Steps to Access Localhost on Mobile Browsers
In this article, we'll learn that viewing your mobile device applications is extremely easy in just a few steps.
Step 1: Start your applications on a local machine. Before you begin you have to start your application in your browser via localhost in your machine. Once you have done these, take a look at the URL to write down the PORT number ( Number which appears after the localhost name).
Step 2: Find your local IP address IPV4.
Open your terminal or command prompt and type ipconfig and just press enter key. You'll see like these:

Just look at your IPv4 address and write it anywhere.
Step 3: View your application on other devices.
Once you have both your PORT number and IPv4 address, simply type in your mobile or device browsers like IPv4 address:PORT. For example, 555.55.55.555:1234
The format is exactly the same. Once you run in the browser you'll see your applications.
Conclusion
Accessing localhost on mobile browsers is essential for thorough testing and development. By following the steps outlined in this guide, you can easily connect your mobile device to your local development server, ensuring that your web applications are fully optimized for mobile use. Whether you use Wi-Fi, USB tethering, or third-party tools, these methods will help you achieve a smooth and efficient workflow.
