Ngrok is a popular reverse proxy tool that allows users to create secure tunnels from a public endpoint to a web service running locally. It enables users to expose a port on their local system to a public URL, redirecting external connections to their local host. Ngrok has several use cases, including sharing a website running on a private network with colleagues, creating a TCP server on a device, port forwarding, testing mobile apps connected to locally running backends, providing stable addresses for devices deployed in the field, and running personal cloud services from home. It can also be used in ethical hacking, allowing users to remotely take the reverse shell and reverse the connection of any device through TCP tunneling with Ngrok.
