LiveCode | LiveCode Server Guide
The LiveCode Server is an interpreter for LiveCode scripts that is started from the command line (does not offer any graphical user interface) and is intended primarily as a CGI processor (this way, web pages can be processed with LiveCode - thus, you do not necessarily have to learn PHP any longer).
LiveCode | Create apps for multiple platforms. Quickly. Easily. Free
LiveCode is a development environment for both stationary (Windows, Linux, MacOS X) and mobile (iOS, Android) applications modeled after the legendary Apple HyperCard. A visual editor allows fast design of user interfaces, a programming language inspired by the english language allows even non-professional programmers to develop professional applications and the concept of "modifying a running program" simplifies testing and troubleshooting.
