As answered by people managing Project Euler and Stitchmate.
Stitchmate's answer:
Competitors are either dated desktop apps frozen in 2005 (PCStitch, WinStitch) or basic free tools with clunky interfaces and mediocre output.
Stitchmate offers modern, fluid editing that feels like Figma—instant response, smooth at any zoom level. It works fully on mobile, not just desktop.
And the conversion algorithms are smarter: automatic confetti reduction, perceptual color matching to real thread brands, real-time preview as you adjust.
Stitchmate's answer:
Three things:
Stitchmate's answer:
Cross-stitch enthusiasts who want to turn personal photos—pets, portraits, landscapes—into charts they'll actually enjoy working. Pattern designers selling on Etsy who need professional exports and clean conversions without wrestling with legacy software. Mobile-first crafters who want to design on their iPad or tablet.
Stitchmate's answer:
Built out of frustration with existing tools that feel stuck in the Windows XP era—slow, clunky, desktop-only. The goal: software that respects both the craft and the crafter, with world-class performance, algorithms designed around what makes a design satisfying to work, and a mobile experience that doesn't compromise.
Stitchmate's answer:
React, TypeScript, Canvas2D/WebGL2 hybrid rendering for 60fps performance, Web Workers for background processing, Vercel hosting, Supabase for cloud storage.
