Create desktop applications with Flask (or Django)!

Project description

Create desktop applications with Flask/Django!



pip install flaskwebgui

Or download source file and place it where you need.

Usage with Flask

Add bellow js code to your base.html (or to your script.js file)


document.addEventListener('DOMContentLoaded', function() {

    var url = ''; 
    fetch(url, { mode: 'no-cors'});
    setInterval(function(){ fetch(url, { mode: 'no-cors'});}, 5000)();



In your main python file add bellow 3 lines of code

from flask import Flask
from flaskwebgui import FlaskUI #get the FlaskUI class

app = Flask(__name__)

# Feed it the flask app instance 
ui = FlaskUI(app)

# do your logic as usual in Flask
def index():
  return "It works!"

# call the 'run' method

Usage with Django

Make a file ''(file name not important) next to '' file in the django project folder.

Add the js code like we did it up.

Inside '' file add these 2 lines of code:

from flaskwebgui import FlaskUI #import FlaskUI class

#You can also call the run function on FlaskUI class instantiation


Next run from your terminal the bellow command:



Default FlaskUI class parameters:

  • app, ==> flask class instance

  • width=800 ==> default width 800

  • height=600 ==> default height 600

  • fullscreen=False ==> start app in fullscreen

  • maximized=False ==> start app in maximized window

  • app_mode=True ==> by default it will start chrome in app(desktop) mode without address bar

  • browser_path="" ==> path to browser.exe (absolute path to chrome C:/browser_folder/chrome.exe)

  • server="flask" ==> the default backend framework is flask (django is suported also), you can add a function which starts the desired server for your choosed framework (bottle, web2py pyramid etc)

  • port=5000 ==> specify other if needed, make sure to add port+1 in the js script

  • socketio=SocketIO Instance ==> Flask SocketIO instance (if specified, uses instead of for Flask application)

Should work on windows/linux/mac with no isssues.

Develop your app as you would normally do, add flaskwebgui at the end or for tests. flaskwebgui doesn't interfere with your way of doing a flask application it just helps converting it into a desktop app more easily with pyinstaller or pyvan.


You can distribute it as a standalone desktop app with pyinstaller or pyvan.


It's a combination of and

flaskwebgui just uses threading to start a flask server and the browser in app mode (for chrome). It has some advantages over flask-desktop because it doesn't use PyQt5, so you won't have any issues regarding licensing and over Eel because you don't need to learn any logic other than Flask/Django.

Submit any questions/issues you have! Fell free to fork it and improve it!
