Booking links that show your free time from a connected calendar, with team scheduling, routing forms and reminders.
Calendly is a scheduling tool built around a booking link. You connect your calendar, set the hours you take meetings and the types of meeting you offer, and share the link. The person booking sees only the times you are free and picks one, and the event lands in both calendars.
Beyond one-to-one links it handles round-robin and collective meetings for teams, buffers between meetings, limits per day, intake questions and reminder emails. Routing forms can send a visitor to a different person or meeting type based on their answers.
It connects to Google and Microsoft calendars and to video tools such as Zoom, Teams and Google Meet. Check which features sit on the free plan and which need a paid seat before you build your team setup around it.
