Discourse (rank #189) holds a modest lead over Buffer (rank #455) on the overall Smoower ecosystem score (50 vs 39). The gap of 11 points reflects composite signals across code, docs, community and reach.

On education (docs, guides and learning material for developers), Buffer is slightly ahead of Discourse. On community (issue response, PR reviews and discussion health), Discourse is ahead of Buffer. On reach (how visible the ecosystem is beyond its own repos), Discourse is ahead of Buffer. On momentum (release cadence and how fast the ecosystem moves), Discourse is clearly ahead of Buffer.

Buffer carries 11,181 GitHub stars across 196 public repos, with 4 repositories active in the last 90 days and 0 external contributors on record. Discourse shows 55,678 stars across 620 public repos, 90 active in the last 90 days and 44 external contributors.
