cfmlFiddle - Compare ColdFusion, Lucee, and BoxLang Side-by-Side - I built a local CFML playground that runs 10 engines at once

cfmlFiddle is a self-hosted CFML playground. It runs on your machine through CommandBox. You write code in an Ace Editor, pick an engine &#x28;or all of them&#x29;, click Run, and see the output. If you picked multiple engines, you see all the results stacked, side by side, or tabbed.
