This page has a table of web sites that allow code to be executed from a web interface.
These sites were online at one point, but have since vanished with no forwarding address. If you know of online, existing archived copies, please link to them. Also, Rosetta Code may be interested in hosting static copies of such sites where they're at risk of disappearing. Having such content disappear is counter to the goals of this site.
If a site is listed in this section, but is actually still live, please move it back to the live section.
