How to install Ngrok in Kali Linux

In the world of web development, showcasing your locally hosted projects to clients and stakeholders before their official launch is crucial. However, making a local development server accessible on the internet can be a challenging task, involving port forwarding and owning domain names or static IP addresses. This is where Ngrok comes in.

Ngrok is a multi-platform application that enables developers to easily forward their local development server to the internet without the need for complex configurations. In this article, we will explore Ngrok, its installation process on Kali Linux, and how to leverage its capabilities effectively.

Introduction to Ngrok

Ngrok is a powerful tool that provides developers with the ability to expose their local development servers to the internet securely. It acts as a tunneling service, hosting locally hosted web servers under a subdomain of With Ngrok, developers can easily share their projects with clients, collaborate on testing, and gather feedback before deploying them to production environments.

The Need for Ngrok in Web Development

The use of Ngrok in web development offers several advantages. Firstly, it eliminates the complexities associated with port forwarding, which often involves configuring routers and firewall settings. Ngrok simplifies this process, allowing developers to focus on their projects rather than network configurations.

Secondly, Ngrok enables developers to showcase their projects to clients and stakeholders without the need for domain names or static IP addresses. This feature is particularly beneficial in situations where the project is still in the development phase or when the client does not possess a technical background to set up port forwarding.

Installing Ngrok on Kali Linux

Before utilizing Ngrok on Kali Linux, it is necessary to install the application. The following steps outline the installation process:

  1. Open your preferred web browser and navigate to the official Ngrok download page.
  2. On the download page, click on the “Download for Linux” option since we are using Kali Linux.
  3. Once the download is complete, locate the downloaded ZIP file in your “Downloads” directory.
  4. Open a terminal and navigate to the “Downloads” directory using the following command: cd Downloads
  5. Extract the contents of the ZIP file using the command: unzip ngrok-stable*zip
  6. Grant executable permission to the Ngrok binary by running the command: chmod +x ngrok

Now that Ngrok is installed, we can proceed with configuring it.

Downloading and Configuring Ngrok

To utilize Ngrok’s features, we need to set up authentication with an Ngrok API token. Follow these steps to obtain and configure the API token:

  1. Open your web browser and visit the Ngrok signup page.
  2. Fill in the required fields, including your name and email address. Optionally, you can use a disposable mail address for verification purposes.
  3. Complete the signup process and verify your email address.
  4. After verification, you can find your Ngrok API token in the “Your Authentication” section of the sidebar.
  5. Copy the command provided, which includes your API token, to set up Ngrok authentication. The command should resemble the following: ./ngrok authtoken 1xyqb*****************25PTTHqMpHqB

With Ngrok authenticated, we are ready to run the application and forward our locally hosted websites to the internet.

Setting up Ngrok Authentication

Authentication is a crucial step in utilizing Ngrok’s services. By setting up authentication, you ensure that only authorized individuals can access your Ngrok tunnels. To authenticate Ngrok, follow these steps:

  1. Obtain your Ngrok API token by signing up on the Ngrok website, as explained in the previous section.
  2. In a terminal window, navigate to the directory where the Ngrok binary is located.
  3. Run the following command, replacing <your-auth-token> with your actual API token: ./ngrok authtoken <your-auth-token>

By completing these steps, you have successfully authenticated Ngrok and are ready to use its features

Utilizing Ngrok on Kali Linux

With Ngrok properly installed and authenticated, we can begin leveraging its capabilities. To use Ngrok on Kali Linux, follow these steps:

  1. Ensure you have a locally hosted website or web server running on your Kali Linux system.
  2. Open a new terminal window and navigate to the directory where your website files are located.
  3. Start a localhost server on port 80 (or a different port if necessary) using the following command: sudo python3 -m http.server 80
  4. Leave the terminal window running the localhost server open and switch back to the previous terminal window (where Ngrok is set up).
  5. Run the following command to start Ngrok and forward your local server to the internet: ./ngrok http 80

Accessing Locally Hosted Websites with Ngrok

Ngrok simplifies the process of accessing locally hosted websites by providing a public URL that forwards traffic to your local server. To access a locally hosted website using Ngrok, follow these steps:

  1. After starting Ngrok with the appropriate configuration, you will see the forwarding link displayed in the terminal.
  2. Copy the forwarding link and open it in a web browser.
  3. Voila! You can now access your locally hosted website through the Ngrok tunnel.

Ngrok’s Benefits and Limitations

Ngrok offers several benefits to developers, such as simplified localhost forwarding, easy sharing of projects with clients, and mobility for accessing websites remotely. However, it’s crucial to be aware of its limitations and exercise caution while using it. Here are some key points to consider:

  • Advantages of Ngrok:
    • Easy setup and configuration on Kali Linux.
    • Allows forwarding of locally hosted websites without a static IP address or port forwarding.
    • Facilitates showcasing projects to clients and stakeholders before deployment.
    • Provides temporary accessibility to locally hosted websites on mobile devices.
  • Limitations and Cautionary Notes:
    • Ngrok can be misused by malicious actors for hosting phishing pages. Users should employ Ngrok responsibly and ethically.
    • The free plan of Ngrok has limitations on tunnel duration and concurrent connections.
    • Ngrok is not a permanent hosting solution. It is primarily intended for testing and development purposes.


Ngrok is a powerful tool for developers and cybersecurity enthusiasts alike. It simplifies the process of forwarding locally hosted websites to the internet, allowing easy access and sharing of projects. By following the installation steps and utilizing Ngrok on Kali Linux, you can seamlessly showcase your web development work to clients and stakeholders. However, it’s important to use Ngrok responsibly and be aware of its limitations and potential security implications.
