Calendox vs SyncPenguin: Pricing, Quotas and Tenant Sync

Questions

How does Calendox pricing differ from SyncPenguin's?

Calendox prices per user, while SyncPenguin prices tiers of active sync flows. On SyncPenguin's pricing page, a sync flow is one pair of calendars synced one way or both ways. Each tier's monthly update quota is 1,000 updates for every flow it allows, shared across all your flows. From 25 flows, cheaper tiers with smaller quotas are also offered. SyncPenguin's prices exclude VAT.

Calendox Personal plans are priced per user and Business plans per seat. Business seats cost the same as the matching Personal plan. Each plan caps how many calendars you connect and how many syncs you run. Enterprise is billed for each calendar imported from a secondary tenant, while master-tenant calendars are free. Current prices are on the Calendox pricing page, in US dollars, and taxes may apply.

The pricing table above compares the same scenario on both sides. For one person with one pair of calendars, Calendox Basic costs less than SyncPenguin's 2-flow plan on both billing cycles. For the team of 10 and the 100 tenant pairs, SyncPenguin's flow tiers cost less.

Does either product limit how many changes it syncs?

Calendox Basic, Standard and Premium include unlimited synced events, while SyncPenguin plans include a monthly update quota. On Calendox, the limits are the calendars and syncs each plan allows. SyncPenguin counts an update when it actually changes and syncs a record, and it doesn't count merges or checks that find no change. Its pricing page says that if usage goes over the quota, it notifies you and gives you time to upgrade. It also says it never changes your plan automatically or charges for overages.

How quickly do changes reach the other calendar?

Calendox syncs Google and Microsoft calendars in real time (how Calendox sync works). Changes typically arrive in under 30 seconds from Google Calendar and under 60 seconds from Microsoft Outlook. These are typical times, not guarantees.

SyncPenguin describes sync between its Google and Outlook connectors as near-instant in its Microsoft 365 and Google Workspace guide. For sync between Microsoft 365 tenants, its tenant-to-tenant guide recommends the Outlook connector for near-instant syncing. Its other calendar connectors check for changes every 10 minutes by default and every 5 minutes at the shortest, and ICS feeds every 30 minutes at the shortest.

How does Microsoft 365 tenant-to-tenant sync work on each?

Both run admin-managed sync between Microsoft 365 tenants, and on both, employees don't connect their own calendar accounts. They differ in how calendars are paired.

With Calendox Enterprise:

1. An administrator of each tenant consents once for the whole organization.
2. The master tenant is the first one you connect, and its calendars are free. Every calendar imported from a secondary tenant takes one seat.
3. Calendox pairs master- and secondary-tenant calendars automatically when both the email username (the part before the @) and the calendar name match, ignoring case. Anything left unmatched can be paired by hand or by CSV import.

Enterprise accounts are for tenant sync only. They don't include the unified calendar or booking pages, and they connect Microsoft 365 tenants only.

On SyncPenguin, tenant-to-tenant sync through domain-wide access needs admin access in both tenants, and users don't connect their own accounts. Admins add users by entering their email addresses in each tenant, one at a time, in bulk or by CSV import, or let a user group in each tenant fill in the list automatically. SyncPenguin runs admin-managed sync for Google Workspace too, through a Google service account an admin creates, including between a Microsoft 365 and a Google Workspace organization (Microsoft 365 and Google Workspace guide). SyncPenguin also offers a simpler sync between two calendars that doesn't need admin access.

Which Calendox accounts include a unified calendar and booking pages?

Calendox Personal and Business accounts include both. Neither is listed on SyncPenguin's website, whose web dashboard is for setting up, monitoring and troubleshooting syncs.

• Unified calendar: see all your connected Google and Microsoft calendars in one working calendar, in six views. New events and edits are written back to the original calendar.
• Booking pages: a booking page checks every connected calendar for conflicts by default, so bookers see only open slots. Each booking can get a meeting link. Google Meet needs a Google destination calendar, and Microsoft Teams a work or school Microsoft one. Zoom links work with any calendar once Zoom is connected. Basic includes 2 booking pages, and Standard and Premium include unlimited pages, with fair-use limits.

How do the free trials compare?

Calendox offers a 14-day free trial with no credit card, and SyncPenguin advertises the same. Calendox Personal and Business trials run at Premium-level limits, and on a Business team every member uses their own trial until the team subscribes. An Enterprise trial syncs up to 5 imported secondary-tenant calendars in total.

When a Calendox trial ends without a subscription, syncs pause. Your connections and settings are kept, and syncing resumes when you subscribe. On Business, it resumes once you hold a license from the team's subscription. SyncPenguin's FAQ says its trial can be extended on request.
