Python GUI Builder for Python Developers

What is pyuibuilder the Python GUI Designer?

Designing user interfaces in Python often means writing lines of geometry management code using `pack()`, `grid()`, or `place()` and styling the app without knowing how the end result would look like. This slows down development, especially for developers who want quick prototyping. pyuibuilder solves this by providing a visual drag-and-drop designer that automatically generates clean, Pythonic code you can export and run anywhere.

Powerful Features for Python GUI Developers

• Web and dekstop app: With PyUiBuilder you can build either on our convenient web app or use our desktop app.
• Drag-and-Drop Interface: Place widgets on a canvas just like in Figma or Qt Designer.
• Live Preview: See how your UI looks and behaves before exporting.
• Code Export: Get production-ready Python code compatible with Tkinter, customtk, and more.
• Multi-framework Support: Choose between Tkinter, CustomTkinter, PySide (upcoming), and others.
• 3rd party UI widget Support: Add your favourite 3rd party widgets like Timepicker, video player, maps and more
• Widget Inspector: Edit widget properties, layout, and events in a property panel.
• Event Binding: Add click handlers and callbacks visually, then edit logic in your IDE.
• Responsive Layouts: Easily design UIs that adapt to different window sizes.
• Dark Mode: Optional interface mode for night coding sessions.
• Code editor: PyUiBuilder comes with an inbuilt code editor making it easier to write code and add event handlers.

How PyUIBuilder works?

pyuibuilder provides a visual design canvas where you can drag widgets like buttons, labels, inputs, and containers onto your UI. Each element can be resized and moved. You can also bind events like button clicks to Python functions.

Once your design is ready, click "Export" to generate clean Python code with layout logic, widget creation, and event bindings, all done for you.

Generated Code Example by Tkinter GUI builder

Here's a basic example of what pyuibuilder exports when you create a simple window with a button:

# This code is generated by PyUIbuilder: https://pyuibuilder.com

import tkinter as tk
from tktimepicker import AnalogPicker, AnalogThemes, constants
import tkintermapview

def click_handler(event):
  pass

main = tk.Tk()
main.config(bg="#332f2f")
main.title("Main Window")

timepicker = AnalogPicker(parent=main, type=constants.HOURS12)
timepicker_theme = AnalogThemes(timepicker)
timepicker_theme.setNavyBlue()
timepicker.place(x=80, y=145, width=250, height=350)

map_viewer = tkintermapview.TkinterMapView(master=main)
map_viewer.place(x=423, y=181, width=400, height=250)

label = tk.Label(master=main, text="Sample text")
label.config(bg="#E4E2E2", fg="#000")
label.place(x=83, y=69, width=130, height=46)

button = tk.Button(master=main, text="Click me")
button.config(bg="#65ff4a", fg="#0b0909")
button.place(x=457, y=108, width=80, height=40)


main.mainloop() 
  

Output

This is the design for tkinter

This is just one of many export options. You can also target CustomTkinter, or pyside (upcoming) and even web-based frameworks like Flet in future releases.

Supported Frameworks

pyuibuilder is framework-agnostic. You can switch between popular Python GUI libraries in the same project. Currently supported:

• Tkinter - Lightweight and built into Python
• CustomTkinter - Modern-looking components
• PySide - Professional-grade UIs (coming soon)
• Kivy (coming soon)
• Flet (coming soon)

Built With Developers in Mind

We understand developers want readable, modular, and editable code. That's why pyuibuilder focuses on generating clean and extensible Python files. We follow PEP-8 and let you control structure.

Use Cases

• Startups – Rapidly prototype MVPs and tools
• Students – Build Python GUI apps without fighting layout managers
• Freelancers – Deliver GUIs quickly for clients
• Educators – Use it to teach GUI concepts visually

What Developers Say

“PyUIBuilder made Python GUI development so much easier for me. The drag-and-drop feature and clean code output saved a lot of time. Highly recommend it to anyone building Python interfaces!”

“I like that this visual design generates clean code!.”
