About Magpie

Magpie is an open source window upscaler for Windows that scales application windows to a higher resolution using built-in scaling algorithms and filters. It supports both fullscreen and windowed scaling and works across multiple monitors. The project is distributed as a GitHub repository under the GPLv3 license.

It runs on Windows 10 version 1903 or later, or Windows 11, and requires DirectX feature level 11. Some older windows that do not support high DPI may need a compatibility setting changed before scaling looks correct. Pricing information is not listed in the source.
