### What is the Remix design system?

The design system on this page is remix.run’s, as measured on November 4, 2026: Inter type, #FE4754 as the main color and pill-shaped corners, written down as a DESIGN.md. It is not Remix’s own documentation.

### What is Remix built with?

Remix’s website (remix.run) is built with Remix, Fly.io, Fastly and Three.js. The full tech stack Sitepeel found: Three.js, Fly.io, Fathom, Remix and Fastly. Measured on November 4, 2026.

### What is the Remix DESIGN.md?

A plain-text file with Remix’s measured colors, type, spacing, corners and components as tokens, plus short rules, in the DESIGN.md format Google published with Stitch. Your AI coding agent reads it and builds in this style. More about DESIGN.md.

### How do I use it with Claude Code or Cursor?

Download the file and put it in your project’s root folder, then ask your agent to follow DESIGN.md. Step-by-step guides: Claude Code, Cursor, Codex, GitHub Copilot.

### Is this Remix’s official design system?

No. Sitepeel measured it from remix.run’s public page on November 4, 2026. It is an independent analysis, not made or approved by Remix.

### Can I use Remix’s style in my own product?

Use it to learn, prototype and compare. For a real product, make the style your own, and never copy Remix’s logo, name, pictures or text.

### How accurate are the values?

Each value was measured on the rendered page after it fully loaded, on desktop and mobile: colors where they appear, type with tracking, spacing, corners, shadows and hover states. Sites change, so check the date at the top.

# Remix Design System

## Overview

Remix describes itself as: “The fully-stacked web framework” The interface is dark, built on **Near Black (#000000)** with **Cool Mist (#DEE2E6)** text, and **Red (#FE4754)** as the main accent.

Type is set in **Inter**, with **JetBrains Mono** for code. Headlines run large with tight negative tracking; body text is 16px. The surface language is flat. Controls are pill-shaped.

Measured from [remix.run](https://remix.run/) on November 4, 2026 at 1440×900 and 390×844 from 141 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 14 roles.

- **Near Black (#000000):** Page background, seen 2 times. Token `background`.
- **Cool Mist (#DEE2E6):** Primary text and headings, seen 23 times. Token `on-surface`.
- **White (#FFFFFF):** Headings and emphasis, seen 23 times. Token `on-surface-strong`.
- **Silver (#C2C2C2):** Secondary text, seen 8 times. Token `on-surface-variant`.
- **Silver (#B8B8B8):** Muted text and metadata, seen 7 times. Token `on-surface-muted`.
- **Cool Charcoal (#1E2226):** Raised areas one step from the page, seen 6 times. Token `surface-container-low`.
- **White 2% (#FFFFFF06):** Translucent fill for cards and controls, seen 6 times. Token `overlay`.
- **White 20% (#FFFFFF33):** Stronger translucent fill, seen 3 times. Token `overlay-strong`.
- **Indigo 11% (#7A74A11D):** Borders and dividers, seen 12 times. Token `outline`.
- **White 10% (#FFFFFF1A):** Secondary dividers, seen 6 times. Token `outline-variant`.
- **Red (#FE4754):** Primary buttons and calls to action, seen 6 times. Token `primary`, CSS `--brand-cycle`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Vivid Blue (#2DACF9):** Accent on large areas, seen 6 times. Token `secondary`.
- **Green (#7CE95A):** Accent on large areas, seen 2 times. Token `tertiary`.

## Typography

**Inter** and **JetBrains Mono** (monospace) share the interface. Fallback stack: `Inter, Inter Fallback, ui-sans-serif, system-ui`.

- **headline-display:** Inter 84px at weight 700, line height 1, tracking -0.03em (42px on mobile). Page title (h1).
- **headline-lg:** Inter 50px at weight 700, line height 1.04, tracking -0.02em (32px on mobile). Section headings (h2).
- **body-md:** Inter 16px at weight 400, line height 1.5. Body text.
- **body-lg:** Inter 18px at weight 700, line height 1.3, tracking -0.015em. Lead paragraphs.
- **label-md:** Inter 13px at weight 500, line height 1. Buttons, navigation and labels.
- **code:** JetBrains Mono 16px at weight 400, line height 1.5. Code and technical values.

## Layout

Spacing does not follow a strict grid: 69% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 4px, sm 6px, md 14px, lg 32px, xl 48px.
- **Sections:** 160px vertical padding between major sections.
- **Gaps:** 8px is the most common gap in flex and grid layouts.
- **Page margin:** 36px on each side of full-width sections.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from tonal surface steps (#1E2226) and #7A74A11D borders.

## Shapes

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

- **full (9999px):** 52 elements.
- **md (13px):** 4 elements.

## Components

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

- **button-primary (“SERVER”):** #FE4754 fill, #FFFFFF text, 12px/500, padding 0px 18px.
- **button-primary-hover:** background #9B7191, text #FFFFFF on hover.
- **button-secondary (“[D] DOCS”):** #1E2226 fill, #DEE2E6 text, 12px/400, padding 4px 6px.
- **button-secondary-hover:** background #1E2226, text #ED4643 on hover.
- **button-outline (“Request”):** #FE6F7E27 fill, #FFFFFF text, 13px/500, 999px radius, padding 0px 14px 1px 14px, border 1px solid #FE4A5C85.
- **button-ghost (“npm”):** #FFFFFF09 fill, #FFFFFF text, 13px/500, 13px 0px 0px 13px radius, padding 0px 12px.
- **input-field (“name@example.com”):** transparent fill, #FFFFFF text, 16px/400, 999px radius, padding 0px 18px, border 1px solid #FFFFFF2E.
- **link:** transparent fill, #DEE2E6 text, padding 0px.

## Do's and Don'ts

- Do use #000000 for the page and lift surfaces in small steps: #1E2226.
- Do keep text in 4 levels: #DEE2E6, #FFFFFF, #C2C2C2, #B8B8B8.
- Do reserve #FE4754 for primary actions and key highlights.
- Do set headlines in Inter with tight tracking (-0.03em).
- Do reuse the measured spacing steps (6px, 14px, 32px).
- Do make buttons and chips fully rounded (9999px); most other elements use 13px corners.
- Don't add drop shadows for depth; use tonal surfaces.
- Don't introduce new font families beyond Inter and JetBrains Mono.
- Don't use #FE4754 for large backgrounds or body text.
- Don't make interface transitions slower than 0.16s.

## Motion

Interface transitions are quick: 0.16s, 0.15s. Longer ambient animations run 10s.

- **Easing:** `ease`, `linear`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
