refer first to this doc (section Externally Visible Server) on how to expose your local Flask app to make it accessible from trusted devices in your network for testing purposes.

$(venv) flask run --host=0.0.0.0

or in your app.py

from flask import Flask
[..]
app = Flask(__name__)
[..]
if __name__ == "__main__":
   app.run(host="0.0.0.0", port=5000, debug=True)

and then :

$(venv) python app.py

but if it happens and you got this error dial tcp 0.0.0.0:5000: connect: connection refused then try to use the local ip address (192.168.x.y instead of 0.0.0.0) of the machine hosting your Flask app. you may find this thread usefull

You can access your server on devices in the same Network / Wifi with your private IP address and the port. On Mac OS option + click on Wifi in your Taskbar.

On linux: > ifconfig

  • Instead of localhost (127.0.0.1), you need to type your router's public IP. If you do not already know it, you can retrieve it by typing ipconfig (for Windows) or ifconfig (for Linux) in the command line.
  • You also need to disable your firewall or add an inbound rule for the port used by your server (e.g. 5000).
