No Mob Leaders
by SyntaxFree
No Mob Leaders is a Fabric server mod that removes the leader bonuses vanilla applies to some zombies during a raid-style spawn.
What it does
Some zombies spawn as leaders with large health pools and reinforcement bonuses. No Mob Leaders strips those hidden attribute modifiers, including the leader bonus, the zombie bonus, and the reinforcement caller and callee chance modifiers, so affected mobs keep only their base stats. The changes are read from the server configuration, and the file can switch each bonus on or off on its own.
Selection works through mob entity tags, and the configuration accepts tags written as namespace:tag names. Server owners pick the individual bonuses to switch off and the mobs they apply to, while everything else keeps its vanilla behavior. Only the server needs the mod, and it works in singleplayer worlds, where the host runs the server internally.
Installation needs Fabric API. No Mob Leaders is server-side only, so players join without installing anything. Files are published for Fabric alone, across 17 release versions 1.21 – 26.3, under the MIT License, and the source code is public.
Key features
Configurable leader removal
Leader zombies can be stripped of their bonuses in whole or in part, with each bonus controlled separately.
Attribute modifier stripping
The leader bonus, zombie bonus and reinforcement modifiers are removed from affected mobs without touching their base attributes.
Entity tag selection
Mobs are picked by entity tag using namespace:tag syntax, so a configuration can target specific groups.
Per-bonus toggles
Each hidden bonus can be disabled independently, so a server can keep some leader behavior and drop the rest.

What the author says
A small percentage of zombies spawn as "leaders," granting them massive bonus health pools and high reinforcement spawn rates (no wiki page dedicated for leaders afaik, but here's one for zombies). No Mob Leaders strips these hidden bonuses.
