You may want to start up a local server that does not have a CF Engine such as Lucee or Adobe ColdFusion installed. You can do this as of CommandBox 5.1.0 by setting the cfengine parameter to none like so:
server start cfengine=none
Or in your server.json like this
server set app.cfengine=none
server start
This server will support everything that you are used to including the server.json file, heap settings, ports, and virtual directories. The only difference is it will server everything as static files. (.cfm or .cfc files will not be processed)
