Why look for an alternative to Calendly?

Calendly is a scheduling tool: you share a link, and people pick a time that fits your calendar, without emails back and forth.

People look for an alternative because the free plan allows only one type of meeting, and paid plans are charged per user, which gets expensive for teams that all take bookings. Features such as round-robin team scheduling and removing Calendly's branding sit on higher plans. A self-hosted Cal.com has unlimited meeting types and team scheduling with no price per user, and keeps your clients' details on your own server.
