Watt Toolkit (formerly called Steam++) is an open-source, cross-platform toolkit for Steam users, primarily aimed at players in China who face network restrictions that make accessing Steam's community pages and features unreliable. The main feature is a local reverse proxy, a tool that intercepts your device's network traffic and reroutes it so that Steam's community website and services become accessible without the usual connectivity problems common in mainland China. Beyond network access, the toolkit includes several other practical features: a quick account switcher that lets you jump between multiple Steam accounts already saved on the device without re-entering passwords; a Steam achievement manager that lets you view and edit game achievements; and a local two-factor authenticator, which generates the same login codes that the Steam mobile app would generate, so you can approve logins and marketplace transactions from your desktop without your phone. There is also a tool to force games to run without a window border frame. The app is built using C# and .NET, with AvaloniaUI for the desktop interface (a cross-platform UI framework), making it run on Windows, Linux, macOS, and Android. You would use Watt Toolkit if you are a Steam gamer, especially in China, who wants smoother access to Steam community features and a set of handy account management utilities in one place.
