Flexible Games Builders Pack

Java modpack listed for Minecraft 1.18–1.21. Downloads from the MC Java Mods app on Android.

The Builders Pack is for those who enjoy building, automation, and design but struggle with the grind of mining.

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

This pack offers many tech-based mods to learn, master, and expand your automation empire. And do so with limited mining grind-work. Build giant reactors to power your ever-growing base, and eventually never need to mine again with RFDimensions and void miners. Focus on building, automating, and designing.

No Create mods at all in MC 1.21.1 version. No Thermal either.
Mekanism, Immersive Engineering/Petroleum, Oritech, Industrial Foregoing, PneumaticCraft, Powah
AE2, Storage Drawers, Sophisticated Backpacks
Draconic Evolution and Infinity Cells for the end-game.
Custom ore-gen across the board, with Void Miners for extra cheese.
A few custom recipes for further grind reduction.
