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

CalendarBridge syncs calendars across three paid tiers that cap how many you connect, with rules set by category and privacy toggles. CalendarPipe gives you programmable JavaScript rules, events delivered as plain calendar invitations — no OAuth on the receiving calendar — and a plan that's free forever.

Where CalendarBridge falls short

CalendarBridgehas strengths, but here's what users run into.

Your plan is capped by calendar count

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.

OAuth required on every calendar — even the one you sync to

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.

Rules are toggles, not logic

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.

No free plan — just a 7-day trial

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.

Why teams switch to CalendarPipe

Deliver to any calendar — no OAuth required

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.

Rules are code, not checkboxes

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.

Flat price, no calendar cap

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.

Calendars for your AI agents, too

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.

When CalendarBridge is the better choice

We'd rather you pick the right tool than the one we sell.

You want meetings booked over email

CalendarBridge's AI assistant books meetings when you CC it on an email thread. CalendarPipe's AI only writes sync rules from plain-English descriptions — it doesn't coordinate meetings. If that workflow is core to you, CalendarBridge has it and CalendarPipe doesn't.

You want scheduling pages and a unified calendar app

CalendarBridge bundles scheduling pages and a single view of all your calendars with its sync. CalendarPipe includes neither. Replacing that means pairing it with Cal.com, Calendly, or whatever calendar app you already like.

Switching from CalendarBridge is low-risk

There's no data to move and no hard cutover. Run CalendarPipe alongside CalendarBridge, then switch over only once you're ready.

  1. 1

    Run both side by side

    CalendarPipe and CalendarBridge don't conflict. Keep CalendarBridge running while you set CalendarPipe up and test it — there's no rush to switch.

  2. 2

    Nothing to export or import

    There's no data migration. CalendarPipe reads from the calendars you connect, so your events stay where they are. You're recreating sync rules, not moving data.

  3. 3

    Live in about two minutes

    Connect your calendars, pick a template or describe a rule in plain English, and you're syncing. Cancel CalendarBridge once CalendarPipe does what you need.

Frequently asked questions

Common questions about switching from CalendarBridge.

Can I run CalendarPipe and CalendarBridge at the same time?

Yes. They operate independently on your calendars, so you can keep CalendarBridge running while you set CalendarPipe up — and switch over only once you're happy with it.

Do I have to migrate any data from CalendarBridge?

No. There's nothing to export or import. CalendarPipe reads from the calendars you connect, so your existing events stay exactly where they are. Switching means recreating your sync rules, not moving data — and that takes about two minutes.

Which is cheaper, CalendarPipe or CalendarBridge?

CalendarPipe Pro is $4/month — $3.33/month billed annually — for unlimited calendars and sync rules. CalendarBridge ranges from $4/month for 2 calendars up to $32/month for 8, billed annually. CalendarPipe also has a free-forever plan; CalendarBridge offers a 7-day trial only.

Does CalendarPipe have an AI scheduling assistant like CalendarBridge?

Not the same kind. CalendarBridge's assistant books meetings when you CC it on an email. CalendarPipe's AI writes sync rules from plain-English descriptions — it doesn't coordinate meetings over email. If that workflow is core to you, CalendarBridge has it and CalendarPipe doesn't.

What about CalendarBridge's scheduling pages and unified calendar?

CalendarPipe doesn't include scheduling pages or a unified calendar app — it focuses on programmable sync. If you rely on those, you can keep a dedicated tool (like Cal.com or Calendly for scheduling) alongside CalendarPipe.
