Download Cuberta

Version 1.0.0. Free to download and use — no account, no trial, no subscription. The bundled models, materials and skies work offline.

  • Any GPU from the last decade will do — the viewport is WebGL 2.
  • Nothing else to install: both GLB and FBX are written by the app itself.

The first launch asks for a confirmation

Neither build is code-signed yet, so both systems stop an unknown developer once. Nothing is wrong with the file — it is the same one you see hashed below.

  1. Windows

    SmartScreen shows a blue window. Press More info, then Run anyway.

  2. macOS

    Gatekeeper asks once. Right-click the app and choose Open, or allow it under System Settings → Privacy & Security.

What you get

An editor that an agent can drive

A built-in MCP server exposes 58 tools plus readable guides. Any MCP client can connect — Claude Code is just the usual first one.

A starter pack that works offline

CC0 furniture, panoramas and materials ship with the app, so the first scene needs no network at all.

Export that lands in your engine

GLB and FBX come out with textures embedded, axes and units already set for Unity, Unreal, Blender and Godot.

Online catalogs when you want them

Poly Haven and ambientCG need no key. Poly Pizza takes a free key of your own, added in Settings.

System requirements

Operating systemWindows 10 or 11 (64-bit), or macOS on Apple Silicon or Intel
GraphicsAny GPU with WebGL 2 — integrated graphics from the last decade included
AccountNone. The editor never asks you to sign in; signing in is only for your HiGen3D library
AI agentAny MCP client, brought by you, with your own model access
NetworkOptional. Needed for online asset catalogs and for the agent's own connection
Local portThe app listens on 127.0.0.1:7345 and nowhere else

Verify what you downloaded

Because the builds are unsigned, the honest thing is to publish their hashes. Compare the sum of your file with the one for its name here.

Connect an agent

Start Cuberta — the window title reads MCP listening on 7345 when the server is up. Press Copy connect command in the top-right corner and paste what lands on your clipboard into a terminal:

claude mcp add --transport http cuberta http://127.0.0.1:7345/mcp \
  --header "Authorization: Bearer <token>" --scope user

The token is generated on your machine at first launch and stays there. Any other MCP client needs the same URL and the same header.
