I've seen speedrunners that have 3 worlds in the corner already loaded, so when they're finished with a run they go to the next one with the press of a button, I assume it's a mod but what mod is it?

It’s not a mod, it’s using multiple instances, join Javacord or specnr’s discord to get more info on it.
