Unlimited Spawners
by xokem
Unlimited Spawners lets monster spawners keep spawning mobs without the player staying nearby, removing the vanilla activation range limit.
What it does
Upgraded monster spawners keep working when no player is within the vanilla activation radius, so spawning does not depend on proximity. The server is the only place the mod has to be installed for its changes to take effect. Players who join a server running it need nothing extra. Files are published for Forge and NeoForge across 9 release versions, 1.20.1 – 1.21.4, under a Creative Commons Attribution Non Commercial Share Alike 4.0 license, and the mod is not open source.

What the author says
Installing the mod on the server alone provides all functionality. If clients do not install the mod, they will not be able to see that spawners are still active when outside of the vanilla activation radius, even though the spawners will still be functionally unlimited.
