Case studies: extract design systems from live sites
1. Agency competitive UI audit
Problem: A product design team needs a side-by-side token view of three competitor marketing sites before a rebrand workshop. Screenshot decks lose exact spacing and radius values.
Workflow: Open each site → run CSS Design System Extractor → export Markdown + Design Tokens JSON → drop into a shared folder. In under an hour the team has comparable palettes, type scales, and spacing steps instead of eyeballed Figma frames.
Outcome: Workshop starts from real computed styles. Engineers reuse the same JSON as a baseline for Style Dictionary later.
2. Startup Tailwind theme migration
Problem: A frontend squad is rebuilding a legacy marketing site in Tailwind and needs a theme that matches the live reference, not a loose approximation.
Workflow: Extract the live page → preview Tailwind export → download the config snippet →
merge into tailwind.config. Colors and spacing land as theme keys instead of one-off arbitrary
values.
Outcome: Theme authoring drops from multi-day DevTools copy-paste to a single extract plus cleanup pass. Pro unlock ($29 once) pays for itself on the first migration.
3. Designer → Figma Variables handoff
Problem: Design wants Figma Variables that match production CSS, but eyedropper sampling drifts across breakpoints and hover states.
Workflow: Extract with dual light/dark sampling when available → export Figma Variables / import plugin pack → import into the design file → align naming with engineering tokens.
Outcome: Design and code share one vocabulary. Optional AI insight (BYOK) summarizes the design language after extract — your API key, not a billed credit pack.
