Aaron
by aaronhowser1
Aaron is a library mod for Forge and NeoForge that other mods use to reduce duplicated code, and it adds shared utility functions of its own.
What it does
Aaron collects helper code that other mods depend on. Its packet helpers, screen and menu utilities, fake player improvements and codecs are offered as a common set, so an author who needs them does not have to write them again. Four catalog mods list Aaron as a requirement, among them Genetics: Resequenced, Irregular Implements, Excessive Utilities and Superior Crafting Frame.
The mod requires Kotlin for Forge, which must be installed alongside it on Forge. Aaron runs on client and server, so the server and every player need it. Builds are published for Forge and NeoForge, covering 1.20.1, 1.21.1 and 26.1, and the code is released under the GNU Lesser General Public License v3.0 only, which makes it open source.
Key features

Better fake players
Improvements to fake player handling for mods that need automated actors in the world.
Extra codecs
Additional serialization codecs that mods can use when reading and writing their data.

Use cases
Mod authors
Developers who ship a mod that needs packets, menus or codecs can depend on Aaron instead of copying that code into their own project.
Who it’s for: Mod developers building on Forge or NeoForge, and players who install mods that already list Aaron as a requirement.
