Can you name the Most-starred R repositories?

This quiz asks you to name all ten entries in Most-starred R repositories. You get three minutes and ten empty slots; type a name, press enter, and if it matches an entry in the current top 10 the slot fills in with its rank and value. Accents, punctuation and letter case are ignored, a small typo is tolerated on longer names, and short forms that the data source itself uses are accepted. You can keep guessing (up to 60 attempts) until the clock runs out or every slot is full.

The answers are the live ranking as it stands, captured on 2026-10-29 from GitHub and measured by Stars. Because the ranking refreshes on a schedule, the answer set can change from one day to the next, which makes the quiz worth replaying. When you finish, the entries you missed are revealed on the ranking page so you can learn them for next time.

Be among the first to set a score. When enough people have played, this page shows the average score and the entry most players miss.

Your result lives at an unlisted link that you can share anywhere, and there is no account to create. We keep the guesses, the score and the time taken, not who you are; the privacy policy lists exactly what is stored. The result page hides the entries you did not find so that whoever you challenge still has to work for their score.

This quiz belongs to the software and developer tools category. Top10Earth never estimates or edits a value: each number is fetched from its source, hashed, stored and ranked by software, then checked by a quality gate before it is published. If a refresh fails the gate, the previous snapshot stays live and the problem is reviewed by a person.
