# Sentry

> Extracted from [https://sentry.io/welcome/](https://sentry.io/welcome/) on 2026-11-12 by Emblematic. Every value below was read from the rendered DOM (computed styles, `document.fonts`, and the fonts Chrome actually used to paint text), not estimated from pixels. When the YAML front matter and this prose disagree, the YAML wins. Copy values from this file exactly; don't transcribe them from memory. Don't copy logos, imagery, illustrations or marketing copy.

## Overview

Sentry uses a dark canvas (#150F23) with a palette. Type is set in **Monaco** (mono), **Rubik**, **Dammit Sans** (display), with 16px body text. Layout: 1152px container, none-detected navigation, 8 sections. Built with astro, tailwind, vercel.

## Colors

Area-weighted from painted backgrounds, text and borders on the 1440px light capture. Roles are inferred from usage (largest background, most text, interactive fills). Every hex is an exact computed value; a role marked *unverified* is a best guess that has not passed review, so its canonical token (e.g. `primary`) is left out of the front matter.

| Token | Hex | OKLCH | Role | Share of paint | CSS variable |

Sparse chromatic highlights (not accents): `#79628C` (`--color-lt-violet`).

Contrast: text on background 18.68:1, muted text 3.88:1, accent 7.72:1.

Gradients in use: `linear-gradient(rgb(31, 22, 51) 0%, rgb(48, 20, 95) 52.4%, rgb(48, 20, 95) 75%, rgb(48, 20, 95) 100%), url("https://sentry.io/_astro/middle-`; `radial-gradient(50% 50%, rgba(173, 108, 170, 0.15) 0%, rgb(31, 22, 51) 65%)`.

The site does not change under `prefers-color-scheme: dark`.

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Monaco** | mono | 400 | 52.2% | system (stack `Monaco, Menlo, "Ubuntu Mono", monospace`, resolved on macos) |
| **Rubik** | body | 400, 500, 700 | 28.4% | webfont |
| **Dammit Sans** | display | 500, 700 | 17.5% | webfont |
| **Menlo** | other | 400 | 1.3% | system (stack `"IBM Plex Mono", Consolas, "Liberation Mono", Menlo, Courier`, resolved on macos) |

Scale (px): 12, 14, 15, 16, 20, 24, 27, 30, 60, 88. Effective ratio ≈ 1.329 (close to a perfect fourth). Body 16px at line-height 1.5; display 88px with tracking 0em. Headings are sentence case. On a 390px viewport the body is 16px and display 50.19px.

## Layout

Spacing follows a 4px base unit; the most used steps are 2, 4, 6, 8, 12, 16, 20.5, 24, 32, 64, 144px. Sections open with about 25px of space before their first line of text. Content sits in a 1152px container on a 2-column grid. Text density 0.281 (text area / page area).

Section order (desktop). Kinds below the review threshold are shown as *section*:

1. **hero** (1807px, bg #1F1633)
2. **section** — “Developer first.” (2935px, bg #1F1633)
3. **section** — “Loved by developers” (528px, bg #1F1633)
4. **section** — “Get started” (962px, bg #1F1633)
5. **section** — “Built to be secure,” (603px, bg #1F1633)
6. **newsletter** — “Get monthly product updates” (461px, bg #1F1633)
7. **section** — “Fix It” (698px, bg #1F1633)
8. **footer** — “Get Help” (727px, bg #1F1633)

## Elevation & Depth

Style: subtle. Most used shadows:

- `rgba(0, 0, 0, 0.15) 0px 2px 10px 0px inset`
- `rgba(0, 0, 0, 0.08) 0px 2px 8px 0px`
- `rgba(0, 0, 0, 0.1) 0px 1px 3px 0px inset`

## Shapes

Dominant corner radius 0px; radii in use: 8px, 10px, 10.5px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#FA7FAA`, textColor `#1F1633`, rounded `8px`, padding `12px 16px`, height `40px`, fontFamily `Rubik`, fontSize `14px`, fontWeight `700` (e.g. “Get Started”)
- **button-secondary**: backgroundColor `#C83852`, textColor `#FFFFFF`, rounded `8px`, padding `12px 16px`, height `40px`, fontFamily `Rubik`, fontSize `14px`, fontWeight `700` (e.g. “Get Demo”)
- **card**: rounded `10.6px`, padding `0px`, backgroundColor `#1F1633`
- **input**: rounded `6px`, height `42px`, padding `8px 12px`, backgroundColor `#FFFFFF`, border `1px solid #CFCFDB`

## Do's and Don'ts

- Do set body copy in Rubik at 16px / 1.5.
- Do use Dammit Sans only for display sizes, not for body text.
- Don't introduce font weights beyond 400, 500, 700.
- Do keep corners at 0px for most controls, and use the larger radii only for cards and media.
- Do snap spacing to multiples of 4px.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
