EasyEntityLib
EasyEntityLib is a Forge library for 1.20.1 that lets developers register custom mobs with a few lines of code instead of writing the full setup by hand.
What it does
Developers call registerSimpleMob to create a basic mob, and the library handles the tedious boilerplate, including attribute renderer registration, behind the scenes. AI, attributes and per-tick logic can be defined directly in the registration call with lambda expressions, so a mob does not need a separate goal setup.
For entities with their own logic, registerAdvancedMob takes custom entity classes. The library also provides a TameableRideableMob base class for vehicles, companions and golems, with taming, riding and a built-in AI goal networking system. Its package is aimed at mod developers rather than players.
The library is published for Forge only, on 1.20.1, and runs on client and server, so both sides need it. The license is Creative Commons Attribution 4.0, and the code is not open source.
Key features
Simple mob registration
registerSimpleMob creates a basic entity from a single call, with AI and per-tick logic given as lambda expressions.
Fluent attributes
A MobAttributes builder sets key stats such as max health, movement speed, attack damage and armor in a readable chain.
Taming logic
A mob is tamed on its first interaction, and afterward only its owner can ride it, which keeps companions secure.
Full rider control
The owner steers the mob's movement, including custom jump and flight logic, through the built-in goal system.

Who it’s for: Forge mod developers who want to add custom mobs, companions or rideable entities for Minecraft 1.20.1 without writing the full registration code themselves.
