our call

Start with Zakeke — highest vibe code, weakest moat.

Sizekick

Building a rule-based questionnaire size guide takes a weekend. Reconstructing 3D body measurements from 2D mobile camera feeds with GDPR-compliant biometric privacy controls requires specialized computer vision engineering.

you can rebuild

  • Interactive PDP size guide overlay modal
  • Form-based user size recommendation (height, weight, age, fit preference)
  • Storefront analytics dashboard for sizing widget interaction rates
  • CSV ingestion interface for brand garment measurement charts
  • Dynamic fit advice callouts (e.g., 'Runs small, order one size up')

what you lose

  • Smartphone camera video/photo 2D AI body scanning models
  • GDPR-compliant biometric data pipeline that auto-deletes raw user images
  • Cross-brand body measurement and actual garment return outcome models
  • Automated garment spec parsing from pattern design files and CAD tech packs
  • Integrated 3D body visualization models for end-users

real moats

  • Proprietary computer vision models trained on 3D body scans and sizing outcomes
  • GDPR biometric compliance framework for handling customer imagery
  • Database connecting actual garment specs across brands to real human body dimensions

Zakeke

Building a simple 2D canvas preview with Cursor is easy, but Zakeke delivers cross-device WebGL rendering, mobile WebXR AR tracking, and CMYK vector print outputs. Rebuilding this requires specialized 3D graphics engineering rather than simple full-stack glue code.

you can rebuild

  • Simple 2D canvas text and logo placement
  • Basic 3D model viewer with rotation and zoom
  • Product variant price adjustments based on selected options
  • Saving customized configuration image preview to cart item attributes
  • Basic color swatch material selectors

what you lose

  • Native mobile WebAR visualizer without app installations
  • Real-time AI camera tracking for facial and body Virtual Try-On
  • Automated production-ready CMYK export files (PDF, SVG, DXF) with exact dimensions
  • Pre-built integrations with major Print-on-Demand providers
  • Automated CAD/GLTF 3D model compression and LOD optimization pipelines

real moats

  • Cross-browser, cross-device WebGL and WebXR camera pipeline handling
  • Battle-tested vector and raster engine for high-resolution print file rendering
  • High switching costs from hours spent mapping UV textures per product catalog item
