Oncall is the on-call management and scheduling system at LinkedIn.

It offers highly customizable scheduling for on-call shifts, as well as a streamlined UI for editing, swapping, and overriding on-call shifts.

REST API built for easy integration

  • Oncall sports a fully-documented API easily targeted by third-party applications to schedule and modify on-call shifts.

Native support for follow-the-sun shifts

  • Sharing on-call shifts across time zones? Built-in support for interleaving 12-hour events make split day/night on-call shifts easy to create and manage.

Clean, intuitive interface

  • Oncall’s click-and-drag calendar makes creating and editing events easy, and its SPA design is both smooth and performant.
