Build with Cronofy

Read as Markdown

Cronofy is the temporal infrastructure layer for product teams building scheduling, meeting coordination, and AI agent workflows at scale. A 99.99% uptime guarantee and industry-leading security and privacy controls make it infrastructure you can rely on.

The Temporal Grid unifies calendar connectivity, user availability, the full scheduling lifecycle, and meeting intelligence into a single foundation — so teams can build on it once and expand as their product evolves.

Build on the Temporal Grid #

Cronofy provides modular capabilities built on the same high-performance, reliable infrastructure. Use them independently or together.

Embedded Scheduler #

The fastest way to add scheduling to your product. Embed a fully managed scheduling experience with minimal code and Cronofy handles the rest.

Fully managed scheduling for users with Cronofy Accounts to control working hours, conferencing, and preferences. Teams can create complex scheduling rules and workflows.

The Scheduler API lets you embed this functionality directly in your application. Embedding requires only a few lines of code and some simple steps.

Cronofy API #

Cronofy’s API endpoints and UI elements give you full control over scheduling workflows — even the most complex, multi-person, multi-stage processes.

End-users authorize your application to access their calendars through Cronofy. Cronofy then brokers that access to provide:

  • A real-time synchronization engine that tracks activity on connected calendars.
  • An authorization model that supports linking multiple calendar accounts.
  • A permissions model that ensures applications only get access to the data they need.
  • A single API for interacting with calendar data across all connected calendar service providers.
  • Calendar Webhooks for tracking changes.
  • Availability APIs to support even the most complex scheduling requirements.
  • Embeddable UI Elements to fast-track development and benefit from UX best practices learned across thousands of applications.

Meeting Agents #

A single API to record, transcribe, and summarize meetings across Zoom, Google Meet, and Microsoft Teams. Runs entirely on Cronofy’s infrastructure with no third-party subprocessors. The agent name and avatar are fully configurable to match your product. Supports 30+ languages, with data processed and stored in your selected region.

Deploy standalone via a join URL, or integrate so a Meeting Agent attaches directly to a calendar event scheduled through Cronofy — staying aligned if the meeting is updated or rescheduled.

MCP Server #

Cronofy’s MCP server enables AI agents to access temporal infrastructure directly: scheduling, availability, and meeting context without human intervention. Build agentic scheduling workflows on the same Temporal Grid that powers all Cronofy products.
