Discourse vs edX

Discourse (The 100% open source discussion platform built for the next decade of the Internet.) and edX (Online learning at https://edx.org, powered by the Open edX platform https://openedx.org) both appear on the Smoower Developer Ecosystem Index.

Discourse (rank #190) holds a narrow lead over edX (rank #338) on the overall Smoower ecosystem score (50 vs 43). The gap of 7 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 edX. On education (docs, guides and learning material for developers), Discourse is ahead of edX. On community (issue response, PR reviews and discussion health), Discourse is ahead of edX. On reach (how visible the ecosystem is beyond its own repos), edX is slightly ahead of Discourse. On momentum (release cadence and how fast the ecosystem moves), Discourse is clearly ahead of edX.

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. edX shows 392 stars across 250 public repos, 52 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 142.0x larger, which usually shows up in downstream signals like inbound issues and third party integrations.

Discourse is the stronger read for anyone weighting momentum. edX looks better where reach 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.
