Pick Aura if…

You also work in Unity, or you want an agent that launches the game to test its own changes rather than stopping at code.

Pick Ludus AI if…

You want whole-project context for Blueprints, VFX and behavior trees, you approve each change before it lands, and you'd rather your code isn't used for training.

Our verdicts

Aura

Works in both Blueprints and C++, and can launch the game to check its changes instead of stopping at code. Since absorbing Coplay it covers Unity too. One catch: the unlimited Auto Mode requires you to allow training on your chats.

Ludus AI

A plugin that reads your whole project, so its Blueprints call your own classes and sounds instead of placeholders. You approve each change before it lands. The free account has no credits, so plan on the trial or a paid plan.
