At a glance
| Criteria | SyncThemCalendars | Zapier |
|---|---|---|
| Focus | Purpose-built calendar sync | General-purpose automation across thousands of apps |
| Setup | Pick source, target and direction - about 2 minutes | Design and maintain Zaps for each calendar pair and direction |
| Updates and deletions | Mirrored automatically, duplicate-safe by design | Your Zaps must handle edited events, cancellations and loop prevention |
| Sync speed | Push-based: Google and Outlook changes propagate in moments | Polling intervals on most plans; faster triggers cost more |
| Cost model | Flat plans with unlimited events - a busy calendar costs the same | Per-task pricing - every synced event consumes quota |
| Privacy controls | Hide event details behind a 'Busy' block - built in | Build field mapping yourself in each Zap |

Why people pick SyncThemCalendars
The edge cases are the product
Copying a new event is the easy 10%. Updates, cancellations, recurring exceptions, moved occurrences and not re-copying your own copies are the hard 90% - and exactly what a dedicated sync engine handles for you.
Predictable cost on busy calendars
Task-based pricing punishes exactly the people who need sync most. With flat plans and unlimited events, a packed calendar costs the same as an empty one.
Two-way without loops
True two-way mirroring with loop protection is genuinely hard to assemble from triggers and actions. Here it's a toggle.
When Zapier might fit you better
If calendar events are one small piece of broader automations - CRM entries, Slack messages, spreadsheet rows - Zapier's breadth is unmatched. Plenty of our customers run both: SyncThemCalendars for sync, Zapier for everything else.

Recreate your syncs
Pick each source and target calendar, choose one-way or two-way, and set your privacy options. About 2 minutes per sync.
Turn off the old tool
Once you see events flowing, pause or cancel your previous tool so the two don't copy the same events side by side.
Frequently asked questions
What's wrong with syncing calendars via Zapier?
Nothing, if your needs are simple and low-volume. But event updates, deletions, recurring exceptions and two-way loops all need explicit handling in your Zaps, and per-task pricing scales with how busy your calendars are.
Can SyncThemCalendars and Zapier coexist?
Yes. Use SyncThemCalendars to keep the calendars themselves in sync, and Zapier for cross-app workflows around them. The two don't conflict.
How long does setup take?
About 2 minutes per sync: connect the accounts, pick source and target, choose the direction and privacy options. No logic to design.
Ready for calendar sync that just works?
Set up your first sync in 2 minutes. Google, Outlook and Apple iCloud, one-way or two-way, with your privacy protected.
