About this app

Find a pattern. Follow it deeper. Make it yours.

Fractal Forge is a fractal explorer and generative art studio with more than 1,000 fractals to discover. Travel through Mandelbrot and Julia sets, explore intricate 3D forms, and turn mathematical patterns into art for your screen.

Explore beyond the familiar
• Browse by category or search for a fractal by name.
• Discover Mandelbrot, Julia, Burning Ship, Newton basins, strange attractors, tilings, cellular automata, Mandelbulb and Mandelbox.
• Zoom, pan and rotate supported 3D fractals. Start with a preset or try the randomizer when you want a surprise.

Make the colors your own
• Switch palettes, create your own gradients and adjust fractal parameters in real time.
• Build symmetrical compositions with kaleidoscope effects, or add a text overlay.
• Experiment with your own formulas in Formula Lab.

Keep what you create
• Export PNG images up to 4K for wallpapers, prints and sharing.
• Animate zoom, pan and parameters with Looper, then export GIF loops.
• Save presets so you can return to a favorite look. Share a link that reopens your view.
• Explore Fractal Music and Fourier analysis for another way to experience a pattern.

Your studio, offline
No ads, no account and no tracking. Core exploration and creation work offline. Fractal Forge is free and open source under Apache 2.0.

High contrast, reduced motion, screen-reader labels and adjustable touch targets help you explore your way. Rendering speed and the depth of available zoom depend on the fractal and your device.

Open a fractal. Change one thing. See where it takes you.
