Ender IO

Ender IO is a tech mod created by CrazyPants. A compact tech mod known for its conduit system that allows multiple types of transport in a single block space. As a tech mod it concentrates on machines, automation, and resource processing, and it has been downloaded around 75 million times, which puts it among the options players reach for in this space.

Ender IO is built for players who want machines, conduits, and storage from one cohesive mod. Its signature feature is bundled conduits, letting power, items, fluids, and redstone share a single block-space instead of separate pipe runs. It rewards a bit of learning, so expect to spend some time understanding its systems before they click.

The mod is available for Forge and NeoForge, so it fits a range of modpacks and launchers. It currently targets Minecraft 1.20.1. It runs on both the client and the server, so on a multiplayer server every player who connects needs it installed alongside the server itself.

Ender IO works particularly well alongside EnderCore and Just Enough Items. It depends on EnderCore, so those must be present and on the same loader and version. It targets the Forge side of the ecosystem, so it fits comfortably into Forge and NeoForge packs.

Ender IO has a modest footprint for what it adds and is widely used in modpacks without notable performance concerns.

If you are comparing options, similar mods include Thermal Expansion and Mekanism. They cover comparable ground, so the right choice usually comes down to your loader, version, and the rest of your pack.
