FreeBusy API

Instantly show and manage availability right inside your app.

Richness of calendar data at your fingertips

FreeBusy connects to everyone's existing calendars. It matches availability using data from each calendar and makes smart suggestions for when to meet. FreeBusy works with all calendar systems, whether corporate, school, or personal.

Our goal is to make it easy for any developer to take advantage of this data and make their apps availability-aware. We offer both a low-level API to obtain raw calendar data and a structured high-level API to easily produce an availability view.
