◆ run()

searx.webapp.run ( )

Runs the application on a local development server.

This run method is only called when SearXNG is started via ``__main__``::

Do not use :ref:`run() <flask.Flask.run>` in a production setting.  It is
not intended to meet security and performance requirements for a production
server.

It is not recommended to use this function for development with automatic
reloading as this is badly supported.  Instead you should be using the flask
command line script’s run support::
