Download Fabric API

Fabric API is a shared library used by many Fabric mods. It does not replace Fabric Loader. In most setups, you install Fabric Loader first, then place the Fabric API jar and your other Fabric mods inside the Minecraft mods folder.

The safest choice is usually the newest stable release that matches your Minecraft version. Pre-release builds can be useful for snapshots or testing new game versions, but they may change faster than normal releases.

If a mod says Fabric API is missing, check three things: the jar is actually in the mods folder, the Minecraft version matches the Fabric API build, and the game is launching with the Fabric profile rather than a vanilla profile.

Fabric API is a shared library used by many Fabric mods for Minecraft. It provides common hooks, events, registries, networking helpers, rendering helpers, resource APIs, and other foundations that mod authors can build on instead of recreating the same systems in every mod.

If a mod page says Fabric API is required, you normally need both Fabric Loader and Fabric API. Fabric Loader creates the Fabric profile or server environment. Fabric API is the jar file that goes into the mods folder with the rest of your Fabric mods.

This download page is designed for regular players, server owners, and modpack users who want to get the correct jar quickly while still being able to inspect release notes before installing.

The latest Fabric API release is usually the best choice when you are playing the newest Minecraft version or creating a fresh modpack. Newer builds often include compatibility updates, module changes, and bug fixes needed by recently updated mods.

Older versions are still important. Many popular modpacks and servers stay on older Minecraft versions for stability, world compatibility, or mod availability. If your pack targets Minecraft 1.20.1, you should not assume the newest Fabric API build is the right file.

Search for the Minecraft version or release tag shown by your modpack, launcher error, or mod requirement. Version matching is one of the simplest ways to avoid missing dependency errors and startup crashes.

FabricAPI.net was made by Minecraft and Fabric fans to make Fabric easier to discover and install. The page is written in plain language for players who may not be familiar with GitHub releases, Maven metadata, loader profiles, or dependency errors.

The release list is loaded from the public FabricMC GitHub release feed. The jar buttons use upstream release asset URLs, while this page adds explanations, search, changelog previews, and install guidance around those releases.

We keep the official release notes link on every release card so advanced users can verify the original release page. Those external links open in a new tab and use nofollow attributes. FabricAPI.net is not the official FabricMC website and does not claim ownership of Fabric API.

If Minecraft says Fabric API is missing, first check that the jar file is inside the correct mods folder. Many launchers create separate instances, and each instance can have its own mods directory.

If the game crashes during startup, check compatibility between Minecraft, Fabric Loader, Fabric API, and the rest of your mods. A single mismatched dependency can stop the whole profile from loading.

If you are running a server, install server-compatible mods only. Client-only mods should not be placed on a dedicated server unless the mod author specifically says they work server-side.
