Idle Generators
by Ghozix
Idle Generators is a Fabric and NeoForge storage mod in which placed generators keep producing resources in real time, including while the player is offline.
What it does
Craftable block generators produce items passively over real time, with a live HUD showing how full each storage is. A generator keeps working while the world is closed, so a player can place one, walk away and return to full storages. The mod suits survival worlds such as skyblock, where a steady resource income replaces constant mining.
Each generator's recipe can be changed in the Recipe Editor by picking ingredients in a crafting grid, or by editing a small data pack by hand. The mod also ships 69 unique generators across six sets: Minerals, Wood, Stone, Construction, Colors and Nature, plus Nether. Recipe files are named after each generator, and a file with the same name replaces the built-in recipe, so recipe updates from the mod never overwrite changes. Architectury API, Cloth Config API and Fabric API are required. The mod is published for Fabric and NeoForge, for 1.21.1, 26.2 and 26.3, and the latest builds are 1.5.0 for 26.3, released 2026-09-29.
Key features
Offline generation
Generators keep producing resources while the player is playing elsewhere or the world is closed.
Live storage HUD
A heads-up display shows how full each generator's storage is while the player is nearby.
Withdraw by click
Right-click takes one item, shift with right-click takes a full stack of 64, and breaking the block drops the whole buffer.
Recipe Editor
An in-game editor lets the player choose the Minecraft version and the ingredients for each generator's recipe.
Cloth Config options
Settings are exposed through Cloth Config, and conditions in the config can still turn a generator off.
