Musterlab Takes Apart the Web’s Design Systems

musterlab.space Observed source

Editorial interest 86/100 Selection signal · not a rating of the site

A searchable library that measures the visual systems behind 1,289 product websites and turns them into usable design references.

Landing page captured for the 2026-09-13 issue.

Field notes

Each entry translates a live website into a structured reference: named color roles, font weights, radius conventions, page dimensions, and plain-language rules. The fastht.ml example specifies six colors, Geist and Geist Mono typography, 9999px pill controls, and a two-layer sticker-like shadow. Musterlab says these references can be copied into DESIGN.md, Tailwind, CSS variables, or token formats for use in code and AI-assisted workflows.
