3D Dungeon Generator review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

3D Dungeon Generator is a free browser-based tool from LevelRift Labs for game prototyping, game jams, and related 3D workflows. It procedurally places rooms and connects them with corridors, while adjustable dungeon dimensions, room count, room sizes, and corridor width give creators control over the generated layout. The tool runs without signup and supports perspective, top-down, and first-person walk views for inspecting a result.

Its strongest feature is the combination of repeatable generation and solvability. Users can set a seed to recreate layouts, and the generator produces connected entrance-to-exit dungeons. Optional solution-path display and export help communicate how a map can be traversed. Built-in themes add starting points for visual direction, while custom wall, floor, and ceiling texture uploads allow the generated spaces to match a project’s look. Real-time 3D preview makes it possible to review changes directly in the browser.

The product is particularly suited to fast dungeon iteration where a browser workflow and GLB-compatible 3D pipeline are enough. GLB export supports moving the resulting model into GLB-compatible 3D workflows, but the published export format is narrow, and the tool’s focus stays on procedural dungeon creation rather than a wider range of map types. Choose it for quick, repeatable 3D dungeon layouts, seeded experimentation, walk-through previews, and straightforward export. Choose another tool if your workflow requires offline access, broader map-generation formats, or export options beyond GLB.

3D Dungeon Generator pros and cons

• Where it wins
  • Procedurally generates connected entrance-to-exit dungeon layouts
  • Seeded generation recreates layouts for repeatable iteration
  • Exports GLB models with optional solution paths
• Where it doesn't
  • Web-only access may not fit offline workflows
  • GLB is the listed export format
  • Focused on dungeon layouts rather than broader map types
