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

SlackAPI (rank #47) holds a modest lead over edX (rank #338) on the overall Smoower ecosystem score (61 vs 43). The gap of 18 points reflects composite signals across code, docs, community and reach.

On code quality (the state of repositories, tests, releases and polish), SlackAPI is clearly ahead of edX. On education (docs, guides and learning material for developers), SlackAPI is ahead of edX. On community (issue response, PR reviews and discussion health), SlackAPI is ahead of edX. On reach (how visible the ecosystem is beyond its own repos), edX is clearly ahead of SlackAPI. On momentum (release cadence and how fast the ecosystem moves), SlackAPI is clearly 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. SlackAPI shows 17,894 stars across 37 public repos, 19 active in the last 90 days and 39 external contributors.
