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

Upstash headlines 'Serverless Data Platform' in Inter Tight at a colossal 128px/700 with gradient fills, Inter at 16-20px underneath, and emerald 12px-radius CTAs. Redis/Vector/QStash product tabs with live code panels do the substance — data infrastructure that spends its entire display budget on one enormous, confident line.

Tokens

Upstash's decoded design system: background #F5F5F5, text #000000, accent #00BC7D, link #00BC7D, primary #022C22; type scale h1 128px / h2 24px / body 16px; 8px spacing base; 12px base radius. The single interactive/action color is #00BC7D — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Upstash — Design System

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

Upstash headlines 'Serverless Data Platform' in Inter Tight at a colossal 128px/700 with gradient fills, Inter at 16-20px underneath, and emerald 12px-radius CTAs. Redis/Vector/QStash product tabs with live code panels do the substance — data infrastructure that spends its entire display budget on one enormous, confident line.

## Colors

| Role | Value |
|------|-------|
| bg | `#F5F5F5` |
| surface | `#E6E6E6` |
| border | `#D0D0D0` |
| text | `#000000` |
| text_muted | `#5D5D5D` |
| primary | `#022C22` |
| accent | `#00BC7D` |
| link | `#00BC7D` |
| secondary | `#007A55` |
| button_bg | `#00BC7D` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#00BC7D` — 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`, `button_bg` are all `#00BC7D` — one role, not several (your action color).
- **accent** `#00BC7D` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **primary** `#022C22` — a brand color — but the call-to-action uses #00BC7D, not this.
- **secondary** `#007A55` — 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): `#FFFFFF` 54.1% · `#E0F0EA` 32.6% · `#619580` 13.3%

## Typography

- Heading: **Inter Tight** _(free fallback: Newsreader)_
- Body: **Inter**
- Mono: **__JetBrains_Mono_3c557b** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 180px / 700 · lh 225px |
| h2 | 128px / 700 · lh 128px · tracking -3.2px |
| h3 | 48px / 600 · lh 48px |
| body | 16px / 400 · lh 24px |
| small | 14px / 400 · lh 21px |

- Weight ladder: 400 · 500 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Inter Tight may be proprietary — safe free fallback: Newsreader (Google Fonts). Inter — free, on Google.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 12px, 16px, 20px, 24px, 32px, 40px — snap all gaps/padding to these
- section rhythm: 64px top/bottom padding per section (measured)

## Radius
- base: 12px
- button: 12px
- card: 35px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFFFFF` / `#DC2626` | 2px solid rgb(255, 255, 255) | 16px 16px 0px 0px | 0px 32px 0px 32px | 600 24px | none |
| secondary | `oklch(0.696 0.17 162.48)` / `#FFFFFF` | none | 12px | 8px 32px 8px 32px | 500 16px | none |

**States (measured, not guessed)**

- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: box-shadow `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.05) 0px 1px 2px 0px` · background `oklch(0.508 0.118 165.612)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.05) 0px 1px 2px 0px`
- card: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 1px 3px 0px, rgba(0, 0, 0, 0.1) 0px 1px 2px -1px`

## Motion
- durations: 150ms (dominant) · 300ms · 2000ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `cubic-bezier(0.4, 0, 0.6, 1)`
- animated properties: color, background-color, border-color, text-decoration-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)

| Token | Value |
|-------|-------|
| `--color-bg` | `oklch(0.97 0 0)` |
| `--color-bg-mute` | `rgba(4,120,87,.08)` |

| `--color-primary-text` | `oklch(0.508 0.118 165.612)` |

| `--font-display` | `"__Inter_Tight_a3c0d3","__Inter_Tight_Fallback_a3c0d3"` |

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- container max 1200px · common grid: 4-col
- nav: 125px fixed · bg oklch(0.97 0 0)

## Motion choreography (measured)
Load order: `h5.absolute` @0ms → `span.-ml-1`×2 @0ms
- `h5.absolute` — opacity 1→1 — 4000ms cubic-bezier(0.4, 0, 0.6, 1) · loops
- `span.-ml-1` ×2 — opacity 1→1 — 2000ms cubic-bezier(0.4, 0, 0.6, 1) · loops
- scroll reveal: 9 elements rest at opacity 0, animate in over 4000ms (0 revealed during the drive).
- overlay dialog (auto-opened): panel #FFFFFF · r 12px · shadow rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.25) 0px 25px 50px -12px

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

## Components (measured)
- card ×4: pad 32px 32px 32px 32px · r 35.2px 8px 8px 35.2px · bg #FFFFFF
  - hover: box-shadow `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 20px 25px -5px, rgba(0, 0, 0, 0.1) 0px 8px 10px -6px` · font-weight `400` · letter-spacing `normal`
- link: #FFFFFF · no underline

## Themes (both measured)
- dark counterpart: bg `#09090B` · text `#ECFDF5`
- tokens that flip between modes:
  - `--color-bg`: `oklch(0.97 0 0)` → `#09090b`
  - `--color-bg-mute`: `rgba(4,120,87,.08)` → `rgba(236,253,245,.06)`
  - `--color-primary-text`: `oklch(0.508 0.118 165.612)` → `oklch(0.765 0.177 163.223)`
  - `--color-text`: `#022c22` → `#ecfdf5`
  - `--color-text-mute`: `oklch(0.552 0.016 285.938)` → `oklch(0.705 0.015 286.067)`

## Responsive (measured)
- breakpoints: 420px · 640px · 768px · 1024px · 1280px
- mobile (390px): hero 48px · body 14px · nav: hamburger

## 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.
