# E2B

> Extracted from [https://e2b.dev/](https://e2b.dev/) 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

E2B uses a dark canvas (#000000) with a palette led by #E32A01. Type is set in **PP Supply Sans** (display), **Inter**, **Commit Mono** (mono), with 16px body text. Layout: 1280px container, top-fixed navigation, 15 sections. Built with next.js, tailwind, radix-ui, lenis, google-tag-manager, 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 |
|---|---|---|---|---|---|
| `background` | `#000000` | 0 0 0 | bg | 77.4% | `--color-bg` |
| `on-surface-variant` | `#A6A6A6` | 0.725 0 173.9 | muted | 2.4% | `--color-fg-hover` |
| `outline` | `#2C2C2C` | 0.293 0 129.6 | border | 1.9% | `--color-line` |
| `on-surface` | `#FFFFFF` | 1 0 0 | text | 1.6% | `--white` |
| `primary` | `#E32A01` | 0.59 0.222 32.2 | accent | 0.32% | `--color-accent-mark` |
| `neutral-4` | `#1F1F1F` | 0.239 0 240.2 | other | 6.3% | `--neutral-4` |
| `neutral-12` | `#F4F4F4` | 0.967 0 129.6 | other | 5.4% | `--neutral-12` |
| `neutral-3` | `#141414` | 0.191 0 129.6 | other | 3.1% | `--neutral-3` |
| `neutral-11` | `#E6E6E6` | 0.925 0 172.5 | other | 0.37% | `--neutral-11` |
| `neutral-8` | `#8A8A8A` | 0.633 0 129.6 | other | 0.32% | `--neutral-8` |
| `neutral-6` | `#3D3D3D` | 0.36 0 173.9 | other | 0.28% | `--neutral-6` |

Declared brand/accent tokens: `--color-accent-wash` = `#260101`.

Contrast: text on background 21:1, muted text 8.63:1, accent 4.6:1.

Gradients in use: `radial-gradient(closest-side, color(srgb 0.721569 0.721569 0.721569 / 0.85), color(srgb 0.721569 0.721569 0.721569 / 0.3))`; `linear-gradient(135deg, lab(4.10949 17.0684 6.11146), lab(0 0 0) 58%)`.

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

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **PP Supply Sans** | display | 300, 580, 600 | 54.6% | webfont |
| **Inter** | body | 400, 520, 580 | 35.2% | webfont |
| **Commit Mono** | mono | 400 | 10.3% | webfont |

Scale (px): 11, 12, 14, 15, 16, 18, 24, 56, 72, 180. Effective ratio ≈ 1.623 (close to a golden ratio). Body 16px at line-height 1.5; display 180px with tracking -0.02em. Headings are sentence case. On a 390px viewport the body is 16px and display 72px.

## Layout

Spacing has no reliable single base unit; the most used steps are 2, 2.5, 3.5, 4, 6, 8, 8.5, 10, 11, 12, 16, 18, 20, 24px. Sections open with about 116px of space before their first line of text. Content sits in a 1280px container on a 12-column grid. Text density 0.103 (text area / page area).

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

1. **nav** (64px, bg #000000)
2. **hero** (900px, bg #000000)
3. **logos** (258px, bg #000000)
4. **section** — “runs. it where is E2B product. the is agent Your” (4160px, bg #000000)
5. **testimonials** — “agent. any train and Build” (1569px, bg #000000)
6. **section** — “needs agent your Everything” (1688px, bg #000000)
7. **section** — “standard. One API. Same yours. or cloud Our” (897px, bg #000000)
8. **section** — “speed. Container isolation. Full” (1450px, bg #000000)
9. **logos** — “words their In” (836px, bg #1F1F1F)
10. **section** — “Works with any agent stack.” (1864px, bg #000000)
11. **section** — “core the at Open” (771px, bg #000000)
12. **section** — “second. the by Billed start. to Free” (1317px, bg #000000)
13. **section** — “machine a agent every Give” (640px, bg #000000)
14. **footer** — “Resources” (594px, bg #000000)
15. **section** — “the VM apocalypse Help Vasek defeat” (720px, bg #F0EDE8)

## Elevation & Depth

Style: flat. Most used shadows:

- `rgba(227, 42, 1, 0.5) 0px 4px 8px 0px`

## Shapes

Dominant corner radius 0px; radii in use: 2px, 4px, 6px, 8px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#E32A01`, textColor `#FFFFFF`, rounded `0px`, padding `0px 18px`, height `44px`, fontFamily `Commit Mono`, fontSize `16px`, fontWeight `400`
- **button-secondary**: backgroundColor `#FFFFFF`, textColor `#000000`, rounded `0px`, padding `0px 16px`, height `36px`, fontFamily `Commit Mono`, fontSize `14px`, fontWeight `400`
- **card**: rounded `8px`, padding `24px`, border `1px solid #2C2C2C`

## Do's and Don'ts

- Do reserve `#E32A01` for primary actions and highlights; it covers only 0.32% of the painted page.
- Do set body copy in Inter at 16px / 1.5.
- Do use PP Supply Sans only for display sizes, not for body text.
- Do tighten large headlines (-0.02em at 180px).
- Don't introduce font weights beyond 300, 400, 520, 580, 600.
- Don't add drop shadows; depth comes from tone and borders.
- Do keep corners at 0px for most controls, and use the larger radii only for cards and media.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
