Aura vs Ludus AI: which AI agent for Unreal Engine 5?
Both are AI assistants that work inside the Unreal Editor and can build Blueprints and C++ for you. They differ in how they check their own work, what else they cover, and how they treat your data.
| Aura | Ludus AI | |
|---|---|---|
| Best for | An agent that builds, launches and tests its own work | Blueprints, C++, VFX and behavior trees with whole-project context |
| Free option | 2-week free trial. Unlimited Auto Mode requires allowing training on your chats. Source | 14-day trial with a card. The free account has no credits, so the agent needs the trial or a paid plan. Source |
| Price | Indie $10/mo billed yearly ($120/yr, 50% off the $20 list price). 2-week free trial | Pro $25/mo or $20/mo yearly. 14-day trial (card required) |
| Works with | Unreal 5.4–5.8, Unity 2022.3+ | Unreal 5.4–5.8 (Windows, macOS, Linux) |
| Maker | Ramen VR | Ludus AI |

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.
