WIIS
by CoAmazing
WIIS is a server-side Fabric optimization mod that catches unwanted mob spawn attempts before they take place.
What it does
WIIS intercepts mob spawn attempts on a server and cancels those it is configured to stop, which keeps unwanted mobs from appearing. Since it runs on the server alone, players connect without needing to install it. Its published files target Fabric for 1.20.1 and 1.20.2, with v1 for 1.20.2 as the latest build, released under the GNU General Public License v3.0 only and open source.
Key features
Spawn interception
Mob spawn attempts are caught and filtered before the mob enters the world.
Server-side operation
All filtering happens on the server, so connecting clients need no extra files.
Game rule dependency
Operation depends on the relevant gamerules being enabled on the server.

What the author says
The mod works only on the server side. To work with the config in a multiplayer game, you need level 4 permission¹ on the server, and also WIIS must be enabled in the gamerules.
