Mandelbrot Metal is an independent software studio focused on creating breakthrough experiences at the intersection of art, science, mathematics, and high-performance computing. Founded by developer Michael Stebel, the studio pushes the limits of hardware and graphics technologies to build apps that are not only technically advanced but also visually extraordinary.
The studio’s flagship app, Mandelbrot Metal, brings the infinite complexity of the Mandelbrot and Julia sets, and related fractals, to life on iPhone and iPad through high-performance, real-time rendering. Engineered as a showcase for Apple’s Metal® framework, Mandelbrot Metal supports ultra-deep zoom, HDR color workflows, 8K+ exports, 3D visual effects, and more than 155 curated color palettes, transforming abstract mathematics into a precise, immersive visual experience. It climbed to #3 in the App Store’s Paid Graphics & Design category and has remained in the Top 100 every week since its October 2025 launch, consistently charting alongside long-established creative tools.
Mandelbrot Metal is also developing ChromaForge, a new developer-focused color system tool built from the palette technology behind Mandelbrot Metal. ChromaForge is designed to help developers, web designers, app builders, and design-system teams move from beautiful palettes to production-ready color systems, with tools for importing, previewing, repairing, tokenizing, and exporting color into real development workflows. ChromaForge will support iPhone, iPad, and Mac on iOS/iPadOS/macOS 26+. More information.
