What’s the difference?
Hetk: Purpose-Built Calendar Sync
Hetk solves one problem exceptionally well: keeping your Google, Outlook, and iCloud calendars in sync. It handles the complexity automatically, duplicates, conflicts, privacy controls, real-time updates.
Zapier: General-Purpose Automation
Zapier is a general workflow automation platform. You can build calendar sync workflows using Zaps (if/then rules), but it requires manual setup of triggers and actions, and you hit limitations like one-way sync, no duplicate detection, and one-way-per-Zap restrictions.
Where Hetk wins
Bi-directional sync, built-in
Hetk can sync both ways in one sync relationship: events made in either calendar appear in the other. With Zapier, you’d need to create separate Zaps for each direction, doubling complexity and cost.
Automatic duplicate detection
Hetk prevents duplicate events from appearing when syncing. Zapier doesn’t detect duplicates, if the same event syncs twice, you have to manage it manually.
Much simpler setup
Hetk: click “Add sync”, pick your calendars, set privacy, done. Zapier: create a Zap, configure triggers, map fields, manage errors, create reverse Zap for bi-directional, test, deploy. Hetk is 10x simpler.
Real-time sync
Hetk uses webhooks for real-time sync on every plan, including the trial.
Apple iCloud support
Hetk supports iCloud at the same price. Zapier doesn’t integrate with iCloud.
Privacy controls
Hetk lets you replace event details with “Busy”, flag copies with the provider’s private flag, and use title templates to label synced events. Zapier’s calendar automations don’t offer this granularity.
Cost
Hetk is $50/year for up to 8 sync pairs with unlimited calendars. Zapier’s Professional plan starts at $19.99/month billed annually ($239.88/year) or $29.99/month billed monthly. Its Team plan starts at $69/month billed annually ($828/year).
Where Zapier wins
Extreme flexibility
Zapier can connect calendars to anything, Slack, email, CRM, payment systems, etc. Hetk focuses on calendar-to-calendar sync only.
Existing Zapier users
If you already use Zapier for other workflows, calendar Zaps might feel natural. But for calendar sync specifically, Hetk is more efficient.
Who should choose Hetk
If your primary need is syncing Google, Outlook, and iCloud calendars, then Hetk is dramatically simpler, cheaper, and more reliable. You avoid manual Zap configuration, duplicate management, and the cost of multiple Zaps.
If you need to integrate calendars with other tools (Slack notifications, CRM updates, etc.), you might use Zapier in addition to Hetk. But for calendar-to-calendar sync, Hetk is the cleaner solution.

Cost comparison for calendar sync:
- Hetk Professional: $50/year (real-time sync, unlimited calendars, up to 8 sync pairs)
- Zapier Professional: from $239.88/year (750 tasks/month, requires custom Zap setup; two-way sync needs a separate Zap for each direction)

- Hetk: $15/year (Personal, includes all directions)
- Zapier: from $239.88/year (Professional; requires 2+ Zaps)
Zapier is 16x more expensive for the same task.
Feature-by-feature analysis
Zapier and Hetk both interact with calendars, but they operate at completely different levels of abstraction. Zapier is a general-purpose automation platform; Hetk is a specialized sync engine.
When you use Zapier for calendar sync, you’re building a workaround. You create a Zap that says “if event created in Google Calendar, create event in Outlook.” That’s one direction. For bi-directional sync, you need a second Zap. For three calendars all syncing to each other, you need 6 Zaps. Each Zap uses up your monthly Zapier quota and increases failure points.
Hetk handles bi-directional sync natively. You pick two-way once, and it syncs both directions automatically, handling duplicates and privacy controls without further configuration. It’s purpose-built for this one task.
Zapier’s strength is flexibility, you can connect calendars to Slack, email, CRM systems, payment processors, and dozens of other tools. If your use case is “when an event is created, send a Slack notification and create a CRM record,” Zapier is the right tool. But if your use case is “keep my calendars in sync,” Zapier is overkill and expensive.
Zapier’s free tier is 100 tasks a month, and every synced event change uses at least one task. A busy calendar can use that up well before the month ends.
Real-world comparison: complex sync scenario
Scenario: Freelancer with 3 calendars (personal Google, client Outlook, another client iCloud), needing bi-directional sync.
With Hetk:
- 1 sync relationship: Personal Google ↔ Client Outlook (bi-directional)
- 1 sync relationship: Personal Google ↔ Client iCloud (bi-directional)
- Real-time sync, automatic duplicate detection, privacy controls
- Cost: $15/year (Personal)
- Setup time: 5 minutes
With Zapier:
- Zap 1: Google → Outlook (one direction)
- Zap 2: Outlook → Google (reverse direction)
- Client iCloud: not possible, because Zapier doesn’t integrate with iCloud
- No automatic duplicate detection (you manage it manually)
- Limited privacy controls
- Cost: from $239.88/year (Professional)
- Setup time: 30-45 minutes (plus testing and troubleshooting)
Hetk is simpler, cheaper, and more reliable for this use case.
When Zapier actually makes sense for calendars
Use Zapier for calendar integration if:
- You need to connect calendars to non-calendar systems (Slack, Salesforce, email)
- You’re already a Zapier power user with existing workflows
- Your use case is notification/trigger-based, not sync-based
Use Hetk if:
- You need calendar-to-calendar sync
- You want bi-directional sync without manual configuration
- You care about cost and simplicity
FAQ
Can I use Zapier and Hetk together?
Yes. Hetk syncs your calendars; Zapier can then send notifications or trigger other workflows based on those events. This is actually a good workflow if you need both sync and external integrations.
Why can’t I just use Zapier for calendar sync?
You can, but you’d need multiple Zaps for bi-directional sync, Zapier doesn’t detect duplicates, setup is complex, and costs add up (from $239.88/year on Zapier Professional vs. Hetk’s $50/year). Hetk is purpose-built for this use case.
Does Zapier’s free tier work for calendar sync?
Yes, with limits: 100 tasks per month, and no bi-directional sync without multiple Zaps.
How many Zaps do I need for 3-way sync?
For full bi-directional sync between 3 calendars, you need 6 Zaps (each pair, both directions). For 4 calendars, you need 12 Zaps. This complexity is why Hetk’s single “sync” relationship model is so much simpler.
Does Zapier have duplicate detection like Hetk?
No. Zapier doesn’t detect duplicates automatically. If the same event syncs twice, you have to manually identify and delete the duplicate. Hetk prevents duplicates automatically.
Can Zapier send calendar events to Slack like Hetk can?
Hetk doesn’t send to Slack, it syncs calendars. Zapier can send to Slack. If you need calendar sync plus notifications, use Hetk + Zapier together.
What if I need calendar sync plus other integrations?
Use Hetk for sync ($50/year), then use Zapier (or a lighter tool like IFTTT) for notifications or external integrations. You pay for both (Hetk at $50/year, Zapier Professional from $29.99/month), and each tool does what it does best.
