Calendly

The platform lets users publish a scheduling link that reflects real‑time availability from up to six connected calendars, allowing invitees to pick meeting times without email exchanges. Users can define detailed availability rules, buffers, and custom event types, and the service can sync with video‑conferencing tools to automatically generate meeting links for virtual or in‑person sessions.

It supports integration with a wide range of productivity suites, including Google Workspace and Microsoft 365, and offers more than a hundred additional connectors to embed scheduling on websites, landing pages, or emails. The tool is positioned for both individual users and larger organizations, with a free tier for personal use and paid plans that add team‑level features and enterprise‑grade security.

The service is marketed as a stable, security‑focused solution adopted by many large enterprises, and it aims to reduce the back‑and‑forth of appointment setting while keeping calendar data synchronized across connected applications.
