How Do I Find Out What Web Server Is Running?


Scott Campbell

Have you ever wondered what web server a website is running on? Knowing the web server can provide valuable insights into the technologies that power a website.

In this tutorial, we’ll explore different methods to find out what web server is running. Let’s dive in!

Method 1: Using Online Tools

If you’re looking for a quick and easy way to determine the web server of a website, online tools can be your best friend. These tools analyze the HTTP response headers and extract the server information. Here are some popular online tools you can use:

  • WhatIsMyIP: This tool not only provides information about your IP address but also displays the web server details.
  • Site24x7: Apart from finding out the web server, Site24x7 offers other useful features like IP geolocation and domain health” Target=”_blank”>YouGetSignal: This tool allows you to check multiple websites hosted on the same server.

Using these online tools is as simple as entering the website URL and clicking a button. They will quickly analyze the response headers and display the web server information.

Method 2: Inspecting HTTP Response Headers

If you prefer a hands-on approach, you can inspect the HTTP response headers yourself. Most modern browsers come with built-in developer tools that allow you to view network requests and their headers. Here’s how you can do it:

  • Step 1: Open your desired website in your preferred browser.
  • Step 2: Right-click on the page and select “Inspect” or “Inspect Element.”
  • Step 3: In the developer tools panel, navigate to the “Network” tab.
  • Step 4: Refresh the page to see the network requests.
  • Step 5: Click on the main request (usually the first one) to view its details.
  • Step 6: Look for the “Response Headers” section.

In the response headers, you can find a field named “Server” or “X-Powered-By” that indicates the web server technology. It might be something like Apache, Nginx, IIS, or LiteSpeed. This method not only helps you find out the web server but also provides additional information about caching, compression, and security headers.

Method 3: Using Command-Line Tools

If you’re comfortable with command-line tools, you can find out the web server using utilities like cURL or Telnet. Here’s how you can do it:

  • cURL: Open your terminal or command prompt and run the following command:
    $ curl -I
  • This will send a HEAD request to the website and display its headers. Look for the “Server” field to find out which web server is running.

  • Telnet: Telnet is another powerful tool that allows you to connect to a server and retrieve information. Open your terminal or command prompt and run the following command:
    $ telnet 80
  • This will establish a connection to the website’s server.

    Once connected, type “HEAD / HTTP/1.0” followed by two linebreaks. The server will respond with its headers, including the web server information.

With these methods at your disposal, you can easily find out what web server is running on any website. Whether you prefer online tools, inspecting HTTP response headers, or using command-line utilities, you have multiple options to satisfy your curiosity.


In this tutorial, we explored different methods to find out what web server is running. We discussed using online tools like WhatIsMyIP, Site24x7, and YouGetSignal. We also learned how to inspect HTTP response headers using browser developer tools and how to use command-line utilities like cURL and Telnet.

Now that you have these techniques in your arsenal, go ahead and discover the web servers of your favorite websites!
