Online Tkinter Editor

Build a desktop-style Python app and use it right beside your code. Your tkinter windows appear in the output pane, where you can click, type and drag as you would on a computer. Buttons, entries, menus, canvases, dialogs and ttk widgets are all here, and examples such as a calculator and a to-do list show how the pieces fit together.

How to run Tkinter code online

  1. This page opens with Tkinter selected, so you can start typing straight away.
  2. Write your code in the editor, or open files from your computer: single files, or a whole project as a .zip.
  3. Press Run, or Ctrl+Enter. The output appears in the panel beside the editor, and when the program asks for input you type it there and press Enter.
  4. Share a copy with a link, or save your files to your computer.

Python tkinter on Online IDE

  • Write import tkinter as usual: Tk, Toplevel, pack, grid, place, bind() and after() are all available.
  • Windows are drawn to look like tkinter on Windows 10 and 11, whichever theme this site is in.
  • messagebox, simpledialog and colorchooser open inside the window. File dialogs open and save in the program's folder, beside your tabs.
  • print() goes to the output panel under the window.

Example: a button that counts clicks

import tkinter as tk

root = tk.Tk()
root.title("Counter")
clicks = tk.IntVar(value=0)

tk.Label(root, textvariable=clicks, font=("Segoe UI", 24)).pack(padx=40, pady=12)
tk.Button(root, text="Click me", command=lambda: clicks.set(clicks.get() + 1)).pack(pady=12)

root.mainloop()

Frequently asked questions

Do I need Python on my computer?

No. Python runs in your browser tab through Pyodide, and your window opens next to your code. It works on Windows, macOS, Linux and Chromebooks.

Is this real tkinter?

A browser has no Tk, so import tkinter gets a version built for it, with the same classes, options and methods. A program you write here also runs on your computer.

Will my app look the same on my computer?

On Windows, very nearly: fonts, sizes, colours and the ttk theme are drawn to match Windows 10 and 11. On other systems it follows that system's own look.

Do dialogs work?

Yes. messagebox and simpledialog open inside the window and return the answer, as they do on a desktop. File dialogs use the program's folder, where your other tabs are.

What is missing?

Tcl itself, so tk.call() and eval() do very little, along with embedding other programs' windows and tray icons. Text tags change colours and underlining but not fonts, and PhotoImage reads PNG and GIF only.
