A simpler, cheaper CalendarBridge alternative
CalendarBridge connects your Google and Microsoft accounts and syncs events between them — writing busy-blocks back into each calendar and adding scheduling pages and an AI assistant on top. It's a capable tool, but it's priced and built for that full sync-and-schedule workflow, starting around $4–5/mo for two accounts and climbing to $32–40/mo at the top tier.
If what you actually want is simpler — see all my calendars in one place — you don't need a two-way sync engine reaching into your accounts. iCal Merge reads each calendar's feed and publishes one combined, read-only link you can subscribe to anywhere. It works with any calendar that exposes an iCal/ICS URL, never writes to your accounts, and a useful plan is free — with Pro at $5/mo or $50/yr.

Where iCal Merge wins
- Price. One flat Pro plan at $5/mo (or $50/yr) covers 10 calendars and 25 sources — less than CalendarBridge's entry tier, and a fraction of its $32–40/mo top tier. Most people never need to pay at all.
- Works with any calendar. Anything with an iCal/ICS link — iCloud, Outlook, Notion, your kid's sports app, a league fixture list, a school feed. CalendarBridge is built around OAuth-connected Google and Microsoft accounts.
- Read-only by design. We never get write access to your calendars. We read each secret feed and publish a separate combined link — nothing iCal Merge does can alter, delete, or move an event in your real calendar.
- Nothing to install or connect. Paste a feed URL and you're done. No account linking, no browser extension, no busy-block clutter written into your calendars.
Where CalendarBridge does more
We'd rather be straight with you than oversell. CalendarBridge does real things iCal Merge deliberately doesn't:
- Two-way sync. CalendarBridge writes busy-blocks back into each connected calendar, so a meeting on your work calendar shows up as "busy" on your personal one and prevents scheduling conflicts at the source. iCal Merge produces one combined feed you subscribe to — it shows everything in a single view, but it doesn't write back into your other calendars.
- Scheduling pages. CalendarBridge includes Calendly-style booking pages. iCal Merge doesn't do scheduling.
- AI assistant & HIPAA BAA. Their higher tiers add an AI executive assistant and a HIPAA Business Associate Agreement for regulated use. iCal Merge offers neither.
The honest test: if your goal is to prevent double-bookings by syncing availability between accounts, CalendarBridge is built for that. If your goal is to see every calendar in one place — on your phone, in Apple Calendar, or on a wall display — that's exactly what iCal Merge does, for far less.
What the merged feed looks like
Every source keeps its own label, so a combined feed still tells you at a glance where each event came from — and a clash between two calendars is easy to spot in one view.
Which one should you pick?
- Pick iCal Merge if you want one combined, auto-updating feed to view or share, you have calendars beyond Google/Microsoft, you'd rather not give a tool write access to your accounts, or you just don't want to pay $30+/mo.
- Pick CalendarBridge if you specifically need two-way availability sync between connected accounts, built-in scheduling pages, or HIPAA coverage.
Frequently asked questions
Is iCal Merge a free CalendarBridge alternative?
iCal Merge has a genuinely free plan that merges one calendar with up to three sources into a single read-only feed. Pro is $5/mo or $50/yr for 10 calendars and 25 sources. CalendarBridge’s paid individual plans start around $4–5/mo and go up to $32–40/mo, so iCal Merge is substantially cheaper for the “see everything in one place” use case.
Does iCal Merge sync events between my calendars like CalendarBridge?
No. CalendarBridge does two-way sync — it writes busy-blocks back into each connected account to prevent conflicts. iCal Merge instead reads each calendar’s feed and publishes one combined, read-only link. You see every event in one place, but iCal Merge never writes to your real calendars. If true two-way availability sync is what you need, CalendarBridge is built for that.
Do I have to connect my Google or Microsoft account?
No. iCal Merge works from each calendar’s iCal/ICS feed URL — you paste the link rather than granting account access. That also means it works with calendars CalendarBridge doesn’t connect to, like iCloud, Notion, sports apps, and league fixture feeds.
Can iCal Merge stop me double-booking?
It puts every calendar in one view, so an overlap is easy to see at a glance — but it does not write availability back into your accounts the way CalendarBridge’s sync does. If preventing conflicts automatically at the source is the priority, that’s CalendarBridge’s strength.
Which should I choose?
Choose iCal Merge if you want one combined, auto-updating feed to view or share, you use calendars beyond Google and Microsoft, or you’d rather not give a tool write access to your accounts. Choose CalendarBridge if you specifically need two-way sync, built-in scheduling pages, or HIPAA coverage.
