Common questions

Is designlang safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: DESIGNLANG_BRAND_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed today, and the latest version (13.4.1) reached the registry today.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Is it generic? (`slop`) and is it on brand? (`verify-ui`)

designlang slop opens the page in a real browser and scores how generic it looks, from 0 (distinct) to 100 (generic), listing each known AI-design tell it found with what was measured and where. Add --brand DESIGN.md to also score how close the page is to your brand. Try it in the browser at designlang.app/slop.

designlang verify-ui --brand checks a screen, localhost included, at phone, tablet and desktop widths and in dark mode. It returns pass or fail, an on-brand score, and every drift with the expected and actual value. It exits 1 on drift, so it can gate CI. Your AI editor can run the same check itself through the MCP tool verify_ui.

Watch it read — live Extraction Theatre (`v13`)

Don't take the output on faith — watch it happen. On designlang.app/watch you paste a URL and a real headless Chromium opens the page and reads its entire design system in real time: a split stage with the live browser on the left and the design system — palette, type, spacing, motion — assembling itself on the right as each token lifts off the page.

It's driven by the *actual* extraction (the browser's CDP screencast streamed frame-by-frame alongside the real token events), recorded so a shared link replays the exact run. No install, no account. Every gallery card can be watched the same way, and the gallery now spans 37 real-graded design systems.

Whole-site design system (`site`)

Most extractors read a single URL. designlang site crawls a site's canonical pages (home, pricing, docs, blog, about, product…) and synthesizes one de-duplicated system. Every token is elected by *coverage* — the share of pages that use it — so what's genuinely site-wide is separated from one-off, page-local choices. Near-identical colours are merged in OKLab. It's fully deterministic and free; no API key.

npx designlang site stripe.com --max-pages 8

You get, alongside the standard pack emitted from the canonical system:

File	What it is
`*-site-system.json`	canonical unified tokens + coverage + drift
`*-site-coverage.md`	every token tagged 🟢 site-wide / 🟡 section / 🔴 page-local, with the pages using it
`*-site-consistency.md`	a 0–100 consistency grade, per-category breakdown, and the off-system outliers to consolidate

Measured clone fidelity (`fidelity` + `gallery`)

Cloning tools all *claim* "pixel-perfect" — none of them measure it. designlang fidelity does. Point it at the original and your clone (often a local dev server) and it returns one honest number, both halves of the clone:

Visual — full-page screenshots of each, pixel-diffed.
Motion — extractMotion() on both, compared across feel, durations, easings, springs, keyframe kinds, scroll-linked motion, and choreography/ stagger. (Most clones reproduce static pixels and drop the motion entirely; this is where they lose.)

The two blend into a 0–100 score + letter grade, and — the part competitors don't ship — a ranked correction plan: the exact next edits that will raise the score, hardest-hitting first. Measure → fix → re-run until it converges.

npx designlang fidelity https://stripe.com --clone http://localhost:3000

npx designlang fidelity https://stripe.com --clone http://localhost:3000 --min 90 # CI gate

Generating the clone with designlang clone? Add --fidelity and it grades the clone's token basis against the live site the moment it's built — writing FIDELITY.md + a correction plan straight into the project, no separate step:

npx designlang clone https://stripe.com --fidelity

You get fidelity.md (score + motion table + correction plan), fidelity.json, a shareable fidelity-card.svg (88% · B · stripe.com), and a fidelity-diff.png loss heatmap.

Then publish them. designlang gallery scans your reports and builds a deployable static site — an index of score cards plus a permalink page per clone (each with an OG card, so a shared link unfurls the number).

npx designlang gallery --title "Our clones" --base-url https://clones.example.com

A measured design space (`dna`)

Every extractor on the market answers *what* a design uses. None of them answers where it sits. designlang grade returns a letter — but a letter with no reference frame is a thermometer with no scale on it.

designlang dna reduces a design to 30 deterministic features across five axes — colour, type, space, shape, motion — and ranks it against a corpus of real design systems:

npx designlang dna raycast.com

  Design DNA · https://raycast.com

30 features, 100% measurable

vs 8 systems (default)

color 65th percentile type 56th percentile space 42th percentile shape 79th percentile motion 67th percentile

Nearest 0.14 https://railway.app 0.15 https://linear.app 0.19 https://notion.so

Distance is the mean absolute difference across the features both designs have, so 0.14 reads as "the average feature is 14% of its range apart" — a number you can reason about, unlike a Euclidean distance in 30 dimensions.

The report goes past similarity to what makes a design look the way it does: the features furthest from the middle of the corpus, in plain language (*"corner radius — 100th percentile, far above the corpus"*).

Bring your own reference frame — your products, your competitors, a target look:

npx designlang dna-corpus acme.com acme.com/pricing competitor.com
