PatternSoft consolidates pattern design into a single desktop workspace: a local pattern repository, parametric generation powered by FreeSewing, and a visual canvas editor for drawing pieces and applying size grading - with everything stored on your own machine.
PatternSoft is built for home sewers, professional pattern designers, and makers who want to design, adapt, and grade patterns independently - without a cloud subscription. It runs natively on Windows, macOS, and Linux, and every pattern stays on your machine.
A local library for organizing and searching your sewing patterns with metadata.
Integration with FreeSewing to generate patterns based on your own measurements.
Canvas-based tools to draw pattern pieces and apply sizing adjustments by hand.
Output to PDF and SVG for printing at home or sending to a professional plotter.
Native desktop builds for Windows, macOS, and Linux - no browser required.
No account, no cloud sync - your patterns and measurements never leave your machine.
Built with Tauri and React for a small, fast native app. Licensed MIT - free to use, inspect, and modify.
DryTrix builds and maintains PatternSoft, and takes on custom software development work for teams that need it.
