# Better Stack Design System

## Overview

Better Stack describes itself as: “AI SRE and MCP server, incident management, on-call, logs, metrics, traces, and error tracking. 7,000+ happy customers. 60-day money back guarantee.” The interface is dark, built on **Cool Charcoal (#0B0C14)** with **Blue (#939DB8)** text, and **Indigo (#5B63D3)** as the main accent.

Type is set in **Helvetica Now Display** and **Helvetica Now Text**. Headlines run large; body text is 14px. Depth comes from hairline borders and inset highlights rather than drop shadows. Controls are pill-shaped.

Measured from [betterstack.com](https://betterstack.com/) on November 4, 2026 at 1440×900 and 390×844 from 323 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 16 roles, plus gradient stops #939DB8, #5B63D3, #7C87F7.

## Typography

**Helvetica Now Display** and **Helvetica Now Text** share the interface. Fallback stack: `Helvetica Now Display, Helvetica Now Display Extended, ui-sans-serif, system-ui`.

- **headline-display:** Helvetica Now Display 53px at weight 500, line height 1.1 (40px on mobile). Page title (h1).
- **headline-lg:** Helvetica Now Display 40px at weight 700, line height 0.6 (28px on mobile). Section headings (h2).
- **headline-md:** Helvetica Now Text 28px at weight 700, line height 1.17. Sub-section headings.
- **body-md:** Helvetica Now Text 14px at weight 400, line height 1.55. Body text.
- **body-sm:** Helvetica Now Text 13px at weight 400, line height 1.6. Secondary and small text.
- **caption:** Helvetica Now Text 12px at weight 400, line height 1.5. Captions and fine print.
- **label-md:** Helvetica Now Text 16px at weight 400, line height 1.5. Buttons, navigation and labels.

## Layout

Spacing is mostly on a 4px grid (89% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** xs 4px, sm 8px, md 12px, lg 20px, xl 60px.
- **Container:** content is capped at 1100px.

## Elevation & Depth

The design avoids drop shadows. Layers are separated by tonal surface steps (#0F101A → #171926) and hairline rings:

- `rgba(255, 255, 255, 0.25) 0px 1px 3px 0px inset`

## Shapes

Interactive controls are pill-shaped. Measured radii, most used first:

- **md (16px):** 148 elements.
- **full (9999px):** 104 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“Sign up”):** transparent fill, #FFFFFF text, 13px/500, 8px radius, padding 0px 8px, border 1px solid #FFFFFF1C, shadow `rgba(255, 255, 255, 0.25) 0px 1px 3px 0px inset`.
- **button-outline (“Explore pricing”):** #171926 fill, #C9D3EE text, 13px/400, 43px radius, padding 0px 12px, border 1px solid #939DB833.
- **button-ghost (“Platform”):** transparent fill, #C9D3EE text, 13px/400, padding 12px 24px 12px 12px.
- **input-field (“Your work e-mail”):** transparent fill, #FFFFFF text, 16px/400, 12px radius, padding 0px 20px.
- **link:** transparent fill, #98A4F7 text, padding 0px.

## Do's and Don'ts

- Do use #0B0C14 for the page and lift surfaces in small steps: #0F101A, #171926.
- Do keep text in 4 levels: #939DB8, #FFFFFF, #C9D3EE, #646E87.
- Do use #5B63D3 as the brand accent: header, logo and key highlights.
- Do reuse the measured spacing steps (8px, 12px, 20px).
- Do make buttons and chips fully rounded (9999px); most other elements use 16px corners.
- Don't use #646E87 for body text; it reaches 3.83:1 on #0B0C14. Keep it for large text or metadata.
- Don't add drop shadows for depth; use hairline rings and tonal surfaces.
- Don't introduce new font families beyond Helvetica Now Display and Helvetica Now Text.
- Don't use #5B63D3 for large backgrounds or body text.
- Don't make interface transitions slower than 0.4s.

## Motion

Interface transitions are quick: 0.15s, 0.4s. Longer ambient animations run 1s.

- **Easing:** `cubic-bezier(0.4, 0, 0.2, 1)`, `ease`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
