Assuming server related stuff belongs (in general) in the modding categorey…
How would I go about setting up a dedicated web panel to access my servers and send them basic stuff like STOP, SHUTDOWN, RESTART, SAVE, UPDATE, and of course just direct access to console? And ontop of that, how would I make a login system so only certain people can access certain servers?
You could probably get a login system setup (there’s tonnes of guides) with PHP, then have those commands set up to some kind of relay to the console. TBH you’d be better off hiring someone to make that for you/asking someone nicely.
