edX vs Open edX

edX (Online learning at https://edx.org, powered by the Open edX platform https://openedx.org) and Open edX (The community-driven, open-source project powering edX.org and thousands of other online education sites around the world.) both appear on the Smoower Developer Ecosystem Index.

edX (rank #338) holds a narrow lead over Open edX (rank #372) on the overall Smoower ecosystem score (43 vs 42). The gap of 1 points reflects composite signals across code, docs, community and reach.

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

edX carries 392 GitHub stars across 250 public repos, with 52 repositories active in the last 90 days and 22 external contributors on record. Open edX shows 10,654 stars across 186 public repos, 100 active in the last 90 days and 91 external contributors. The star gap on its own does not decide the comparison, but Open edX's footprint is roughly 27.2x larger, which usually shows up in downstream signals like inbound issues and third party integrations.

edX is the stronger read for anyone weighting reach. Open edX 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.
