Mob Management/Spawn limiter?

I tried looking about before and saw one thread that seems to have been long abandoned; looking to get a plugin that limits how many mobs spawn at a given time, and most preferably designed with compatibility for the project worlds plugin so the configurations can be unique to certain worlds. The goal behind this is to be able to limit the amount of spawned hostile mobs even on easy difficulty as i feel my server tends to spawn a lot of mobs at any given time and I’d like to modify that depending on the world(s) I create.
