⚡Tunnelite

Tunnelite is a .NET tool that lets you set up a secure connection between a public web address and an application running on your local machine. It effectively makes your local app accessible from the internet.

🚀 Use Cases

• Exposing locally-hosted web applications to the internet for testing or demo purposes.
• Quickly sharing dev builds during hackathons.
• Testing and debugging webhook integrations.
• Providing internet access to services running behind firewalls without exposing incoming ports.

📄 Installation

To install Tunnelite as a global tool, use the following command:

dotnet tool install --global Tunnelite

Once installed, you can use the tunnelite command to create a tunnel to your local application:

tunnelite http://localhost:3000

This command returns a public URL with an auto-generated subdomain.

🔍 How It Works

Tunnelite creates a bridge between your local application and the internet using a websocket connection. It streams incoming data from a public URL directly to your local server, making your local app accessible from anywhere.

The managed version of Tunnelite supports http(s) and ws(s) tunneling. If you need TCP tunneling, you'll have to host the server yourself.

Self-Hosting Requirements

To set up your own Tunnelite server, you'll need:

• Wildcard SSL certificate for your domain
• Wildcard DNS record pointing to your server's IP address

These allow Tunnelite to create secure subdomains for your tunnels and properly route traffic to your self-hosted server.
