Discourse vs Zendesk

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

Zendesk (rank #165) holds a narrow lead over Discourse (rank #190) on the overall Smoower ecosystem score (51 vs 50). 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), Discourse is slightly ahead of Zendesk. On education (docs, guides and learning material for developers), Discourse is slightly ahead of Zendesk. On community (issue response, PR reviews and discussion health), Zendesk is slightly ahead of Discourse. On reach (how visible the ecosystem is beyond its own repos), Zendesk is ahead of Discourse. On momentum (release cadence and how fast the ecosystem moves), Discourse is clearly ahead of Zendesk.

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. Zendesk shows 12,427 stars across 891 public repos, 87 active in the last 90 days and 10 external contributors. The star gap on its own does not decide the comparison, but Discourse's footprint is roughly 4.5x larger, which usually shows up in downstream signals like inbound issues and third party integrations.
