HubSpot (rank #93) holds a modest lead over Semrush (rank #317) on the overall Smoower ecosystem score (56 vs 44). The gap of 12 points reflects composite signals across code, docs, community and reach.

On community (issue response, PR reviews and discussion health), Semrush is slightly ahead of HubSpot. On reach (how visible the ecosystem is beyond its own repos), HubSpot is clearly ahead of Semrush. On momentum (release cadence and how fast the ecosystem moves), HubSpot is ahead of Semrush.

HubSpot carries 53,481 GitHub stars across 381 public repos, with 35 repositories active in the last 90 days and 4 external contributors on record. Semrush shows 454 stars across 11 public repos, 2 active in the last 90 days and 7 external contributors.
