Lightstreamer is the leading push server for live data distribution to "zero-install" clients, based on the Comet paradigm (also known as "Streaming AJAX" or "AJAX Push"). Lightstreamer Server is able to deliver any real-time data to any browser, enhancing the AJAX paradigm with True Push.

The rapid adoption of AJAX and Web 2.0 has meant that Streaming AJAX is finding an increasing number of new application areas, beyond its original use in the finance industry and more recently in gaming and online auctions. A new edition of Lightstreamer, called Moderato and based on a subset of the commercial editions, is now available free of charge, to add push functionalities to any service or product, whether free or commercial.

"Lightstreamer is fully committed to the evolution of AJAX", said Mauro Fantechi, CEO of Lightstreamer, "We have invested in developing a free version, to contribute to the AJAX community, where Lightstreamer provides the natural progression that bridges the gap between AJAX polling and real-time push".

Lightstreamer began over six years ago and has evolved into a very mature and reliable technology that is currently used within mission critical systems. The architecture of Lightstreamer Server features massive scalability, sustaining thousands of concurrent connections without the need for expensive hardware.

"The new free Moderato edition will bring AJAX-based push technology to other application domains, such as online communities (through messaging and presence), sporting, monitoring consoles or any web solution that needs real-time updates", said Alessandro Alinone, CTO of Lightstreamer, "With Lightstreamer Moderato we want to encourage the development of new solutions that will literally push the boundaries of how the Web is currently used".
