Pergola Perfect 3D Planner

About

Pergola Perfect is a free 3D pergola planner for DIY builders: you configure dimensions, shape (rectangle or L-shape with a wing extension), lumber sizes, rafter spacing, slat walls, material and foundation, and watch the structure update live in 3D. It instantly generates a complete bill of materials, cut list and step-by-step assembly guide — with real per-item pricing, and shareable build URLs. Built with Three.js and React Three Fiber, it adds engineering-aware conditional logic: minimum beam/rafter sizes, automatic lumber upgrades for larger spans, and frost-line footing-depth warnings. It's a polished, genuinely useful indie tool rather than a brand storefront — monetised through retailer affiliate links.
