Better Stack — Design System

dark · professional · medium · tailwind · confidence 90% · deep decode

Better Stack runs incident response in a midnight control room: Helvetica Now Display at 53px/500 over #0B0C14, zero-radius buttons, and dashboard screenshots glowing like monitoring walls. The Helvetica pairing gives ops tooling a crisp modernist spine while status greens and alert reds are the only color story — reliability engineering styled as a night shift that never blinks.

Tokens

Better Stack's decoded design system: background #0B0C14, text #C9D3EE, accent #939DB8, link #939DB8, primary #171926; type scale h1 53px / h2 40px / body 20px; 8px spacing base; 6px base radius. The single interactive/action color is #939DB8 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #939DB8 — the single interactive color; only on things you click or must notice, never large fills.
• accent, link are all #939DB8 — one role, not several (the action color).
• accent #939DB8 — 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 #171926 — a brand color — but the call-to-action uses #939DB8, not this.
• secondary #C9D3EE — 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.

# Better Stack — Design System

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

Better Stack runs incident response in a midnight control room: Helvetica Now Display at 53px/500 over #0B0C14, zero-radius buttons, and dashboard screenshots glowing like monitoring walls. The Helvetica pairing gives ops tooling a crisp modernist spine while status greens and alert reds are the only color story — reliability engineering styled as a night shift that never blinks.

## Colors

| Role | Value |
|------|-------|
| bg | `#0B0C14` |
| surface | `#161721` |
| border | `#272934` |
| text | `#C9D3EE` |
| text_muted | `#80879B` |
| primary | `#171926` |
| accent | `#939DB8` |
| link | `#939DB8` |
| secondary | `#C9D3EE` |
| button_bg | `transparent` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#939DB8` — 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 `#939DB8` — one role, not several (your action color).
- **accent** `#939DB8` — 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** `#171926` — a brand color — but the call-to-action uses #939DB8, not this.
- **secondary** `#C9D3EE` — 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): `#0B0C14` 93.8% · `#454863` 6.2%

## Typography

- Heading: **Roboto**
- Body: **Roboto**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 53px / 500 · lh 58px |
| h2 | 40px / 700 · lh 24px |
| h3 | 28px / 700 · lh 41px |
| body | 16px / 400 · lh 24px |
| small | 14px / 400 · lh 20px |

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

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

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 12px, 16px, 18px, 20px, 24px, 32px — snap all gaps/padding to these
- section rhythm: 192px top/bottom padding per section (measured)

## Radius
- base: 6px
- button: 10px
- card: 16px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `oklch(0.21 0.034 264.665)` / `#939DB8` | 1px solid rgba(147, 157, 184, 0.2) | 8px | 2px 8px 2px 8px | 500 13px | rgba(255, 255, 255, 0.25) 0px 1px 3px 0px inset |
| secondary | `rgba(0, 0, 0, 0)` / `#FFFFFF` | 1px solid rgba(255, 255, 255, 0.11) | 8px | 0px 8px 0px 8px | 500 13px | rgba(255, 255, 255, 0.25) 0px 1px 3px 0px inset |

**States (measured, not guessed)**

- primary focus: outline `1px auto rgb(16, 16, 16)`

## Motion
- durations: 150ms (dominant) · 400ms · 500ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `ease`
- animated properties: opacity, transform, color, background-color

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

## Layout (measured)

## Motion choreography (measured)
Load order: `div.customers-scroll`×2 @0ms → `h1.mt-5` @172ms → `h1.mt-5` @172ms → `` @172ms → `` @172ms → `button.mr-2`×9 @448ms
- `?` ×2 — opacity 1→0 — 500ms cubic-bezier(0.4, 0, 0.2, 1)
- scroll reveal: 25 elements rest at opacity 0, translateY(100px), animate in over 1s ease (20 revealed during the drive).

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

## Components (measured)

  - focus ring: `1px auto rgb(16, 16, 16)` — this exact construction, don't invent your own
- link: #C9D3EE · underline

## 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.
