Tkinter features and specs

  • Built-in Standard Library
    Tkinter comes bundled with Python, so there is no need for additional installations. This makes it highly accessible and quick to set up for projects.
  • Ease of Use
    Tkinter provides a simple syntax and an easy-to-understand system for building GUI applications, making it ideal for beginners who are just starting with programming.
  • Cross-Platform Compatibility
    Tkinter applications can run on multiple operating systems like Windows, macOS, and Linux without modification, which ensures broader audience reach.
  • Strong Community Support
    Being part of Python's standard library means that Tkinter benefits from Python's extensive community support, with plenty of tutorials and resources available online.
  • Object-Oriented Approach
    Tkinter supports an object-oriented programming model, which allows for structuring code in a manageable way, especially for larger applications.

Possible disadvantages of Tkinter

  • Limited Widget Set
    Compared to more modern GUI frameworks, Tkinter has a limited set of widgets and may not support advanced user interface features that newer applications might require.
  • Outdated Look and Feel
    The default Tkinter themes and styles may look outdated by modern standards, which might not be suitable for applications where a contemporary design is important.
  • Performance Limitations
    Tkinter may not perform well with applications requiring high-performance graphics or real-time updates, as it is not optimized for these tasks.
  • Learning Curve for Complex Applications
    While simple to use for basic applications, building more complex UI components can become challenging and might require a deeper understanding of the Tkinter framework.
  • Lack of Advanced Features
    Some advanced features like drag-and-drop, custom widgets, or native look and feel on different platforms might be either missing or require additional work to implement.

Flet features and specs

  • Ease of Use
    Flet provides a straightforward API that simplifies the process of building interactive web applications, making it accessible even to those with minimal web development experience.
  • Cross-Platform Support
    Flet supports multiple platforms, allowing developers to create applications that can run seamlessly across different devices and operating systems.
  • Rapid Development
    With a focus on fast development cycles, Flet enables developers to quickly prototype and deploy applications, significantly reducing time to market.
  • Rich UI Components
    Flet offers a wide range of built-in UI components that help developers create visually appealing and functional interfaces without having to start from scratch.
  • Community and Documentation
    Flet comes with comprehensive documentation and an active community, providing valuable resources and support for developers throughout the development process.

Possible disadvantages of Flet

  • Limited Customization
    While Flet offers many built-in components, the level of customization available may not satisfy developers looking for highly tailored UI experiences.
  • Dependency on Flet Ecosystem
    Developers are tied into the Flet ecosystem, which could pose challenges if they need to integrate with other tools or want to migrate away in the future.
  • Performance Concerns
    As with many high-level frameworks, there might be performance overheads, especially for resource-intensive applications.
  • Learning Curve
    Although designed for ease of use, developers familiar with other web development frameworks may need time to learn and adapt to Flet's unique features and paradigms.
  • Emerging Technology
    Being a relatively new technology, Flet might still be undergoing changes, which may lead to stability issues or lack of long-term support.

25 Python Frameworks to Master
It’s a great option for creating simple and easy-to-use graphical user interfaces in Python and allows you to add a GUI to your already working scripts pretty easily. PySimpleGUI wraps the power of 4 different GUI libraries, PySide, Tkinter, wxPython, and Remi.

Which Python GUI library should you use? Comparing the Python GUI libraries available in 2023
Tkinter is a simple library with support for standard layouts and widgets, as well as more complex widgets such as tabbed views & progressbars. Tkinter is a pure GUI library, not a framework. There is no built-in support for GUIs driven from data sources, databases, or for displaying or manipulating multimedia or hardware. However, if you need to make something simple that...
10 Best Python Libraries for GUI
Another top Python library for GUI is Tkinter, which is an open-source Python Graphic User Interface library. It is well known for its simplicity and comes pre-installed in Python, meaning there is no work on your part. These features make it a great choice for beginners and intermediates, but it is not capable of carrying out larger-scale projects.

Top 10 Python GUI Frameworks for Developers
Often referred to as the go-to GUI toolkit by a majority of Python developers, Tkinter was created to equip modern developers with a standard interface to the Tk GUI toolkit with its Python bindings. In Tkinter’s world, most of the visual elements that we’re familiar with are called widgets, and each of these widgets offers a different level of customizability.

  • The Adventures of Blink S2e7: A GUI Screen in Python
    For our hangman, I've elected to use Tkinter. It has a pre-built collection of little widgets that make dialog-based apps work, and I think it will be useful for Hangman, which doesn't require a great deal of animation and image management but does require us to have an easy-to-use interface for the user to make changes. - Source: dev.to / 8 months ago
  • Ask HN: How popular is Tcl in 2024?
    >> So it's hard for me to recommend tk for GUI development. Tcl/Tk is widely used in lightweight legacy GUIs. Python distributions will typically include tkinter (https://docs.python.org/3/library/tkinter.html) which is just a Python wrapper for Tk.

  • Using Uv and PEP 723 for Self-Contained Python Scripts
    It's more the latter, particularly when Rust is used in libraries (eg. FastAPI) as opposed to tools, as it's destroying portability. For example I use flet[0] in some of my projects, and I have to be increasingly careful about the other dependencies as there is no support for the Rust toolchain within Dart/Flutter, and even if there was it still sounds like it'd be a nightmare to maintain.
