What Is the Difference Between Local Server and Web Server?


In the world of web development, two terms that often come up are local server and web server. These are essential components that play a crucial role in hosting and serving websites.

Understanding the difference between them is vital for anyone looking to delve into web development or manage their own website. In this article, we will explore the distinctions between a local server and a web server.

Local Server

A local server, also known as a localhost or development server, is a software application that allows you to run and test your website locally on your computer. It provides an environment similar to what a live web server would offer but limited to your personal machine.

Some popular local servers include XAMPP, WAMP, and MAMP. These applications bundle together the necessary software components like Apache (web server), MySQL (database), and PHP (programming language) into one easy-to-install package.

When you set up a local server, you can access your website by typing “localhost” or “127.0.1” into your web browser’s address bar. This directs the browser to your computer’s loopback IP address, where the local server is running.

The Benefits of Using a Local Server

  • Offline Development: With a local server, you can work on your website without an internet connection. This allows for uninterrupted development even in remote areas or during network outages.
  • Rapid Iteration: Making changes to your code on a local server is much faster than uploading files to a remote web server. You can instantly see how your modifications affect the website without relying on a slow internet connection.
  • Enhanced Security: Since local servers are isolated to your computer, there is no risk of exposing your website to the public or potential security breaches during development.

Web Server

On the other hand, a web server is a powerful computer or server software that hosts websites and makes them accessible over the internet. When you visit a website, your web browser sends a request to the web server, which then responds by sending the necessary files to display the webpage.

Web servers are typically equipped with high-speed internet connections, ample storage space, and advanced security measures to handle multiple requests from users around the world. Examples of popular web servers include Apache, Nginx, and Microsoft IIS.

The Advantages of Using a Web Server

  • Global Accessibility: Websites hosted on web servers are accessible from anywhere in the world with an internet connection. This allows users to access your website 24/7 without any geographical limitations.
  • Scalability: Web servers can handle a large number of simultaneous requests from users without sacrificing performance.

    They are designed to scale resources based on demand and ensure optimal website performance under heavy traffic loads.

  • Persistent Availability: Unlike local servers that rely on your personal computer’s uptime, web servers offer continuous availability. They are designed for reliability and have redundant systems in place to minimize downtime.

Differences at a Glance

Local Server Web Server
Runs on your personal computer Hosted on a powerful server computer or cloud
Used for development and testing Makes websites accessible over the internet
Offline accessibility Global accessibility
No public access or security risks during development Takes advanced security measures to protect websites from attacks


In summary, local servers and web servers serve distinct purposes in the web development process. Local servers are ideal for offline development and testing, providing a controlled environment on your personal computer. On the other hand, web servers host websites and make them accessible to users worldwide over the internet.

Understanding the differences between these two types of servers is crucial for web developers, as it helps them choose the right environment for their specific needs. Whether you are working on a personal project or launching a professional website, knowing when to use a local server or a web server will greatly impact your workflow and overall success.

Now that you have a clear understanding of the difference between a local server and a web server, you can confidently embark on your web development journey!
