OpenLaszlo is a discontinued open-source platform for the development and delivery of rich web applications. It is released under the Open Source Initiative certified Common Public License (CPL). The OpenLaszlo platform consists of the LZX programming language and the OpenLaszlo Server. LZX is an Extensible Markup Language (XML) and JavaScript description language similar in spirit to XUL, MXML, and Extensible Application Markup Language (XAML). LZX enables a declarative, text-based development process that supports rapid prototyping and software development best practices. It is designed to be familiar to traditional web application developers who are familiar with HTML and JavaScript. OpenLaszlo Server is a Java servlet that compiles LZX applications into executable binaries for targeted run-time environments.

OpenLaszlo was originally called the Laszlo Presentation Server (LPS). Development began in the fall of 2001. Preview versions were released to select partners throughout 20021. Several of these were used for the first deployed Laszlo application, for Behr paint. The first general release of LPS was in early 2002. In October 20041, Laszlo Systems released the full source code to the Laszlo Presentation Server under the GNU General Public License (GPL), and initiated the OpenLaszlo project. In 2005, coincident with the release of version 3.0, the name of the Laszlo Presentation Server was changed to OpenLaszlo.
