How do I install ServiceIO?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on Modrinth — not every file is mirrored on our own servers.

What Minecraft version does ServiceIO work with?

The listing gives Minecraft 1.21.3, 1.21.4, 1.21.5, among others. This is the version stated by the author or source site, not something we verified ourselves.

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.

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.

ServiceIO – Full Replacement for Vault

A modern, drop-in replacement for Vault that offers enhanced functionality, better performance, and seamless integration across plugins.

[!NOTE] ServiceIO is designed as a full replacement for Vault, so Vault is no longer necessary when you make the switch. Rest assured, all your existing plugins that depend on Vault will continue to function seamlessly with ServiceIO.

Why should You use ServiceIO?

Full Vault replacement with drop-in compatibility for existing plugins.
Safer and more reliable API with nullability annotations, better docs, and actively maintained code.
Faster, more scalable performance through async data loading.
Seamless migration path: use Vault interfaces and ServiceIO together without extra integration work.
Data conversion for Economy, Permissions, Holograms, NPCs, and more, so plugin switching is easy.
