On education (docs, guides and learning material for developers), UserTesting is slightly ahead of Ahrefs. On community (issue response, PR reviews and discussion health), Ahrefs is clearly ahead of UserTesting. On reach (how visible the ecosystem is beyond its own repos), UserTesting is ahead of Ahrefs.

Ahrefs carries 1,303 GitHub stars across 171 public repos, with 28 repositories active in the last 90 days and 7 external contributors on record.
