SimpleWeb is a Swift module to ease simple CGI web app creation on Linux. The emphasis is on easy and simple. So this is not for creating complex nor huge web apps, but for simple ones. It's more like the Playgrounds for web programming using Swift. :)
The live demo can be seen here: http://cak.lebah.web.id/webtest.cgi
(It's on a free CodeAnywhere container, so it's not always on.)
