Introduction

pywinauto is a set of Python modules to automate the Microsoft Windows GUI. At its simplest it sends mouse and keyboard actions to windows, dialogs and controls, and it can also read text and state from them.

It supports two backends: the Win32 API (backend="win32", the default) and Microsoft UI Automation (backend="uia") for WPF, Store apps and modern controls. The README notes that the mouse and keyboard input modules also work on Linux.

Scripts start or connect to an application, then reach windows and controls by title or attributes with a forgiving attribute-style syntax, such as app.UntitledNotepad.Edit.type_keys(...). The README describes it as a hobby project maintained in contributors’ spare time.

In the quality loop it supports desktop end-to-end checks and RPA-style automation in Python.

The source code is at pywinauto/pywinauto on GitHub under the BSD-3-Clause licence, with about 6,400 stars; the most recent commit was on 8 November 2026.
