You can expose a local development server to the public internet by establishing an SSH-based reverse tunnel. This creates a secure connection from your localhost to a public endpoint without requiring complex network configuration.

SSH reverse tunneling is a technique that securely maps a remote public port to a local listening port. You need it for webhooks when external services like Stripe or GitHub must send real-time callbacks directly to your local machine.

No software installation is required to create a localhost tunnel because the process relies entirely on your existing SSH client. You just need an active SSH client and a local service listening on a specified port.

You can secure an exposed local service using basic authentication, bearer tokens, and IP whitelisting. These flexible access control mechanisms ensure your publicly accessible localhost tunnel remains protected from unauthorized requests.

The best way to share a local web application demo is by using an SSH-based reverse tunnel. This approach instantly provides a public URL that mirrors your local service, facilitating collaborative development sessions without permanent setup.

If your local service is not running, the SSH tunnel cannot successfully map the public endpoint to your localhost. An active local service listening on the specified port is a strict prerequisite for establishing the secure connection.
