Railo Server, commonly referred to as Railo (/ˈraɪloʊ/ RY-loh), is open source software which implements the general-purpose CFML server-side scripting language, often used to create dynamic websites, web applications and intranet systems. CFML is a dynamic language supporting multiple programming paradigms and runs on the Java virtual machine (JVM).
Railo was created by the Swiss company Railo Technologies GmbH, intended as a high performance alternative to Adobe ColdFusion. In 2008, Railo switched to an open source community-driven model, and became a JBoss project. The Railo Open Source project is led by Railo Technologies, with development work funded by consulting and support contracts, but anyone may contribute code for consideration.
