The Cal.com Developer Scheduler

A developer, indie maker, or privacy-conscious professional who uses Cal.com because they either self-host it or value that they can. They were on Calendly and either hit a pricing ceiling, wanted customization Calendly doesn't allow, or made a deliberate decision about data ownership. Cal.com is open source. They can read the code. They can modify it if they need to. The fact that this is possible — even if they never do it — matters to them in a way that influences their tooling choices.

The Cal.com Scheduling Power User

A consultant, agency owner, or team lead who uses Cal.com because Calendly was too simple for their scheduling needs. They manage round-robin scheduling for a team, paid consultation bookings, multi-timezone availability, and custom booking forms that collect information before the meeting. They chose Cal.com because it's open-source, self-hostable, and extensible in ways Calendly's paid tiers can't match. They are the scheduling architect for their team.
