WebDriverAgent GitHub license Build Status Carthage compatible

WebDriverAgent is a WebDriver server implementation for iOS that can be used to remote control iOS devices. It allows you to launch & kill applications, tap & scroll views or confirm view presence on a screen. This makes it a perfect tool for application end-to-end testing or general purpose device automation. It works by linking XCTest.framework and calling Apple's API to execute commands directly on a device. WebDriverAgent is developed and used at Facebook for end-to-end testing and is successfully adopted by Appium.


  • Works with device & simulator
  • Implements most of WebDriver Spec
  • Implements part of Mobile JSON Wire Protocol Spec
  • USB support for devices
  • Inspector endpoint with friendly user interface to inspect current device state
  • Easy development cycle as it can be launched & debugged directly via Xcode
