, developers can leverage all the Java technologies, such as Java EE and Spring, while back-end data and services are readily available.
Enterprise-level Security
With ZK all business logic is stored at the server meaning increased security for Enterprise applications. No business logic is ever exposed to the client, protecting you from XSS, CSRF, DOS and OWASP Top 10 Security Concerns.
Innovative Technology
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.
