Using ngrok with Flask

tip

This article assumes you have Python, PIP, and Flask already installed.

To share a local Flask development server with someone else, simply run: ngrok http 5000.

Note: For users on the latest MacOS, there is an issue where the default port of 5000 is used by Apple AirPlay Receiver. You can use a different port for your Flask app or see this Stack Overflow post for disabling the AirPlay Receiver service.

You can also use the ngrok Python SDK to start a tunnel to the Flask dev server via python code, or using a ngrok ASGI runner with an ASGI Wrapper.
