FLIB (FutureLibrary) is a library of shared code for its author's mods, making new mods faster to build and easier to port between versions.
It includes worldgen, dimension and recipe utilities, plus /flib commands such as cross-dimension teleport and health or hunger tweaks, which can be disabled in flib.toml. Runs on Forge and NeoForge for Minecraft 1.18.2 - 26.1.2.
When one of the author's mods asks for it, Minecraft hosting lets you add FLIB with a single click in the panel.
