Stream (rank #317) holds a modest lead over Heap (rank #569) on the overall Smoower ecosystem score (44 vs 35). The gap of 9 points reflects composite signals across code, docs, community and reach.

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

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. Heap shows 215 stars across 65 public repos, 6 active in the last 90 days and 1 external contributors.
