Stream vs Semrush

Stream (Build scalable in-app chat, feeds, and live video with AI moderation capabilities in hours, not weeks.) 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.

Stream and Semrush sit at essentially the same overall ecosystem score (44), which is unusual and worth reading through the pillars below.

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

Stream carries 35,664 GitHub stars across 487 public repos, with 84 repositories active in the last 90 days and 44 external contributors on record. Semrush shows 454 stars across 11 public repos, 2 active in the last 90 days and 7 external contributors. The star gap on its own does not decide the comparison, but Stream's footprint is roughly 78.6x larger, which usually shows up in downstream signals like inbound issues and third party integrations.

Stream is the stronger read for anyone weighting momentum. Semrush looks better where reach 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.
