How we rank

The Google Fonts Developer API gives us a license-safe baseline: the official popularity order for open-source families. A job runs every Monday and stores that week's ranking in our own database, so the leaderboard is a real, queryable history — not a one-off snapshot.

Every open-source family on Fontsource is published as an npm package. We read the public npm download counts each week, which shows how often a typeface is actually installed into real projects — not just previewed. Free, public data, refreshed by the same Monday job.

For open-source foundries we track live star counts from each font's own repository, refreshed by the same weekly job — so fast-moving indie projects can climb before they reach mainstream catalogues.

Signed-in people upvote fonts, one vote per person per font. Votes are counted the moment they land: the leaderboard listens for changes and reorders itself in real time, with a small seed score so unranked indie work can still show up.
