Connector Extras is a utility mod that adds integration bridges between Connector and third-party APIs, allowing Fabric mods to work seamlessly on Minecraft Forge and NeoForge. It acts as a compatibility layer that resolves API conflicts between the two mod loader ecosystems, making cross-platform mod usage possible without manual patching.
One of the most persistent headaches in Minecraft modding is the divide between Fabric and Forge ecosystems. You find a perfect Fabric mod, but your modpack runs on Forge — and you are stuck. Connector bridges that gap, but many Fabric mods rely on platform-specific APIs that still break on the other side. That is exactly the problem Connector Extras solves. With over 7.9 million downloads since its 2023 release, this companion mod by Su5eD has become an indispensable part of cross-platform modpacks, quietly handling the API translation work that keeps everything running together.
Key Features of Connector Extras
- Team Reborn Energy API Bridge — This module enables two-way conversion between Forge Energy (FE) and Team Reborn's Energy API (E), which many Fabric tech mods depend on. The default ratio is 1 E to 10 FE, and you can configure each direction independently or disable conversion entirely by setting a ratio to zero. This means tech mods like TechReborn can interact with Forge-side machines without energy systems breaking.
- REI Plugin Platform Bridge — Roughly Enough Items is one of the most popular recipe viewers in Minecraft, but its Fabric plugins do not load on Forge by default. This bridge runs REI's Fabric plugin detector alongside the Forge one, so recipe plugins from both platforms load simultaneously. You get a complete recipe browser without needing to hunt for Forge-specific alternatives to every REI addon.
- EMI Plugin Platform Bridge — Similar to the REI bridge, this module allows EMI's Fabric plugins to load on Forge. EMI has gained significant traction as a recipe viewer, and this bridge ensures that Fabric-side EMI plugins register correctly on the Forge platform, keeping your item browsing experience intact across loader boundaries.
- Reach Entity Attributes Port — Several Fabric mods depend on the Reach Entity Attributes library for extended player reach mechanics. The original version causes heavy mixin conflicts on Forge, so Connector Extras provides a clean Forge port that works alongside Forge's own reach attributes. Combat and interaction mods that rely on this library can now function without crashing your game.
- Architectury API Bridge — Architectury is a popular abstraction layer that many cross-platform mods use internally. This bridge registers Fabric mod event buses to Architectury on Forge, preventing registry initialization errors that would otherwise cause mods to fail silently or crash during startup.
- TerraBlender Bridge — Fabric mods that add custom biomes often use TerraBlender for worldgen integration. This module makes their TerraBlender calls work with the Forge version, so biome mods from the Fabric ecosystem can generate their terrain correctly in your Forge-based worlds.
- Forge Config API Port Bridge & ModMenu Integration — Fabric mods that use the Forge Config API Port can now access the actual Forge config system directly, while ModMenu's config screen factory integrates with Forge's mod list GUI. This means you can configure Fabric mods through the standard Forge interface instead of manually editing config files.

How to Install Connector Extras
- Download and install Minecraft Forge for 1.20.1 or NeoForge for 1.21/1.21.1, depending on your Minecraft version.
- Install Connector, as Connector Extras is a companion mod that requires it to function.
- Download the correct Connector Extras file for your Minecraft version and mod loader from the download section below.
- Place the downloaded
.jarfile into your.minecraft/modsfolder. If the folder does not exist, launch the game once with your mod loader to generate it. - Launch Minecraft and verify that Connector Extras appears in your mod list. Install any additional bridge dependencies (such as REI, EMI, or Architectury) as needed for your specific modpack.

Pros and Cons
Pros
- Solves critical API compatibility gaps that Connector alone cannot handle
- Modular design lets you use only the bridges you need
- Configurable energy conversion ratios for fine-tuned tech mod balance
- Open source under MIT license with active development
- Over 7.9 million downloads — well-tested across thousands of modpacks
Cons
- Only useful if you already use Connector — not a standalone mod
- Some bridges require the target mod (REI, EMI, etc.) to be installed separately
- Cross-platform compatibility can still have edge cases with complex mod interactions
- Forge support limited to 1.20.1; newer versions require NeoForge
Alternatives to Connector Extras
- Connector — The core mod that bridges Fabric mods to Forge and NeoForge. Connector Extras extends its functionality, so you need Connector as a base regardless.
- Architectury API — A cross-platform abstraction layer that mod developers use to write code compatible with both Fabric and Forge from the start, reducing the need for runtime bridges.
- Forgified Fabric API — A Forge-side implementation of the Fabric API that allows many Fabric mods to run on Forge without individual compatibility patches.

Frequently Asked Questions
Do I need Connector installed for Connector Extras to work?
Yes — Connector Extras is a companion mod that extends Connector's functionality and will not work without it. Install Connector first, then add Connector Extras to enable the additional API bridges for third-party mods.
Does Connector Extras work with NeoForge?
Yes — Connector Extras supports NeoForge for Minecraft 1.21 and 1.21.1. For Minecraft 1.20.1, you should use the Forge version instead, as NeoForge builds are not available for that older release.
Can I use only some of the bridge modules?
Yes — Connector Extras is designed with a modular architecture. Each bridge only activates when its target mod is present. If you do not have REI installed, for example, the REI Plugin Platform Bridge simply does nothing and adds no overhead.
Will Connector Extras affect my game performance?
The mod appears to be lightweight since it primarily handles API translation during mod initialization rather than during gameplay. The bridges register event handlers and energy conversion at startup, so the runtime impact during actual play is minimal for most users.
Is Connector Extras compatible with both REI and EMI at the same time?
No — you should use either REI or EMI, not both simultaneously, as they serve the same purpose and can conflict. Connector Extras provides separate bridges for each, so whichever recipe viewer you choose will have its Fabric plugins loaded correctly on Forge or NeoForge.
