Starlib
by Starcatcher
Starlib is a library mod that other mods use for shared code, published for Fabric and NeoForge.
What it does
Starlib works as a shared base for other mods, so authors can call its helpers instead of writing the same code again. Its author notes describe a set of utilities, including tree generators, cobble generator data and a system for falling objects with a list of what falls. The Stargazer mod requires it, so it is installed alongside that mod as well.
Starlib requires Architectury API on both loaders. A server running it needs every connecting player to have it too. Files target Fabric and NeoForge; the latest Fabric build is 1.0.4 for 1.21.1 and the latest NeoForge build is 1.0.4 for 26.2, both published 2026-10-01. The code is under the MIT License and is open source, with public source code available.
The mod was first published on 2026-08-01 and last updated on 2026-10-01. Files exist for 1.21.1 and 26.2, and the game versions 1.21.1 – 26.2 are covered across two release versions. The mod is maintained by its author team.
Key features
Tree generators
Helpers for generating trees can be reused by other mods that need terrain features.
Cobble generator data
Data structures describe how cobble generators produce blocks, so mods can read or extend them.
Falling objects
A falling object system lets mods define blocks or entities that drop under gravity.
Falling objects list
A list of falling objects is kept in one place, so other mods can register entries and look them up.

Use cases
Library for other mods
Mod authors who want generators or falling objects can depend on Starlib rather than copying the code into their own project.
Extending Stargazer
Stargazer requires Starlib, so players who use Stargazer also need it installed.
Who it’s for: Mod developers who want shared utilities for terrain generation and falling objects, and players who run mods that depend on Starlib, such as Stargazer.
How it compares
Ryan'sRenderingLib is a Fabric-only library for client-side rendering, released under the MIT License for 1.17 – 26.3, so it covers rendering rather than generators. Dynamic Asset Generator is open source under the GNU Lesser General Public License v3.0 or later, works on Fabric, Forge, NeoForge and Quilt for 1.18.1 – 1.21.1, and runs on either side. Generic Registry is open source under the GNU General Public License v3.0 or later, Fabric-only for 1.7.2 – 26.1.2, and runs on either side.
