Cronofy

Cronofy is scheduling infrastructure aimed at developers and product teams who need to embed calendar and booking workflows inside their own SaaS rather than send users to a standalone tool. At its core is a calendar API that syncs in real time with Google, Microsoft, Apple, and Exchange, surfacing accurate availability and preventing double-bookings across providers — and it queries provider APIs directly rather than storing event content, a privacy-preserving design.

On top of that data layer sit the scheduling products: real-time availability queries, one-on-one, panel, and multi-user scheduling with automatic conferencing links, timezone handling and recurring meetings, a pre-built Embeddable Scheduler UI for fast deployment, and a fully customizable White-Label API for teams that want to own the entire experience. Newer additions include meeting transcription with AI summaries and an MCP server for agentic workflows.

Compliance is a core selling point for its enterprise buyers: ISO 27001, 27701, and 27018, SOC 2 Type 2, and GDPR, CCPA, and HIPAA, with 99.99% uptime across six regional data centers. A free sandbox with 20 connected accounts requires no credit card, and production pricing scales with connected accounts and usage. Cronofy fits HR tech, healthcare, CRM, and EdTech companies embedding scheduling into their products — not end users looking for a booking page.
