⭐ Star History

Tip

Migrating here from star-history.com? You're at the right place. GitHub's Stargazer API shutdown doomed the original project, but this fork keeps star history alive using our own data. We are the only service that's simple to use and doesn't beg for an API token.

👇 THIS is a live chart. Head towards star-history.dera.page to get started.
