3D stair calculators in your browser

About

I spent several years designing wooden staircases at a manufacturing company. The process was tedious — especially for standard stairs where you're just repeating the same calculations. So I started building tools to automate it. Stair-Tech is a set of browser-based 3D stair calculators. You set the floor height, number of steps, stair width — the 3D model updates instantly. Change materials, add railing, check 2D plans from different angles.
