# Lapas

> Browser-based 2D nesting software for cutting shops. Upload DXF or SVG, get an optimized cutting layout in seconds. Free plan, no install required.

Lapas is a SaaS tool that automatically arranges cut parts on sheet material to minimize waste — a process called "nesting" or "true-shape nesting". It runs entirely in the browser (no download needed), works on Windows, Mac, Linux, and tablets, and offers a free plan with no credit card required.

Built by Rokas Slaboševičius (founder). Operated by Pro Sistemos, MB — a company registered in Lithuania.
