🚀 How to Get Started

Getting started with ngrok is straightforward. First, download the ngrok client from the official website and install it on your local machine. Once installed, you’ll need to authenticate your ngrok account by running the ngrok authtoken command, followed by your authtoken (found on your ngrok dashboard). To expose a local web server, simply run ngrok http [port], replacing [port] with the port number your server is running on (e.g., ngrok http 8000). ngrok will then provide a public URL that you can use to access your local server from anywhere. For TCP tunneling, use the command ngrok tcp [port]. You can also specify a custom domain by using the -domain flag (e.g., ngrok http -domain=example.com 80). To secure your tunnel with TLS, use the ngrok tls [port] command. For more advanced configurations, such as setting up traffic policies or using reserved tunnels, refer to the ngrok documentation. With these simple steps, you can quickly and easily expose your local services to the internet.
