About

Cal ID is a cloud-based scheduling platform designed to streamline appointment booking and manage calendars for professionals and teams. The tool offers unlimited scheduling links, full customization of booking pages, and deep integrations with major apps like Google Calendar, Outlook, Zoom, Slack, and payment systems. It allows hosts to create multiple event types with different durations and rules, set up round-robin or collective scheduling for team availability, and automate reminders and follow-ups to reduce no-shows. The software supports multi-calendar sync so users can manage work, personal, and shared calendars in one place, and provides analytics on bookings, attendance, and conversion trends. Cal ID positions itself as a no-cost alternative with a free-forever plan offering key functionalities and an open source foundation that allows self-hosting or contributions.
