Working with these fonts

Not found on Google Fonts? Here are steps that you can follow if you have permission to use the fonts:

  1. Open the company's homepage in a browser with DevTools open.
  2. In the Network tab, filter by "Font" (or by extension: woff2, woff, ttf, otf).
  3. Hard-reload the page and click around (pricing, blog, careers) — some weights only load on specific routes.
  4. For each captured font URL: right-click → Save As to download the file locally.
  5. View the page's CSS (DevTools → Sources, or curl the stylesheet URLs) and copy out the matching @font-face declarations. Rewrite each src: url(...) to point to your local file path.
