Top 5 CalendarBridge Alternatives [Differences + Similarities]

Published on

If you manage more than one calendar, keeping track of what's happening in each one can be tough. People in each group only see some of the schedules, so sometimes they might book the same time slot by mistake.

To avoid this, tools like CalendarBridge synchronize the calendars, so the events are replicated in all your calendars. If someone books a meeting in any of the calendars you manage, you can be confident that you won’t be double booked.

In this article, we’ll explore the top 5 CalendarBridge alternatives, showcasing the similarities, differences, and pricing of each CalendarBridge alternative.

Why do Users Look for Alternatives to CalendarBridge?

  • Only one-way sync support: With CalendarBridge you can sync one calendar to another at a time, in one direction. If you want to synchronize 3 calendars, you have to create 6 configurations. The number of sync configurations increases with the calendars you want to sync. Even though this is modular, other solutions allow you to sync multiple calendars in one config, in less than one minute.
  • Calendar Sync speed and reliability: Since CalendarBridge and other calendar sync tools rely on Outlook and Google Calendar API, things don’t always go smoothly. Depending on how many events your calendars have, a calendar sync may take more than 15 minutes to finish.
  • Per Calendar Sync Pricing: CalendarBridge charges per Calendar Sync Configuration. As mentioned, the calendar sync configurations are one-way, so to keep 3 calendars in sync, you need 6 calendar sync configurations. This leads to more work to sync multiple calendars and more sync configurations. Furthermore, the price increases the more sync configurations you create.
  • Better UI and UX: UI and UX are subjective, so users might seek more modern UI and better-crafted UX.
