Our Original Work & Tools

All interactive web tools, algorithms, scanner user interfaces, and custom calculation engines on BrickFinder are proprietary original software developed for the building community:

  • Visual ID & Batch Bounding Engine: Real-time camera integration and pile image multi-part detection.
  • Technic Gear Mesh Solver: Gear ratio matrix calculations and center-to-center stud spacing solver.
  • MOC Substitution Engine: Geometry-preserving alternative part matching algorithm.
  • Set Weight Discrepancy Analyzer: Gram scale variance calculation for sealed/missing set verification.

Third-Party Catalog Data

To maintain complete accuracy, part reference data, element numbers, and set inventories are synchronized with permitted public catalog datasets:

  • Rebrickable API: Public set inventories, part relationships, and category definitions.
  • LDraw 3D Library: Open-source 3D CAD mesh geometry and stud dimensions.
  • Official LEGO Design Molds: Standard Design IDs stamped physically on plastic elements.
  • BrickLink Reference Palettes: Community color names, hex swatches, and historical year ranges.
