Plan your first step with calcom/cal.diy

calcom/cal.diy looks like a candidate for web applications (self-hostable); U=25: no ministry features; pure general-purpose scheduling — a church could run it for appointments but nothing is ministry-modeled.

Skill: setup may still need a technically comfortable helper — that is normal for open source.

Connection prompt

I am choosing open-source software for my ministry using Refinry, a review site. Read Refinry’s plain-language agent feed — https://refinry.dev/docs.md — then help me evaluate calcom/cal.diy: summarize the Trust Score, the strongest and weakest dimensions, and any caution flags it cites. Give me one small first step I can complete this week, and tell me honestly if this looks like more than I can handle.

I am choosing open-source software for my ministry using Refinry, a review site. Read Refinry’s public review of calcom/cal.diy (https://refinry.dev) and help me assess it for using calcom/cal.diy for web applications (self-hostable) in my ministry. Summarize the Trust Score, the strongest and weakest dimensions, and any caution flags it cites, separating reviewed evidence from what still needs verification. Give me one small first step I can complete this week, and tell me honestly if this looks like more than I can handle.
