Sentry — design system & UI screens

Dev Tools · 2 screens · 16 sections · sentry.io

Full-bleed dark purple cosmic landing page whose signature is a glossy 3D purple astronaut clutching a wrench, floating among scattered floating error/replay/trace UI panels and a glowing "Root Cause" callout. The headline "Code breaks, fix it faster" mixes white and pink-script weights, and the body alternates large pink-accented section titles ("Developer first. Always.", "Everything's connected") with dark rounded cards showing terminal install snippets, Seer AI root-cause readouts, and inline product screenshots. Distinctive flat cartoon developer illustrations, a trust logo row (GitHub, Disney, Atlassian, Linear, Vercel), compliance badges, and a violet newsletter block punctuate the long scroll.

Decoded design system

Sentry's decoded design system: background #1F1633, text #ECECEE, accent #6A5FC1, link #6A5FC1, primary #6A5FC1; type scale h1 88px / h2 60px / body 16px; 4px spacing base; 8px base radius. The single interactive/action color is #6A5FC1 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

text	`#ECECEE`
text_muted	`#9E9AA6`
primary	`#6A5FC1`
accent	`#6A5FC1`
link	`#6A5FC1`
secondary	`#FF45A8`
button_bg	`#6A5FC1`
button_text	`#FFFFFF`

Using these colors

Action color #6A5FC1 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #6A5FC1 — one role, not several (the action color).
accent #6A5FC1 — 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.
secondary #FF45A8 — 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.
