Ahrefs (rank #401) holds a narrow lead over Affirm (rank #485) on the overall Smoower ecosystem score (41 vs 38). The gap of 3 points reflects composite signals across code, docs, community and reach.

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

Affirm carries 207 GitHub stars across 116 public repos, with 9 repositories active in the last 90 days and 4 external contributors on record. Ahrefs shows 1,303 stars across 171 public repos, 28 active in the last 90 days and 7 external contributors. The star gap on its own does not decide the comparison, but Ahrefs's footprint is roughly 6.3x larger, which usually shows up in downstream signals like inbound issues and third party integrations.

Affirm is the stronger read for anyone weighting education. Ahrefs looks better where momentum 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.
