CalendarPipe
Programmable calendar sync that connects Google, Outlook, and Apple calendars through rules you build visually, in plain English, or in code — plus a real calendar API for AI agents.

Description
If you've ever double-booked yourself because your work calendar and your personal calendar don't talk to each other, CalendarPipe is built to fix exactly that: it connects your Google, Outlook, and Apple calendars and lets you set up simple rules — like 'copy my work meetings into my personal calendar as busy blocks, but hide the details' — so everything stays in sync without you copy-pasting events by hand.
Under the hood, those rules are 'pipes' you can build visually, describe in plain English (AI turns your description into a working rule), or write directly in TypeScript for full control. It also ships infrastructure for AI agents: a REST API, CalDAV support, and an MCP server let an agent spin up its own calendar and send real email invites to real people — no OAuth handshake required on the recipient's side, which matters in locked-down corporate environments where external API access is usually blocked.
💬 Our review
The short version: if calendar sync tools have always felt like a black box, CalendarPipe's pitch — visual pipes, or describe-it-in-English rules, or raw TypeScript if you want it — gives you three levels of control depending on how deep you want to go, and the entry price is low.
Against basic sync tools like SyncThemCalendars, CalendarPipe's programmability (filtering, transforming, routing, not just mirroring) is a real differentiator, especially for anyone who needs conditional logic rather than a blind copy. The AI-agent angle — giving bots their own real, invite-sending calendars via API/MCP — is more niche and mainly useful if you're actually building agentic workflows, not a reason to sign up for personal calendar sync. At $4/month (or $40/year) for the unlimited Pro tier, it's cheap enough that the free tier's 2-connection, 15-minute-interval limit is really just a trial; most people who need multi-calendar sync will hit that ceiling fast and should budget for Pro from the start. <!-- ai-generated -->
