Amplitude vs Stream

Amplitude and Stream (Build scalable in-app chat, feeds, and live video with AI moderation capabilities in hours, not weeks.) both appear on the Smoower Developer Ecosystem Index.

Amplitude (rank #93) holds a modest lead over Stream (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 slightly ahead of Stream. On education (docs, guides and learning material for developers), Stream is ahead of Amplitude. On community (issue response, PR reviews and discussion health), Stream is slightly ahead of Amplitude. On reach (how visible the ecosystem is beyond its own repos), Stream is slightly ahead of Amplitude. On momentum (release cadence and how fast the ecosystem moves), Stream is ahead of Amplitude.

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. Stream shows 35,664 stars across 487 public repos, 84 active in the last 90 days and 44 external contributors. The star gap on its own does not decide the comparison, but Stream's footprint is roughly 11.3x larger, which usually shows up in downstream signals like inbound issues and third party integrations.

Amplitude is the stronger read for anyone weighting code quality. Stream looks better where education 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.
