ZK is extendable via plugins, all components are responsive designed, and the framework is secure against common CSRF, DoS and XSS attacks.
Its track record is spotless and the framework has made its way into companies like Sony, IBM, Toyota, Roche, Sun, DreamWorks, eBay, Adobe and the United Nations.
The source code, binaries and development versions are available on SourceForge. Various ZK widgets can be tested via the online demo.
