Best CalendarBridge Alternatives in 2026
A fair comparison of the best CalendarBridge alternatives for syncing Google, Outlook, and iCloud calendars.
CalendarBridge is one of the longer-running calendar sync services, and it does the job well for many people. Common reasons to look elsewhere are cost as your calendar count grows, wanting a free plan instead of a trial, or wanting a different set of features.
About this comparison: AllMyMeetings publishes this page and is one of the alternatives listed, so we're not neutral. Every competitor fact below comes from that company's own website, with links, and we've left out claims we couldn't verify. Prices and features as of October 2026. Check each vendor's pricing page before you switch.
TL;DR: If you want to stop paying for basic sync, AllMyMeetings has a permanent free plan (one one-way Free/Busy sync), supports iCloud, and includes an MCP server for AI assistants on every plan. OneCal is a strong paid alternative with multi-way sync. If you need a HIPAA BAA, staying on CalendarBridge is probably the right call.

Why people look for CalendarBridge alternatives
Cost as calendars add up
CalendarBridge prices by calendar count. Two calendars cost $4/month on annual billing; going past five calendars means the $32/month Pro plan.
No free plan
If you only need personal events to block time on your work calendar, paying every month for it can feel like too much. A few alternatives cover that case for free.
Pairwise connections
CalendarBridge connects calendars in pairs. Some people prefer a tool that syncs several calendars in one group.

AllMyMeetings syncs Google Calendar, Outlook / Microsoft 365, iCloud, and read-only ICS feeds.
Where AllMyMeetings differs from CalendarBridge:
- Free plan, not a trial: 2 calendar accounts, 1 one-way sync in Free/Busy mode, and 1 scheduling page, with no expiry
- MCP server on every plan, including free: Claude and ChatGPT connectors sign in with OAuth, no token needed. Setup guide.
- Priced by account, not by calendar: Pro ($5/month or $50/year) covers 4 calendar accounts and 6 syncs with two-way sync
- Direct ICS feed subscriptions
- Three privacy modes: Full details, Free/Busy, and Private. Attendees are never copied.
Where CalendarBridge is stronger:

AllMyMeetings pricing: Free; Pro $5/month or $50/year; Business $15/month or $150/year (unlimited accounts, syncs and scheduling pages). Pro is free for 14 days from when you connect your first calendar, no card needed. Two-way sync and Full details need a paid plan.
Best for: Individuals and small teams who want to start free, use iCloud, or connect an AI assistant.
2. OneCal: best for multi-way sync
OneCal syncs Google, Outlook, and iCloud and lets you sync several calendars together in one setup.
Where OneCal differs from CalendarBridge:
- Multi-way sync groups
- Unlimited one-on-one and collective scheduling links on every plan
- Its own calendar MCP server using OAuth
- Up to 50 calendars on Premium
Limitations:
- No free plan; 14-day trial
- ICS calendars must be added to a Google or Microsoft account first and only work as one-way sources (OneCal docs)
OneCal pricing: Starter $5 (2 calendars), Essential $10 (5), Premium $25 (50) per user per month, billed annually. Source.
Best for: Paying users with many calendars who want multi-way sync.
3. SyncGene (moving to CiraHub): for contact sync too
SyncGene syncs calendars and contacts across Google, iCloud, and Outlook. Its pricing page says SyncGene is moving to CiraHub, where new subscriptions start.

4. Reclaim.ai: for AI time blocking

Where it differs: AI time blocking, a free Lite plan (1 calendar sync, 1 scheduling link), and task integrations.

5. OGCS (Outlook Google Calendar Sync): free desktop option

You want two-way sync for 3-4 accounts at a low price: AllMyMeetings Pro ($50/year) covers 4 accounts and 6 syncs. Compare that with CalendarBridge Premium ($96/year for 5 calendars) based on how many calendars you actually need.
You need a HIPAA BAA: Stay with CalendarBridge.
You want multi-way sync groups: OneCal.
You need more than calendar sync: SyncGene / CiraHub for contacts, or Reclaim.ai for AI time management.
