SavvyCal rethinks the scheduling link from the recipient’s side: they can overlay their own calendar on top of yours and pick a slot that works for both, and you can rank your availability so better times get chosen more often. Team features cover round-robin and collective scheduling.
It suits people who send a lot of scheduling links and care how receiving one feels. It is a focused, bootstrapped product — Calendly has the bigger team, integration catalog and free plan.
