Sentry design system

What font does Sentry use?

Sentry’s website uses Dammit Sans for headings and Monaco for body text. Dammit Sans is not on Google Fonts; the closest free match is Figtree; Monaco is a system font, already on Windows and macOS.

Sentry colour palette

Sentry’s home page is dark (#1F1633 background, #FFFFFF text) and uses #6A5FC1 for its main actions. Its palette: #1F1633, #150F23, #FFFFFF, #6A737D, #E1E4E8, #9ECBFF.

Type scale

Each size the page sets text in, with its weight and line height. Sentry’s largest type is 88px at weight 700.

Spacing and shape

Spacing sits on a 4px grid: 4px, 8px, 12px, 16px, 20px, 24px, 32px, 36px, 40px, 44px, 48px, 56px.

Corner radii: 6px, 8px, 10px, 10.6px, 12px, pill. 4 shadow levels measured.

What makes Sentry look like Sentry

Almost entirely neutral: 96% of the page is painted in #1F1633 and #150F23.

#9ECBFF is an accent: 0.9% of the page, used for text only. Don't fill large areas with it.

#422082 is an accent: 0.7% of the page, as small fills such as buttons and badges. Keep it to small areas.

The largest type (88px Dammit Sans) is bold (700).

Sentry DESIGN.md for Claude Code, Cursor and Lovable

A DESIGN.md is the brief an AI coding tool reads before it writes UI. This one carries everything on this page as rules a model follows: the allowed colours and what each is for, the fonts with free stand-ins, the type scale, spacing, corners, and the things Sentry’s design never does.

Put it in your project root and ask your tool to follow it: “Read DESIGN.md and build [your product] in this design language.” It describes a style, not Sentry’s product, so use your own name, words and images.

The measured values as CSS custom properties, with free fonts standing in for licensed ones. Use them to learn from or to start a project in a similar style; Sentry’s name, logo, words and images are theirs.

How this was measured

PikSpec’s scanner read the sentry.io home page in Chrome at 1440px wide on 15 October 2026: the computed styles of its elements, the fonts that rendered and how much of the page each colour covers. Websites change; capture the page yourself with PikSpec for today’s values, any page, and exports in five formats.
