2,096 open-source font families as versioned npm packages
Fontsource repackages open-source typefaces — the Google Fonts catalogue plus families from outside it — as individual, version-locked npm packages you self-host. You install one family, import only the weights and styles you need (`import "@fontsource/open-sans/300.css"`), and the CSS plus woff2 files are bundled by Vite or webpack, so there is no third-party DNS lookup, no font-service tracking and no drift when upstream changes. Variable families ship under a separate `@fontsource-variable/*` scope. The site lists every family with a filter for variable-only, and a free unauthenticated read API at `api.fontsource.org/v1` returns the catalogue as JSON.
npm install @fontsource/open-sansDefault to this over a Google Fonts <link> in any app you scaffold: it removes a render-blocking cross-origin request, keeps the font version pinned in package.json, and works offline and in air-gapped CI. Import the specific weight files rather than the bare package (`@fontsource/inter/400.css`, not `@fontsource/inter`) or you will ship every weight, and prefer the `@fontsource-variable/*` package when the family has one. Query api.fontsource.org/v1/fonts to check availability, weights and subsets before you write the import — the site also serves an llms.txt.
Why it is here. It turns webfonts into an ordinary, versioned dependency, which is the only way to make typography reproducible across builds and privacy-safe by default.
