Launch DateJanuary 1, 2008

Laszlo Webtop, the Web 2.0 Desktopâ„¢, provides the industry’s fastest path for delivering multiple Web 2.0-based RIA applications that seamlessly interact across popular browsers and devices. Now in version 1.2, Laszlo Webtop is available in bundled solutions for three target markets: service providers, enterprises and developers. The wide-ranging appeal of Laszlo Webtop makes it ideal for internal or consumer-facing corporate deployments, varying from financial dashboards to consumer communications consoles to enriched enterprise portals. Laszlo Webtop is already serving a number of leading service providers, including Verizon, who recently adopted Laszlo Webtop for its enhanced Webmail offering.

Built on OpenLaszlo, Laszlo’s premier open source platform, Laszlo Webtop allows for multiple OpenLaszlo applications to be integrated into a unified browser-delivered desktop, or ‘webtop’. Webtop also provides advanced data management facilities that are important in larger, more-complex applications. The new complementary set of features and functions that Webtop provides take OpenLaszlo to another level of productivity, efficiency and value for enterprises and service providers looking to establish their leadership in the next generation of web applications. From a developer’s standpoint, Webtop allows for simple integration of OpenLaszlo-based applications using XML for existing applications. Java-based applications need only to implement a simple interface that allows for the exchange of XML data. Other applications can be integrated using forwarding of XML requests over HTTP or other mechanisms.
