Compat API

by FixerLink1 · on CurseForge

Universal compat api that auto-loads integrations, data packs and loot modifiers for mods that depend on it. Free Minecraft Java mod for 1.21.1, 1.20.1.

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.

Mod loader

Minecraft version

⬇ Download for 1.21.1 · Fabric⬇ Download for 1.20.1 · Fabric⬇ Download for 1.21.1 · NeoForge⬇ Download for 1.20.1 · Forge
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.

📖 About

Compat API is a lightweight and universal compatibility framework for the entire “Compat” ecosystem by fixerlink — including Compat Delight, the upcoming Compat Artifacts, Compat Decor, and any third-party mod that wants an easy, automated way to add cross-mod integrations.

Instead of hardcoding compat logic or manually managing data packs, Compat API handles everything for you: auto-loading compat code, injecting data packs, wrapping loot modifiers, applying conditions, and enabling integrations only when the required mods are installed.


📃 Features


📝 Description

How it works:

You install Compat API. That’s it.

If a mod depends on Compat API and includes compat modules, the API will:

If the target mod is missing — the compat simply won’t load. No errors, no crashes, no manual setup needed. Mods can freely add compat folders and classes — Compat API does all the heavy lifting. And of course, every integration can be toggled via config.


🎁 Bonus Info


🧾 Credits

Compat API is developed by fixerlink as a universal standard for all Compat-series mods and for developers who want clean, modular, and automated cross-mod integrations.
