Unified LEGO layout designer

One browser tool that merges LDD, Studio, and Bluebrick for large LEGO layouts

Problem

LEGO fans designing large layouts must switch between LDD, 4DBrix, Studio, and Bluebrick, with no unified way to handle physical height differences, 2D/3D views, and individual MOCs—the workflow is fragmented.

Solution

A browser-based unified editor that imports common formats, handles 2D top-down and 3D preview on the same canvas, annotates height offsets and module ownership, and exports parts lists.

Users

Large-layout LEGO hobbyists, MOC creators, and LEGO convention organizers

MVP

Import LDraw/Studio files; 2D canvas drag layout with height annotations; 3D preview; export parts list as CSV

Revenue

Free for 3 layouts; $4/month subscription for unlimited layouts and collaboration; $39 one-time

Why now

The adult LEGO community is active but tool fragmentation has gone unsolved for years; WebGL and the LDraw ecosystem are mature enough for a solo dev to lower the barrier via the browser
