Why it ranks here
Health score explained
SOGo scores 83/100, #4 of 20 in Groupware: 39 commits in the last 90 days earn 35.0 of 35 points, the latest release (SOGo-5.12.12, 17 days ago) earns 25.0 of 25, 2,181 stars add 13.4 of 20, an active, unarchived repository keeps 10 and no advertised Docker image leaves the final 10 unclaimed.
