(ignoring distinction between ColdFusion the commercial product and CFML)

Invision's backend is ColdFusion. ColdFusion still has a ton of use in government, healthcare, etc. It's certainly declined in popularity, and is definitely losing the stickers-on-Macbooks metric, but there are definitely areas where it's still relevant.

This is not ColdFusion (a product owned by Adobe). This is a FOSS engine that implements a modern spin on one of the the web's most mature JVM languages. Lucee Server contains many additional features configuration options, and focuses on the ECMA-like scripting language that is nothing like the old templating syntax.
