Ahrefs vs Yoast

Ahrefs (BTW we use OCaml) and Yoast (This is where the Yoast.com team shares its public code: from our WordPress plugins to other small projects.) both appear on the Smoower Developer Ecosystem Index.

Yoast (rank #209) holds a narrow lead over Ahrefs (rank #401) on the overall Smoower ecosystem score (49 vs 41). The gap of 8 points reflects composite signals across code, docs, community and reach.

On code quality (the state of repositories, tests, releases and polish), Yoast is clearly ahead of Ahrefs. On education (docs, guides and learning material for developers), Yoast is ahead of Ahrefs. On community (issue response, PR reviews and discussion health), Yoast is slightly ahead of Ahrefs. On reach (how visible the ecosystem is beyond its own repos), Ahrefs is slightly ahead of Yoast. On momentum (release cadence and how fast the ecosystem moves), Ahrefs is ahead of Yoast.

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. Yoast shows 3,439 stars across 78 public repos, 12 active in the last 90 days and 21 external contributors.
