Cal.diy scores 81/100, #7 of 9 in Booking and Scheduling: 26 commits in the last 90 days earn 30.3 of 35 points, the latest release (v6.2.0, 8 months ago) earns 22.1 of 25, 49,538 stars add 18.8 of 20, an active, unarchived repository keeps 10 and no advertised Docker image leaves the final 10 unclaimed.
