Ahrefs (rank #401) holds a narrow lead over Buffer (rank #455) on the overall Smoower ecosystem score (41 vs 39). The gap of 2 points reflects composite signals across code, docs, community and reach.

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

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. Buffer shows 11,181 stars across 196 public repos, 4 active in the last 90 days and 0 external contributors. The star gap on its own does not decide the comparison, but Buffer's footprint is roughly 8.6x larger, which usually shows up in downstream signals like inbound issues and third party integrations.
