SmartClient from Isomorphic Software
SmartClient is the cross-platform AJAX GUI system chosen by top commercial software vendors, on-demand service providers, and enterprise IT developers for thousands of deployments since 2000. SmartClient provides a complete application stack, from rich, skinnable, extensible GUI components to declarative databinding and SOA integration, paired with a mature, searchable documentation suite and integrated tooling. SmartClient AJAX applications run on Internet Explorer, Mozilla, Netscape, Firefox, and Safari web browsers, on Windows, MacOS, Linux, and Solaris.
