@posthog/brand

Every PostHog brand asset in one npm package: the logo, the colors, the font (RoundHog), 160+ hedgehogs, and the team crests — as React components, raw SVGs, PNG URLs, color tokens, and woff2 files. All bundled, so nothing is fetched at runtime.

pnpm add @posthog/brand

🦔 brand.posthog.com has every asset with the import line for each one. Browse there, come back here for the API.

⚠️ Pre-1.0. While we're on 0.x, exports can be renamed or removed in a minor bump. Pin an exact version if that would ruin your week; we'll follow semver strictly from 1.0.0.

Five subpaths, five kinds of asset

import { Logo } from "@posthog/brand/logo"
import { colors } from "@posthog/brand/colors"
import { roundHogFontFaceCss } from "@posthog/brand/fonts/css"
import { HedgehogDoctorHog } from "@posthog/brand/hoggies"
import { MarketingCrest } from "@posthog/brand/crests"

Import from the subpath you need; nothing else tags along. Every illustration takes two friendly props — size (the width; height follows the artwork's aspect ratio, so nothing stretches) and title (an accessible label; without one the image is decorative) — plus any other <svg> prop, and carries its own metadata as a static .meta. Hover a component in your editor and the TSDoc tells you the rest.

Logo

import { Logo } from "@posthog/brand/logo"

<Logo />                                  // landscape, full gradient (the defaults)
<Logo variant="mono" color="#fff" />      // one color, e.g. on a dark background
<Logo variant="print" layout="stacked" /> // 4-color/CMYK, portrait
<Logo.Logomark />                         // just the hog
<Logo.Wordmark />                         // just the word

Prop	Values	Default
variant	"gradient" · "print" (4-color/CMYK) · "mono"	"gradient"
layout	"landscape" · "stacked" · "logomark" · "wordmark"	"landscape"
color	any CSS color — mono only	currentColor

A mono logo (and the always-mono wordmark) draws with currentColor, so it picks up the surrounding text color unless you say otherwise.

Colors

A plain object. No React, no markup, no surprises.

import { colors } from "@posthog/brand/colors"

colors.blue.core // "#1490E8"
colors.blue.lighter // a lighter tint
colors.blue.darker // a darker shade
colors["corn-blue"].gradient // ["#2BB3DF", "#1A89AD"] — [from, to]

Writing CSS instead? import { colorsCss } from "@posthog/brand/colors/css" gives you a ready-made block of custom properties (--posthog-blue, --posthog-blue-lighter, --posthog-blue-gradient, …) to drop in a <style> tag.

Fonts

RoundHog, bundled as eight woff2 faces (Regular / Medium / SemiBold / Bold, upright and italic). Weights map to PostHog's type scale: 400 / 500 / 700 / 800.

import { roundHogFontFaceCss } from "@posthog/brand/fonts/css"

document.head.insertAdjacentHTML("beforeend", `<style>${roundHogFontFaceCss}</style>`)
// now anywhere: font-family: "RoundHog", sans-serif

Registering the faces yourself?

For a custom @font-face, a <link rel="preload">, or a Next.js localFont, take the metadata or a single URL instead of the CSS string:

import { roundHog, roundHogRegularUrl } from "@posthog/brand/fonts"

roundHog.family // "RoundHog"
roundHog.faces // [{ weight, style, url, format }, …] — the eight bundled faces
roundHogRegularUrl // the bundled woff2 URL for 400 upright

The files are also reachable by subpath — @posthog/brand/fonts/RoundHog.woff2 — so a build step can require.resolve one to copy into a static dir.

Hoggies

The hedgehogs. Each is a component named Hedgehog<Name>:

import { HedgehogDoctorHog, HedgehogWizard } from "@posthog/brand/hoggies"

<HedgehogDoctorHog size={120} title="A hedgehog doctor" />
<HedgehogWizard variant="5" size={120} /> // wizards come in five flavors

Where a hog has numbered siblings in Figma they ship as one component with a variant prop (keys are strings; the lowest is the default) rather than five near-identical exports.

Crests

Team crests, each one component in two tiers: the base is the full illustration, .Mini is a simplified badge that survives being 24px tall.

import { MarketingCrest } from "@posthog/brand/crests"

<MarketingCrest size={64} />      // the full crest
<MarketingCrest.Mini size={24} /> // the badge

A few crests only exist in one size; for those .Mini renders the same artwork. To pull a single tier, use @posthog/brand/crests/full (MarketingCrest) or @posthog/brand/crests/mini (MarketingCrestMini).

Raw SVGs and PNGs

Not everything is React. Every asset also ships as an SVG string (to inline into an email or a non-React app) and a bundled PNG URL (for an <img>):

import hedgehogChartSvg from "@posthog/brand/hoggies/svg/chart" // an SVG string
import hedgehogChartPng from "@posthog/brand/hoggies/png/chart" // a bundled PNG URL

All /svg and /png subpaths

Every illustration group has the same shape. Replace <g> with hoggies, crests/full, or crests/mini (the combined crests barrel and the logo are React-only):

Subpath	Returns
@posthog/brand/<g>	React components
@posthog/brand/<g>/svg	barrel of named SVG strings (hedgehogDoctorSvg)
@posthog/brand/<g>/svg/<slug>	a single SVG string as the default export
@posthog/brand/<g>/png	barrel of named PNG URLs (hedgehogDoctorPng)
@posthog/brand/<g>/png/<slug>	a single PNG URL as the default export
@posthog/brand/<g>/metadata	the group's AssetMeta[] manifest (React-free)

// One asset, one module:
import marketingCrestPng from "@posthog/brand/crests/full/png/marketing"

// Or several from one barrel:
import { hedgehogChartSvg, hedgehogCroissantSvg } from "@posthog/brand/hoggies/svg"

// Or lazily, by slug, without bundling the namespace:
const svg = (await import("@posthog/brand/hoggies/svg/" + slug)).default

Named exports are lowerFirst(ComponentName) + "Svg" / + "Png"; crest minis keep the trailing Mini (marketingCrestMiniPng). SVGs are minified with SVGO and PNGs quantized with pngquant plus oxipng before they're committed, so everything stays small.

Metadata and search

The root export is React-free and image-free — types, the cross-namespace manifest, and enough helpers to build an asset picker without pulling in a single illustration:

import { allAssets, findAssets, getAsset, getComponentName } from "@posthog/brand"

findAssets({ namespace: "hoggies", text: "director" })
findAssets({ namespace: "crests", tier: "mini", text: "marketing" })
getAsset("crests", "marketing", "mini") // full AssetMeta; tier disambiguates the slug
getComponentName("hoggies", "director") // "HedgehogDirector"

Per-namespace manifests live at @posthog/brand/<g>/metadata if you don't want the whole set.

How assets get here

The assets live in PostHog's brand-book Figma file. A daily GitHub Action renders every component to SVG + PNG through the Figma API, commits what changed (plus a changeset) straight to main, and that triggers a release: version bump, then npm publish via trusted publishing (OIDC), gated on Slack approval per the SDK release process.

Two things are hand-maintained rather than synced, because they're small and rarely change: the palette (static/colors.ts) and the logo geometry (src/logo/).

Demo site

brand.posthog.com is built from site/ — a Vite + React app that imports @posthog/brand as a workspace dependency, so it renders the real built components and doubles as an integration test of the published exports. It deploys to Cloudflare Pages.

pnpm dev:site       # build the package, then run the site locally
pnpm build:site     # build the package, then the static site into site/dist
pnpm gen:site-icons # re-render the favicons and the social card up there ☝️

The icons and that big image at the top of this README are generated from the package itself — the <Logo> geometry, the palette, and a few hedgehogs. The build also writes one static HTML file per page (and per crest), with real metadata and content, plus sitemap.xml and llms.txt, so crawlers and answer engines that never run JavaScript still get the goods. See site/seo-plugin.ts.
