Process

How It Works

Four steps between you and a fully updated mods folder.

01

Upload Mods

Drag & drop your mods folder, pick files, or upload a ZIP. Files are read locally — nothing is ever uploaded to our servers.

02

Auto-Scan

We hash every JAR and look it up on Modrinth automatically. You'll see each mod identified in real time.

03

Pick Version

Choose which Minecraft version to target. The highest available version is pre-selected. See per-mod compatibility at a glance.

04

Download & Play

Get your updated mods.zip. Drop it into .minecraft and click Replace Folder. That's it.

Features

Why Moddator?

Built for real Minecraft players who maintain large mod packs.

100% Private

Your mod files never leave your device. Only SHA-512 hashes are sent to Modrinth — a public API with no account needed.

Lightning Fast

Concurrent processing scans up to 4 mods simultaneously. A 20-mod pack is identified in under 10 seconds.

All Major Loaders

Fabric, Forge, Quilt, and NeoForge — switch loaders between sessions with one click.

Always Up-to-Date Versions

Dynamically discovers new Minecraft releases — including 1.21.5 and beyond — directly from Modrinth data.

FAQ

Questions

Is this free?

Yes, 100%. It uses the open-source Modrinth API. Ads help keep the lights on.

Do my files leave my device?

No. .jar files are hashed locally in your browser. Only the hash is sent to Modrinth to look up version info. Your actual mod files stay on your machine.

Why does a mod show "Not Found"?

Some mods aren't on Modrinth (OptiFine, paid mods, obscure mods). They're flagged and included in the output ZIP at their current version unchanged.

Why is a version greyed out?

If a mod has no release for that Minecraft version on Modrinth, it's marked unavailable. It'll still be included at its current version.

Do I need an API key?

No. The public Modrinth API works without one. Adding a key boosts rate limits — useful for 50+ mod packs. Get one free at modrinth.com/settings/account.

Which loaders are supported?

Fabric, Forge, Quilt, and NeoForge. Pick yours before uploading — only compatible versions are shown.

Can I go back to a previous step?

Yes! Every step has a Back button and the wizard navigation bar at the top. You can change your folder or loader at any time.

What Minecraft versions are supported?

From 1.4 all the way to the latest 1.21.5+ and 1.22. New versions are picked up automatically from Modrinth data — the list is never stale.
