CalendarBridge caps how many calendars you connect. CalendarPipe doesn't.

CalendarBridge prices by how many calendars you connect — 2 on Basic, 5 on Premium, 8 on Pro at $32/month billed annually. Every account you add pushes you toward the next tier.

CalendarBridge connects each calendar through OAuth. To put events on someone else's calendar, that calendar has to be OAuth-connected too. There's no way to simply send events to a calendar you don't control.

CalendarBridge filters by category and color and lets you set privacy rules for event details. That covers simple cases, but you can't write conditional logic, transform titles, or filter on arbitrary fields.

CalendarBridge gives you a 7-day free trial, then every tier is paid. There's no permanent free plan to fall back on when your needs are light.

CalendarPipe can deliver synced events as standard calendar invitations. The receiving calendar doesn't need to be connected or authorized — unlike CalendarBridge, where every calendar must be OAuth-linked. It even works behind corporate firewalls, because an invitation is just email.

Write JavaScript gate functions that run in a secure sandbox: filter events by any field, rewrite titles, strip attendees, route conditionally, skip weekends. Prefer not to code? Use the visual builder or describe the rule in plain English.

CalendarPipe Pro is $4/month for unlimited calendars and rules — no tiers that climb as you connect more accounts. The free plan (2 calendars, 1 rule) never expires, so you're never forced onto a paid tier.

Beyond personal sync, CalendarPipe can host calendars an AI agent owns outright — its own email address, driven by a REST API. There if you ever need it; nothing to think about if you don't.
