Unkey — Design System

dark · modern · medium · tailwind · confidence 92% · deep decode

Unkey secures APIs in blackout: Articulat CF at 64px/400 white on #040406, Inter at 16px, and sharp zero-radius white buttons. Rate-limit dashboards and key-verification code samples glow against the void with thin keyline borders — developer security tooling with the visual temperature of a server room at night.

Tokens

Unkey's decoded design system: background #040406, text #9194A1, accent #ABAEBB, link #ABAEBB, primary #9194A1; type scale h1 64px / h2 44px / body 16px; 8px spacing base; 0px base radius. The single interactive/action color is #FFFFFF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #FFFFFF — the single interactive color; only on things you click or must notice, never large fills.
• accent, link are all #ABAEBB — one role, not several (the action color).
• accent #ABAEBB — accent for emphasis — keep it rare on the page.
• primary #9194A1 — ≈ the text color — a foreground/text color, not an action color (action = #FFFFFF).
• secondary #3C83F6 — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.

# Unkey — Design System

> dark, modern, medium, tailwind — deep decode (measured live)

Unkey secures APIs in blackout: Articulat CF at 64px/400 white on #040406, Inter at 16px, and sharp zero-radius white buttons. Rate-limit dashboards and key-verification code samples glow against the void with thin keyline borders — developer security tooling with the visual temperature of a server room at night.

## Colors

| Role | Value |
|------|-------|
| bg | `#040406` |
| surface | `#0C0C0F` |
| border | `#19191D` |
| text | `#9194A1` |
| text_muted | `#5B5D66` |
| primary | `#9194A1` |
| accent | `#ABAEBB` |
| link | `#ABAEBB` |
| secondary | `#3C83F6` |
| button_bg | `#FFFFFF` |
| button_text | `#040406` |

**Using these colors**

- **Action color** `#FFFFFF` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `link` are all `#ABAEBB` — one role, not several.
- **accent** `#ABAEBB` — accent for emphasis — keep it rare on the page.
- **primary** `#9194A1` — ≈ the text color — a foreground/text color, not an action color (action = #FFFFFF).
- **secondary** `#3C83F6` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#0B0C0E` 62.9% · `#313234` 20.5% · `#1D1D20` 11% · `#7E7F84` 5.7%

## Typography

- Heading: **Inter**
- Body: **Inter**
- Mono: **JetBrains Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 64px / 400 · lh 72px |
| h2 | 52px / 400 · lh 59px |
| h3 | 44px / 400 · lh 50px |
| body | 16px / 400 · lh 22px |
| small | 15px / 400 · lh 19px |
| eyebrow | 14px / 400 · tracking 0.42px |

- Weight ladder: 400 · 500 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Inter — free, on Google.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 7px, 8px, 10px, 12px, 16px, 20px, 24px, 26px, 32px — snap all gaps/padding to these
- section rhythm: 200px top/bottom padding per section (measured)

## Radius
- base: 0px
- button: 0px
- card: 6px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFFFFF` / `#040406` | none | 0px | 0px 24px 0px 24px | 500 14px / -0.35px | none |
| secondary | `#040406` / `#FFFFFF` | 1px solid rgb(255, 255, 255) | 0px | 0px 24px 0px 24px | 500 14px / -0.35px | none |

**States (measured, not guessed)**

- primary hover: background `#E3E4E9`
- secondary hover: background `#1C1D22`
- transition: `color 0.2s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.12) 0px 8px 24px 0px`

## Motion
- durations: 200ms (dominant) · 80ms · 150ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `cubic-bezier(0, 0, 0.2, 1)`
- animated properties: opacity, color, background-color, border-color

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

## Their own tokens (verbatim from :root)

## Layout (measured)
- container max 1616px · common grid: 2-col
- nav: 54px sticky

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 0 | 1019 | — | — | 0/0 | — |

## Motion choreography (measured)
Load order: `div.c15t-ui-root-hE9Kz` @0ms → `div.c15t-ui-root-hE9Kz` @0ms → `div.rive-touch-scroll-fix`×4 @346ms

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)
- card ×4: pad 26px 32px 24px 32px · r 0px · border 1px solid rgb(46, 48, 56) · bg #040406
  - hover: font-weight `400` · letter-spacing `normal`

## Responsive (measured)
- breakpoints: 480px · 640px · 768px · 1024px · 1280px · 1536px
- mobile (390px): hero 36px · body 16px · nav: inline

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
