Amplitude vs Semrush

Amplitude and Semrush (We do love open source and have an opportunity to make it better from now.) both appear on the Smoower Developer Ecosystem Index.

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

Amplitude carries 3,167 GitHub stars across 151 public repos, with 39 repositories active in the last 90 days and 23 external contributors on record. Semrush shows 454 stars across 11 public repos, 2 active in the last 90 days and 7 external contributors.
