Fabric per player spawns
by vlad2305m
Fabric per player spawns gives each player their own mob cap on a server, so a crowded spot elsewhere does not stop mobs spawning near a player.
What it does
Vanilla caps mobs across the whole world, so one busy area can use up the cap for everyone. The mod changes the spawn logic so the cap counts the mobs in a square area around each player, sized by the server render distance and the chunks that player has loaded. The default per player mob cap is 70, and the default monster mob cap is changed from the vanilla value, so two players standing apart can each have mobs near them.
When the spawn areas of several players overlap, the most full one applies in the overlapping chunks. Holding a glistering melon while in creative or spectator mode shows the debug information for this. The mod is server-side only, so players join without installing anything, and the server alone runs it. Files exist for Fabric only, and the latest one is 3.2.2 for 26.3, published 2026-09-29. Proper Mobcap Modifier works alongside it.
Key features
Per player mob cap
Each player has a separate mob cap, 70 by default, counted over the chunks around that player.
Account based radius
The counted area follows the server render distance, in the same way vanilla mob caps are tracked.
Overlap handling
Where two players' areas overlap, the more filled cap is the one that applies in those chunks.
Debug view
Holding a glistering melon in creative or spectator mode displays the debug information for the caps.

How it compares
MobCap HUD shows mob caps on the client and is open source under the MIT License, with Fabric files for 1.21.5 – 1.21.11. Simple Mob Switch is server-side only, open source under the MIT License, and has a Fabric file for 1.21.5. PerPlayerWanderingTraders is also server-side only and open source under the MIT License, but it handles wandering traders for each player rather than mob caps.

What the author says
Forked from Lambdacraft because he went afk. I rewired the mixins to work with 1.16.5, and then just rewrote that part of the mod as I see fit.
