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

Affinity carries 4 GitHub stars across 40 public repos, with 1 repositories active in the last 90 days and 2 external contributors on record. Kustomer shows 15 stars across 19 public repos, 6 active in the last 90 days and 4 external contributors.
