About

Lùmen is a native macOS app for hobbyist laser engravers. Connects to GRBL diode lasers from Sculpfun, Atomstack, Ortur, NEJE, and TwoTrees over USB. Image engraving with 7 dithering algorithms, SVG cutting, dual-layer projects, material presets, and a clean SwiftUI interface that feels at home on a Mac. The Mac-first alternative to LightBurn: €9.99 one-time, no subscription. Built by an indie dev who got tired of running Windows VMs to drive his Sculpfun.
