Cross-stitch tools haven't changed in decades — expensive Windows apps and locked PDFs you can't edit. Knytstudio is a free, browser-based pattern editor. Design from scratch, convert photos into stitchable charts with DMC colors, or describe your idea and get a pattern instantly. What's unique: every published pattern can be remixed. Want different colors or a different size? Remix it. It's like open source for craft patterns. No download, no signup required to start.
