## What it is
Fontsource is a monorepo of open-source fonts packaged into individual NPM packages for self-hosting in web applications. It bundles over 2,000 font families with CSS files, enabling version-locked, offline-capable font loading without third-party CDNs.

## Use cases
- self-host google fonts instead of using the CDN
- improve website performance by removing external font requests
- version lock fonts as npm dependencies
- load fonts offline in progressive web apps
- avoid google tracking font usage for privacy
- use open source fonts not available on google fonts
- bundle fonts into a javascript build pipeline

## When to choose
- you want fonts managed like any other npm dependency with version locking
- you need offline font support for PWAs
- you care about privacy and want to avoid Google Fonts CDN tracking
- you want to reduce DNS/TCP latency from external font requests
- you need fonts outside the Google Fonts ecosystem

## When to avoid
- you are fine with Google Fonts CDN and don't need self-hosting
- you need commercial/licensed fonts not in the open-source collection
- you want a font CDN service rather than npm packages
