Hi HN! I'm the developer of Jigsaw Designer.
I built this because I saw how painful it was for makers to manually draw puzzle paths in Illustrator/Inkscape—it literally takes hours to get the interlocking tabs right. I wanted a tool that could do this in seconds.
Tech Stack: It's a native macOS/iPadOS app written in Swift and C++.
Core Algorithm: The puzzle generation is powered by a custom C++ engine using Voronoi diagrams and Bezier optimization to create organic, non-repetitive shapes.
Rendering: Highly optimized generic C++ geometry converted to native SVG paths.
Output: The generated SVGs are strictly optimized for laser cutters (LightBurn, Glowforge) with clean, continuous paths to minimize cutting time.
I'd love to hear your feedback, especially if you are into laser cutting or puzzle design! Happy to answer any technical questions.
