Semrush vs Yoast

Semrush (We do love open source and have an opportunity to make it better from now.) 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 Semrush (rank #317) on the overall Smoower ecosystem score (49 vs 44). The gap of 5 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 Semrush. On education (docs, guides and learning material for developers), Yoast is slightly ahead of Semrush. On community (issue response, PR reviews and discussion health), Yoast is slightly ahead of Semrush. On reach (how visible the ecosystem is beyond its own repos), Semrush is ahead of Yoast. On momentum (release cadence and how fast the ecosystem moves), Yoast is ahead of Semrush.

Semrush carries 454 GitHub stars across 11 public repos, with 2 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. The star gap on its own does not decide the comparison, but Yoast's footprint is roughly 7.6x larger, which usually shows up in downstream signals like inbound issues and third party integrations.
