What Mekanism works with.
| Platform | Java Edition |
|---|---|
| Loaders | NeoForge, Forge |
| Minecraft versions | 1.7.10, 1.10.2, 1.11.2, 1.12.2, 1.15.2, 1.16.5, 1.18.2, 1.19.2, 1.20.4, 1.21.1 |
| Environment | Client, Server |
Mekanism is a Minecraft Java mod for Forge and NeoForge that replaces simple smelting with tiered machinery, multi-step ore processing and transport networks for items, fluids, gases, energy and heat. It is required on both the client and the server. Forge releases run from 1.7.10 to 1.20.1, NeoForge releases from 1.20.1 to 1.21.1.
What Mekanism adds
The mod has no single goal. Core features such as energy cubes and factories use four tiers (basic, advanced, elite, ultimate). Players upgrade a component in a crafting grid with the needed resources, or in the world with tier installers.
- Ore processing: purification, dissolution, chemical injection and crystallization can return up to five ingots per ore, given enough infrastructure and energy.
- Factories: any machine can become a factory that processes 3, 5, 7 or 9 items at once, depending on tier.
- Digital Miner: automated mining with filtering.
- Jetpacks: hydrogen-powered, with several togglable flight modes.
- Robit: a robotic companion that follows you around.
- Logistical Transporters: item networks that sort and filter.
- Refined Obsidian Armor: a near-indestructible suit, available later in a playthrough.
Loaders and supported versions
- NeoForge: 1.20.1 to 1.21.1. The newest release is 10.7.19.85, dated 2026-04-10.
- Forge: 1.7.10 to 1.20.1. The newest release is 10.4.16.80, dated 2025-05-21.
- Fabric and Quilt: no releases.
- Side: required on both client and server.
The trade-off is plain. Forge releases stop at 1.20.1, so 1.21 and 1.21.1 need NeoForge. Older releases list different optional extras than the newest one.

Questions about Mekanism.
5 questions
How do I install Mekanism?
Install Forge or NeoForge for the Minecraft version you want, put the Mekanism file in .minecraft/mods, and launch with that loader's profile. No other mod is required. Do the same on the server, since Mekanism is needed on both sides.
Does Mekanism work on Fabric?
No. Mekanism has releases only for Forge and NeoForge, and none for Fabric or Quilt. Pick the loader that matches your Minecraft version, because a release only works with the loader it was made for.
Which Minecraft versions does Mekanism support?
Forge releases cover 1.7.10 to 1.20.1, and NeoForge releases cover 1.20.1 to 1.21.1. For 1.21 and 1.21.1 you need NeoForge. The newest NeoForge release is 10.7.19.85, and the newest Forge release is 10.4.16.80.
Does Mekanism work on multiplayer servers?
Yes, but it must be installed on both the server and every client that joins. A server without Mekanism cannot host its blocks and machines for players who have it, so match the loader and Minecraft version on both sides.
Do I need Mekanism Generators?
Not to run Mekanism. The Fusion Reactor does require Mekanism Generators, which is a separate module. Mekanism Additions and Mekanism Tools are also separate, so add only the ones you want.
