At a request from Carl Sassenrath, inventor of REBOL and the Amiga OS, Kaj has created a website that allows you to try the REBOL programming language without installing it. The site showcases the new REBOL version 3 that is close to going into beta release. It also offers to test the classic REBOL 2 and ORCA, the open source implementation of REBOL, and to make comparisons between them.

The website is running on Syllable Server 0.3, in development towards version 0.4. For this application, the security of the server operating system was enhanced to be able to offer the public to run generic REBOL scripts.

The website was made on top of the REBOL stack included in Syllable Server. It runs on the Cheyenne web server. It is made in a Model/View/Controller architecture with the network application platform we have been working on: a combination of the QuarterMaster web framework and the content management system that is also used to build our Syllable websites. This REBOL demo site marks the transition of this application platform to being capable of building advanced interactive websites.
