“As a developer, I loved Cal.com's open-source approach and self-hosting option. But maintaining my own instance got old fast — every update meant downtime. Calendly just worked but felt overpriced for what we needed. SchedulingKit hit the sweet spot: modern API, no infrastructure headaches, and a free tier that actually covers a startup's needs.”
