Is Cuberta free?
Yes. Cuberta is free to download and use on Windows and macOS, with no account, no trial period and no subscription. The bundled models, materials and skies are included.
Which AI agents work with Cuberta?
Any MCP client. Claude Code is the one most people start with, but the app exposes a standard Model Context Protocol server, so anything that speaks MCP can drive the scene. You bring your own agent and your own API access.
What can the agent actually build?
Whole locations — road networks with junctions and sidewalks, blocks of buildings with real facades, terrain, vegetation, street furniture and lighting. It also builds single objects: a house with a furnished interior, a room, a prop. If you can describe it, it will attempt it.
Which engines can I export to?
GLB and FBX come out with textures included, which covers Unity, Unreal Engine, Blender, Godot and anything else that reads glTF or FBX.
Do I need to know 3D modeling?
No. You describe the place in plain language and correct the agent when it goes the wrong way. Knowing your engine's import settings helps more than knowing how to model.
How is this different from Blender MCP?
Blender MCP hands an agent the whole of Blender, which is powerful and slow — the agent spends its turns writing Python against a general-purpose modeller. Cuberta is a purpose-built editor for locations: the tools it exposes are already about roads, buildings, terrain and placement, so the agent works at that level instead of rebuilding it every time.
Does Cuberta work offline?
The editor and its bundled content run offline. The agent itself needs whatever connection your model provider requires, and signing in is only needed to browse your Wandy3D library.
What are the system requirements?
64-bit Windows 10 or 11, or macOS on Apple Silicon or Intel. Any GPU from the last decade will do. The builds are not code-signed yet, so Windows SmartScreen and macOS Privacy & Security will ask you to confirm the first launch.
