Really disable logger logging in Flask

flask.py

# I have my own logging setup and had a hard time disabling console output in Flask. 

    app.logger.disabled = True
    log = logging.getLogger('werkzeug')
    log.disabled = True
    
# New, 2022 Method:

    logging.getLogger('werkzeug').disabled = True

For the record, this only disables the logging statements. If you want to disable the console warnings too, you have to monkeypatch the function that does that (see: cs01/gdbgui#425):

import flask.cli    
flask.cli.show_server_banner = lambda *args: None

The old hack (os.environ["WERKZEUG_RUN_MAIN"] = "true") doesn't work in werkzeug >=2.1.0.

@mconigliaro Man! your code works well! Thanks :)

If using flask-socketio:

logging.getLogger("werkzeug").disabled = True
logging.getLogger("geventwebsocket.handler").disabled = True

Really nice! I'm using Flask 2.2.3, it works.

Thank you!
This worked perfectly for me.

app = Flask(name)
logging.getLogger('werkzeug').disabled = True
