On education (docs, guides and learning material for developers), Element is slightly ahead of Klaviyo. On community (issue response, PR reviews and discussion health), Element is slightly ahead of Klaviyo. On reach (how visible the ecosystem is beyond its own repos), Element is ahead of Klaviyo. On momentum (release cadence and how fast the ecosystem moves), Element is clearly ahead of Klaviyo.

Element carries 34,608 GitHub stars across 137 public repos, with 33 repositories active in the last 90 days and 97 external contributors on record. Klaviyo shows 573 stars across 117 public repos, 23 active in the last 90 days and 17 external contributors.
