OpenLaszlo is the premier open-source platform for rich internet applications.

OpenLaszlo is an open source platform for creating zero-install web applications with the user interface capabilities of desktop client software.

OpenLaszlo programs are written in XML and JavaScript and transparently compiled to Flash and soon DHTML. The OpenLaszlo APIs provide animation, layout, data binding, server communication, and declarative UI. An OpenLaszlo application can be as short as a single source file, or factored into multiple files that define reusable classes and libraries.

OpenLaszlo is write once run everywhere. An OpenLaszlo application developed on one machine will run on all leading Web browsers on all leading desktop operating systems.

Cinematic user experience
Applications developed on OpenLaszlo provide a dramatically improved online user experience featuring advanced interfaces delivered on a single Web page. By bringing true application behavior to the Web, OpenLaszlo makes a new generation of online communications, commerce and content services viable for the first time.

imageRapid XML development approach
OpenLaszlo applications are written in LZX, a standards-driven XML and JavaScript description language that enables a declarative, text-based development process. LZX supports rapid prototyping, collaborative software development and long term code maintenance.

imageScalable deployment architecture
Depending on requirements, OpenLaszlo applications can be deployed either SOLO (Standalone OpenLaszlo Output) or from the OpenLaszlo Server. SOLO deployment supports most use cases and works from any HTTP Web server. OpenLaszlo Server deployment supports additional data integration options, persistent connections and run-time media transcoding. The OpenLaszlo server is Java-based and works with leading J2EE application servers and Java Servlet Containers. OpenLaszlo's standards-based architecture delivers exceptional reliability and scalability, proven in deployments serving millions of users to date.


Develop standards-based rich Internet Applications that support any web browser with a single code base in XML and JavaScript.

Deploy them from any HTTP Web server in SOLO mode, or from a J2EE application server or Java servlet container running the OpenLaszlo Server under Linux, UNIX, Windows or Mac OS X.

Display them in any Web browser enabled with the Flash 6 Player or above, reaching 96% of all Web-enabled desktops.
