Level Prototyper

Level Prototyper is a single-file level prototyping tool for 2D and 3D games.

Open level-prototyper.html in your browser — no install, no server, no dependencies. Block out a greybox level, check circulation, preview in WebGL, then export to your engine.

Built for prototyping

• Fast plan (X-Z) + side section (X-Y) blockout
• Strong snapping and ~25 procedural parts (stairs, ramps, roofs…)
• Livability checks so the prototype is actually walkable
• WebGL 3D with lights, shadows, gizmos
• Export ▾ — JSON, GLB, OBJ, PNG
• Engine packs — Godot (.tscn + colliders), Unity (GLB + collider importer), Unreal (GLB + collider JSON)
• Optional AI assist (bring your own API key)
• English / Turkish UI

Not for

Final art, animation, or a full materials/painting pipeline — refine the export in Unity, Unreal, Godot, or Blender.

Package

• level-prototyper.html
