Python’s versatility extends to GUI development, making it a strong choice for building desktop applications. However, selecting the right GUI framework can be overwhelming for developers who want a balance of simplicity, power, and cross-platform support. This article takes a closer look at the best Python GUI frameworks from a developer's perspective, focusing on practical use cases, learning experiences, and lesser-known tips.
1. Tkinter:
Tkinter, Python's built-in GUI framework, is often a first step into GUI development. It’s a lightweight library with basic components like buttons, labels, and input fields, which makes it ideal for small applications or learning the basics.
Despite its simplicity, Tkinter is highly adaptable, you can integrate custom widgets, embed web views, or even connect it with more complex libraries like OpenCV (for image processing) or Matplotlib (for plotting graphs). It’s not just a beginner's tool it has the depth to power medium-scale applications when used creatively.
If you’re familiar with HTML/CSS for web development, think of Tkinter as the “HTML of desktop apps” easy to learn but powerful when combined with additional tools and libraries.
Best For: Quick prototypes, small desktop apps, educational tools.
Advanced Use: Combine with PIL (Python Imaging Library) to create apps that handle images or Tkinter canvas for dynamic graphics.
2. PyQt5
Developer-Friendly Features: PyQt5 is not just about GUI development it’s a fully-fledged framework for building desktop software. One of the major advantages for developers is Qt Designer, a visual interface where you can drag and drop widgets and layouts without writing code. But what’s less often mentioned is how PyQt5 allows seamless integration with non-GUI components like databases, threading, and networking.
PyQt5 gives you modular control, which means you can scale your application in stages—building a basic interface first and layering on complex features like database connections or multi-threading without having to switch frameworks.
PyQt5’s flexibility makes it perfect for large, data-driven applications. For example, if you’re building a financial app or a dashboard that pulls real-time data from various APIs, PyQt5 will let you handle complex background operations smoothly while maintaining a responsive UI.
Best For: Commercial apps, cross-platform development.
Advanced Use: Pair it with SQLAlchemy for database-driven applications or with OpenGL for 3D graphics rendering.
3. Kivy
The Game Changer: Kivy is often introduced as a mobile-first framework, but it’s much more than that. It’s ideal for modern applications where the user experience is defined by multi-touch gestures and responsive layouts. If you're developing for touchscreen devices, Kivy is in its element, and its open-source nature allows for full customization.
A standout feature of Kivy is its declarative language, called Kv. This syntax is similar to CSS for web development but designed for GUIs, which allows you to define UI components and their behaviors in a readable way. The separation of UI logic (Kv) and Python code makes Kivy applications easier to maintain and scale.
If you want to create mobile apps that run on both Android and iOS but don’t want to learn multiple languages (Java/Kotlin, Swift), Kivy is a great alternative. Plus, with tools like Buildozer, you can compile Python code into mobile executables without needing separate codebases.
Best For: Mobile apps, touch interfaces, multimedia projects.
Advanced Use: Combine with Pygame for game development or implement gesture-based apps for interactive exhibits.
4. wxPython
Unlike other frameworks that prioritize cross-platform compatibility over native design, wxPython ensures that your app looks and feels native on every platform (Windows, macOS, and Linux). This means that users get the same interface consistency as they would with apps built in platform-specific languages.
wxPython’s focus on native components (like buttons and dialog boxes) means you don’t have to sacrifice user experience for cross-platform capability. It also offers a rich set of tools for customization. Lesser known but extremely powerful, wxPython lets you manage platform-specific features with conditional coding, so you can still fine-tune behaviors for each operating system.
Use wxPython if your target audience is on multiple desktop platforms, but you don’t want to worry about re-designing UI elements for each OS.
Best For: Desktop apps with a native look.
Advanced Use: Use it to create custom applications for enterprise clients who need a consistent experience across platforms.
5. PySide2: The LGPL Alternative to PyQt5
PySide2 (or Qt for Python) is the open-source alternative to PyQt5. It provides the same extensive features as PyQt5 but comes with a licensing model that’s more favorable for commercial applications, especially if you want to avoid the licensing fees associated with PyQt.
While PySide2 mirrors PyQt5 in almost every way, it comes with a unique advantage for developers building commercial projects without the need for paid licenses. The Qt for Python team is actively working on adding more features and improving the framework, making it a solid long-term investment for developers.
If you’re familiar with PyQt5, you can switch to PySide2 without much hassle since the two share nearly identical APIs. It’s an easy way to continue working on commercial projects without worrying about costs.
Best For: Commercial desktop applications with licensing freedom.
Advanced Use: Leverage it for multimedia apps, integrating features like video streaming or graphical animations.
6. Dear PyGui
Dear PyGui is not your traditional Python GUI framework.
