COPRA onset in it's initial release was running on OSX using XAMPP as a web server package.
With the current version we've switched to the Docker virtualization platform. It has the advantage to run on a wide variety of operating systems - from macOS, Windows & Linux to more specialized solutions like Unraid - and being easier to administrate: If you need to move the COPRA server from one machine to another, simply shut it down, move the whole container (= install folder) to the new location / machine and start it up.
You can find the detailed installation instructions here.
