Introduction

CalendarPipe syncs calendars across Google, Microsoft, and Apple/CalDAV through pipes. Each pipe copies events from one calendar to another under a rule that decides which events flow and how they are transformed along the way.

Capabilities

• Calendar sync — connect Google, Microsoft, and Apple (CalDAV) calendars and route events between them.
• Rules — filter and transform events with a visual builder, templates, AI, or TypeScript that runs in an isolated JavaScript sandbox.
• Booking pages — share a link where people book your free time, with availability filtered by rules.
• Hosted calendars — calendars that live entirely within CalendarPipe, accessible over CalDAV and ICS.
• REST API — manage calendars, events, and invitations programmatically.
• Agent workflows — AI agents can create events, send invitations, and respond to scheduling requests.
