Cronofy provides a calendar sync API and embeddable scheduling tools for Google, Outlook, and Apple Calendar; compare its 2026 pricing plans here.
Cronofy is a calendar synchronization API and scheduling platform founded in 2014 by engineers Adam Bird and Garry Shutler, headquartered in Nottingham, UK, with additional offices in London and Amsterdam. It provides the calendar infrastructure that other products build scheduling features on top of, connecting to Google Calendar, Microsoft 365/Outlook, Apple Calendar, and Exchange.
The company serves two audiences: end users who book meetings through Cronofy's embeddable Scheduler links, and developers who integrate Cronofy's Calendar API/SDK directly into their own product, such as an applicant tracking system or telehealth app that needs real-time availability and booking.
Real-time, two-way calendar sync keeps busy/free status and new bookings accurate across a user's actual calendar the moment they change, rather than relying on periodic polling.
Group and round-robin scheduling supports panel interviews and team-based booking, while configurable availability rules let organizations define working hours, buffers, and booking limits.
Native integrations with recruiting and HR tools such as Greenhouse, Lever, SmartRecruiters, Zoom, Zendesk, HubSpot, and Okta make Cronofy especially popular for interview scheduling.
Cronofy's Scheduler plans start at $15 per active seat per month (Team), scaling to $799/month billed annually for Business (up to 50 active seats plus Scheduler API access), with a custom Enterprise tier above that. Billing follows a dynamic 'pay for active users' model based on actual monthly usage rather than provisioned seats.
Separately, API-only pricing for developers starts around $139/month (Starter) and scales through Emerging (~$819/month) and Growth (~$2,399/month) tiers based on usage volume, with a custom Strategic tier for the largest integrators. A free trial is available.
