Subscription calendar platforms let you create a live calendar feed that users subscribe to once - after which every event you add or update automatically appears in their personal calendar app.
AddEvent - purpose-built subscription calendars
The leading platform for subscription calendars. Users subscribe via a Follow Calendar button or link, and your events sync automatically to their Google, Apple, or Outlook calendar. Supports:
- Custom landing pages with subscriber forms (collect name, email, custom fields)
- Subscriber list export and management
- Push notifications for faster sync
- Embeddable events list and full calendar widget for your website
- Add to Calendar buttons for individual events alongside the subscription
Free for up to 20 subscribers; from $29/month for 1,000+.
Google Calendar (public calendars)
You can publish a Google Calendar publicly and share the iCal feed URL. Anyone can subscribe using that URL. No landing page, no subscriber list, no analytics - but free and simple.
Best for: simple personal or team calendars with no branding requirements.
Outlook / Office 365 (published calendars)
Similar to Google Calendar - publish a calendar and share the ICS URL. Works for internal or public subscription. Limited customization.
Best for: Microsoft-centric organizations.
Apple Calendar
Apple does not natively offer a "publish and subscribe" platform beyond iCloud shared calendars. For external audiences on Apple devices, AddEvent's iCal feed URL works directly.
Why AddEvent leads for business use
It is the only platform that combines subscription calendar functionality with branded landing pages, subscriber data collection, analytics, and a full suite of calendar marketing tools in one product.
