PatternNest VS Seamdex

PatternNest's answer

A Rust geometry engine compiled to WebAssembly runs the layout calculations in browser workers. The interface is written in TypeScript, and a service worker supports offline use after the initial load. Pattern files are processed locally on the user's device.

PatternNest's answer

PatternNest combines fabric-length planning, grain-direction rules, cut-on-fold placement and pattern-matching constraints in a local browser tool. It works from existing SVG, DXF and supported vector PDF outlines. Fold edges and pattern reference points are selected explicitly, and the cutting layout can be exported as PDF, SVG or DXF.

Seamdex's answer:

Seamdex is built for textiles, not adapted to them. One garment record, imported from a purchase order, becomes the Digital Product Passport, a GS1 QR code for every size and colour, and the EPR filing, live the same day at one published price.

PatternNest's answer

It suits people who already have digital pattern outlines and want a focused way to compare fabric widths, plan folded fabric or match a repeating print. Up to 10 finished pieces are free, and larger layouts use a EUR 14 one-time licence. Files stay on your device. It handles cutting-layout planning rather than replacing a full pattern-drafting, grading or garment-simulation suite.

Seamdex's answer:

You can start today, you know the full price before you talk to anyone, and the product was built for garments from the first line. Most tools in this space quote an onboarding project, hide pricing behind a demo call and adapt a generic passport to fashion.

PatternNest's answer

Pattern designers, makers and small sewing businesses working with digital pattern outlines, plus home sewists using supported vector PDF, SVG or DXF patterns. The main use is estimating fabric length and preparing layouts when fabric width, piece quantities, fold requirements or print matching differ from a supplied cutting plan.

Seamdex's answer:

Small and mid-sized fashion and textile brands that sell in the EU and want Digital Product Passports and EPR data without an enterprise budget or an implementation project.

Seamdex's answer:

Seamdex started from one observation: the facts about a garment already exist, but brands type them again for every label, retailer sheet and compliance file. As the EU began asking for more of exactly that data, we built one record that feeds every output.
