edX vs Sage

edX (Online learning at https://edx.org, powered by the Open edX platform https://openedx.org) and Sage both appear on the Smoower Developer Ecosystem Index.

edX (rank #338) holds a modest lead over Sage (rank #625) on the overall Smoower ecosystem score (43 vs 33). The gap of 10 points reflects composite signals across code, docs, community and reach.

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

edX carries 392 GitHub stars across 250 public repos, with 52 repositories active in the last 90 days and 22 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 Sage's footprint is roughly 5.6x larger, which usually shows up in downstream signals like inbound issues and third party integrations.

edX is the stronger read for anyone weighting momentum. Sage looks better where community 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.
