PySide6-Fluent-Widgets

What it is and what it does

PySide6-Fluent-Widgets is a widget library that brings Microsoft's Fluent Design System to PySide6 applications. It wraps PySide6 with pre-built, styled components that follow Windows design guidelines, so you can build modern desktop UIs without hand-coding every visual detail. The library depends on PySide6 for the underlying Qt bindings, PySideSix-Frameless-Window for custom window chrome, and darkdetect to adapt the UI to system light/dark mode.

The package is distributed in two variants: a standard version and a full-featured version (installable with [full]) that includes additional components like AcrylicLabel. It's actively maintained with 90409 monthly downloads and comprehensive documentation. Non-commercial use is free under GPLv3, but commercial applications require a paid license.

Use it for:

• Build a desktop application with a modern Windows Fluent Design look without manually styling every control.
• Create a cross-platform tool that adapts its UI theme to the system's light or dark mode preference.
• Develop an internal utility or data-entry application that needs professional appearance with minimal design effort.
• Prototype a Windows-native UI quickly using fluent components in Qt Designer.

Verify before relying

• Whether the full-featured version with AcrylicLabel requires additional system dependencies or compilation steps.
• Exact Python version compatibility (requires_python is unspecified in the fact sheet).
• Performance characteristics or memory footprint when rendering large numbers of fluent widgets.
