edX vs Yoast

edX (Online learning at https://edx.org, powered by the Open edX platform https://openedx.org) 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 edX (rank #338) on the overall Smoower ecosystem score (49 vs 43). The gap of 6 points reflects composite signals across code, docs, community and reach.

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

edX carries 392 GitHub stars across 250 public repos, with 52 repositories active in the last 90 days and 22 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 8.8x larger, which usually shows up in downstream signals like inbound issues and third party integrations.

edX is the stronger read for anyone weighting reach. Yoast looks better where education is the deciding factor. The table below breaks the scores down pillar by pillar; the linked profiles cover the underlying repos, docs and community signals in full.
