WinAppDriver Review 2026

WinAppDriver enables automated testing of Windows applications with ease. Boost productivity using this reliable automation framework.

WinAppDriver (Windows Application Driver) is a free, open-source UI test automation framework developed by Microsoft that supports Selenium-like testing of Windows desktop applications, with pricing at $0 since it is fully free to use. It is designed for QA engineers, SDETs, and developers building automated regression suites for Windows 10 and Windows 11 applications including UWP, WPF, WinForms, and classic Win32 apps.

First released by Microsoft in 2016 and hosted on GitHub under the microsoft/WinAppDriver repository, the tool implements the W3C WebDriver protocol (JSON Wire Protocol) so teams can reuse existing Selenium bindings in Java, C#, Python, Ruby, and JavaScript. It runs as a standalone service on port 4723 by default and hooks into the Windows UI Automation framework to locate elements by AutomationId, ClassName, Name, XPath, and accessibility identifiers. WinAppDriver integrates natively with Appium, allowing teams to run Windows, iOS, and Android tests through a single driver interface, and it ships with a companion tool called WinAppDriver UI Recorder that generates XPath selectors and C# code snippets by recording user interactions. Based on our analysis of 870+ AI tools in the directory, WinAppDriver stands out as one of the few first-party Microsoft-maintained desktop automation tools that is completely free.
