ngrok is a fantastic tool, that I use on an everyday basis when building solutions cloud. It allows me to host and debug an application locally and at the same time host the website or API’s with a publicly accessible https endpoint. As I work quite a bit with Microsoft Teams development this is essential when building bots (Azure Bot Service cannot talk to localhost) or building out Teams Tabs with SSO. However, how good this tool might be, there are several firewalls, security clients and companies that actively block ngrok. Ngrok does establish a tunnel from the public internet to your machine, and you should be aware of that - it is a security risk. Most notably ngrok has been used as tools for malicious attacks.
