in plain english

ngrok is a reverse proxy service that creates a secure public URL that tunnels traffic to a server running on your local machine. In everyday terms: if you are building a website on your own computer and want to show it to someone else, or test it with an external service like a payment webhook, you would normally need to deploy it to a public server. ngrok skips that step by giving your local server a public internet address instantly. The tool combines several functions: it acts as a reverse proxy (forwarding public requests to your local machine), a firewall, and an API gateway. It can also capture and display all traffic flowing through it, which makes it useful for debugging webhooks, HTTP callbacks sent by external services like Stripe or GitHub when something happens. Common uses include demoing a local app to a client without deploying it, testing webhooks during development, connecting securely to APIs or databases inside private networks, and running IoT device gateways. Note: this specific repository is the archived version 1 from 2013-2016 and is no longer maintained. The current ngrok service and its SDKs are developed separately at the ngrok GitHub organization. The tech stack is Go.
