Nylas Alternative
What does OneCal Unified Calendar API offer as a Nylas alternative?
Integrate Google Calendar, Outlook, and iCloud using one API
The OneCal Unified Calendar API makes it easy for your application to support all major calendar providers without the hassle of spending extra time to learn each API or maintain multiple integrations.
Battle-tested by the OneCal Calendar Platform
The OneCal Unified Calendar API is used across all our features, like Calendar Sync, Scheduling Link, and Calendar View. Our Calendar Sync alone has synchronized close to 1 Billion of calendar events between Outlook, iCloud, and Google Calendar. Thousands of users across different industries use our Scheduling Links as their default scheduling solution.
Not scheduling specific
Our Unified Calendar API is not specific to building a scheduling app; you can use it to create a calendar app, a scheduling platform, sync tasks to calendars, and much more.
Reasonable Pricing
Although we haven't finalized our pricing, we can assure you that it will be highly competitive. We've spoken to dozens of customers and gathered feedback regarding the pain points and how they intend to use our Unified Calendar API.
Support for Webhooks
Apps that interact with calendars often need to know when changes happen to calendars. Using our Unified Calendar API product, you can register your own webhooks and get notified when changes happen to calendars. No need to periodically poll for changes or implement custom solution for each calendar provider. The whole webhook infrastructure is implemented and managed by us, you only need to worry about responding to the changes we send you.
