Description
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.

Could you build this?
Partial While basic calendar sync and rule triggers are vibe-codeable, multi-provider bidirectional sync (Google, Microsoft Graph, CalDAV/Apple) with edge-case resolution, timezone normalization, iCal invite generation, and recurring event RFC-5545 compliance is notoriously complex.
What it would actually take: Requires an event-driven worker queue (e.g., Temporal, BullMQ) handling webhooks and polling across Google Calendar, Microsoft Graph, and CalDAV APIs. The hard part is building an RFC 5545-compliant recurrence rule engine and resolving conflicts, idempotency, and invite delivery without bouncing or infinite sync loops.
