Custom Software
QSM Web supports using your own server software, however, there is a limitation that it can’t have a separate install process like Forge or NeoForge
To work around that issue, you can run the install process beforehand and import it as a server archive.
This feature can, and will be used for RCE (Remote Code Execution) if not careful. As noted in Security, Do not give anyone you don’t trust access to your server.
