CalendarPipe FAQ
Is there a free trial?
Yep, Pro has a 14-day free trial with full feature access. A card is collected upfront, but you are not charged until day 14, and you can cancel anytime in between. Not ready to commit? The free plan has no expiration date.
How do I create a pipe?
Most people start with the visual builder. Feeling fancy? Describe what you want in plain English and let AI build it. Prefer templates? There are those. Want full control? Write TypeScript in a code editor. All four modes produce the exact same pipe.
What calendars are supported?
Google Calendar, Microsoft Outlook (including Office 365 and Outlook.com), and Apple Calendar. More providers are on the roadmap.
How often do events sync?
Every 15 minutes on Free, every 5 minutes on Pro. New events, updates, and cancellations all propagate automatically, so you do not need to do a thing.
