Ink/Stitch vs SewWhat-Pro

Ink/Stitch is a machine embroidery design platform built around Inkscape and SVG, available as an extension for Linux, macOS, and Windows. It requires Inkscape 1.0.2 or higher and is free to use under GNU GPL version 3.0 or later. Designs can use running, bean, ripple, satin, fill, cutwork, redwork, and tartan stitches, with manual stitch placement also available. Lettering tools support typing with pre-digitized fonts or creating custom fonts. Users can preview an animated stitch-out or a stitch plan, then make a PDF with realistic rendering or line-drawing mode. Thread tools allow installation of palettes from more than 60 manufacturers, creation of custom palettes, and matching design colors to a selected palette. Ink/Stitch imports and exports embroidery formats including DST, EXP, JEF, PEC, PES, VP3, and XXX, and can export a detailed PDF view. It offers appliqué tools, vector import, and stitch simulation, but not auto-digitizing. Brother PEC and PES files cannot save more than 255 color changes.
