Codename One is an open-source cross-platform framework aiming to provide write once, run anywhere code for various mobile and desktop operating systems (like Android, iOS, Windows, MacOS, and others). It was created by the co-founders of the Lightweight User Interface Toolkit (LWUIT) project, Chen Fishbein and Shai Almog, and was first announced on January 13, 2012.^[3][4]

Codename One built upon the LWUIT platform abstraction by adding a simulator and a set of cloud-based build servers that build native applications from the Java bytecode.^[5]
