Factory API Mod is a technical mod by developer Wilyicaro. It is used to simplify and speed up the development of custom mods. For the average player, this means that it is a library mod, and it needs to be installed alongside another mod that requires it. Some mods that depend on Factory API include Factocrafty and Better Furnaces Reforged.

Features:
- UI Definitions, to add or modify countless elements of the screens and GUI, either using resource packs (main function) or by code
- Essential Events, most of them abstracting directly from the mod loaders
- A Common Network, to send and register payloads in a unified way, requiring almost zero changes between the supported versions
- Several common implementations among modloaders of item, fluid and energy storage with the correct exposure for the respective APIs
- A way to have block lighting levels with access to Level (only implemented in Fabric, Forge and NeoForge already have this)
