winget install --id=mjishnu.raven -e An open-source client to search, download, install, and update Microsoft Store apps without MS Store services.
A free, open-source alternative Microsoft Store client for Windows
Raven is a modern, native Windows application that serves as a fully-featured alternative to the Microsoft Store. It can do everything the official store does — search, download, install, and update apps — while also adding powerful capabilities like sideloading external UWP/MSIX packages, exporting Store apps for offline use, and bandwidth-saving delta downloads.
Built with WinUI 3 and .NET 10, Raven delivers a clean, fluent UI that feels right at home on Windows 10 and 11.
