Programmable calendar sync for humans and AI agents
CalendarPipe syncs Google, Outlook, and Apple calendars through programmable pipes that filter, transform, and route events. Build pipes visually, describe them in plain English with AI, or write TypeScript. Events flow as real invitations — no OAuth needed on the recipient side. AI agents get a REST API, CalDAV, and MCP server to spin up their own calendars and send invites.
CalendarPipe advertises 2-minute setup with no credit card required for the free plan. Events arrive as normal calendar invitations—no app installs or user sign-ups needed on the receiving end, making it accessible to non-technical users.
CalendarPipe creates pipes that filter and sync events between Google Calendar, Outlook, and Apple Calendar. Users can set rules to automatically copy family events (like school pickups or doctor visits) to their work calendar, eliminating scheduling conflicts without manual intervention.
CalendarPipe offers visual builder, code editor, and AI-powered rule generation to create custom pipes. Users can filter events by day, duration, keywords, or custom logic, and transform event details before syncing—enabling granular control over what information flows between calendars.
CalendarPipe's Agentic Hosted Calendars feature spins up a calendar with a real email address and API key. AI agents can book meetings via three API calls, and attendees receive standard email invitations—no OAuth, no user credential access required.
CalendarPipe's invitation-based delivery works behind corporate firewalls by sending events as standard email invitations rather than requiring OAuth permissions. This bypasses IT restrictions while maintaining full calendar synchronization.
