Describe a Minecraft mod.
We build and test it.

Ender AI writes Fabric mods for Minecraft 1.21.4 from your prompt, builds them, runs them on a real test server with a bot that verifies the behavior, and iterates until they work. Then it hands you a JAR you can drop into your game.

We'll log you in immediately. No verification email, no card, no fuss. If you already have an account, sign in instead.

1. Describe

Type your mod idea in plain English: "a sword that heals me on hit", "speed boost when sneaking", anything.

2. We build + test

Our agent writes Java code, builds with Gradle + Loom, boots a Fabric server, sends a bot in-game to verify the mod actually works.

3. Download

Drop the JAR in your mods/ folder and play. No coding required.
