features

Everything a handoff needs. Nothing it doesn’t.

Six things, done well. Built for the dev-to-design handoff, not the demo reel.

Color extraction

We pull every brand-meaningful color, classify primary, secondary, accent, surface, and text — and write hex, RGB, and HSL.

rgb · hex · hsl

Typography analysis

Detected font families, weights, and sizes resolve into a clean, ratio-based type scale your team can actually use.

modular scale

Component detection

Buttons, inputs, cards, and nav patterns are identified and documented with their states and structural specs.

buttons · forms · cards

Accessibility audit

WCAG AA / AAA contrast checks on every text–surface pair. Failures are flagged with the contrast ratio.

WCAG 2.2

Print-ready PDF

A 19-page document with cover, table of contents, sections, and an index — formatted for screen and A4 print.

A4 · letter

Under 60 seconds

Crawl, classify, render, paginate. Average run takes 47 seconds. Long tail capped at one minute.

how it works

Three steps. One minute.

01

Paste a URL

Drop in any public site. We crawl the homepage and one level deep, render with a real engine, and capture computed styles.

GET /analyze → 200
02

We classify

Tokens get clustered, named, and ranked. Type collapses into a scale. Components are detected by shape, not selector.

tokens: 142 · roles: 7
03

Download a PDF

Stable URL at stylesnap.sh/r/<slug>. Open it, share it, print it. Re-runs replace the file at the same link.

/r/9kR2vH.pdf

questions

Things worth asking.

Yes. No card, no account, no paywall. If StyleSnap saves you an afternoon, tips at s3labs.com keep it running — but nothing is gated.
Any public website that loads without authentication. We render the page in a real browser, so SPAs, lazy-loaded fonts, and CSS-in-JS all work. Behind a login or VPN — not yet.
Most runs finish in under 60 seconds. Average is 47 seconds. Heavy SPAs can push toward the cap.
The PDF is final. We're working on an editable HTML output and a token export (JSON, CSS variables, Tailwind theme) — both planned for v1.1.
We cache the rendered output for 24 hours so re-downloads are instant, then it's purged. The PDF stays at its slug forever.
Each guide gets a 6-character Base62 slug — e.g. stylesnap.sh/r/9kR2vH. Not indexed, not listed. Shareable means shareable on purpose.
