Discourse vs Sage

Discourse (The 100% open source discussion platform built for the next decade of the Internet.) and Sage both appear on the Smoower Developer Ecosystem Index.

Discourse (rank #189) holds a modest lead over Sage (rank #625) on the overall Smoower ecosystem score (50 vs 33). The gap of 17 points reflects composite signals across code, docs, community and reach.

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

Discourse carries 55,678 GitHub stars across 620 public repos, with 90 repositories active in the last 90 days and 44 external contributors on record. Sage shows 2,180 stars across 122 public repos, 6 active in the last 90 days and 22 external contributors. The star gap on its own does not decide the comparison, but Discourse's footprint is roughly 25.5x larger, which usually shows up in downstream signals like inbound issues and third party integrations.

Discourse is the stronger read for anyone weighting momentum. Sage makes more sense for teams already using its adjacent tools. The table below breaks the scores down pillar by pillar; the linked profiles cover the underlying repos, docs and community signals in full.
