Built With: The Power Behind Modern Websites

Built With

In the digital age, creating a robust and efficient website involves numerous tools and technologies. “Built with” refers to the suite of technologies, frameworks, and tools used to develop and maintain websites. Understanding what a website is built with can provide insights into its performance, functionality, and user experience.

The Importance of Knowing What a Website Is Built With

Understanding the technologies behind a website is crucial for several reasons:

  1. Performance Optimization: Knowing the tools and frameworks used can help identify performance bottlenecks and optimize loading times.
  2. Security: Identifying the software stack can highlight potential vulnerabilities and help in implementing security best practices.
  3. SEO: Certain technologies can impact a website’s SEO. For instance, knowing whether a site uses a CMS like WordPress or a JavaScript framework like React can inform SEO strategies.
  4. Development and Maintenance: For developers, understanding the existing tech stack is essential for maintenance, troubleshooting, and future development.

Common Technologies Used to Build Websites

Content Management Systems (CMS)

  • WordPress: One of the most popular CMS platforms, known for its flexibility and extensive plugin ecosystem. Ideal for blogs, e-commerce sites, and more.
  • Joomla: Another versatile CMS with a strong community, suitable for various types of websites.
  • Drupal: Known for its robustness and scalability, Drupal is often used for large and complex websites.

Front-End Technologies

  • HTML/CSS: The backbone of web pages, HTML structures the content, while CSS styles it.
  • JavaScript: A core technology for interactive features. Libraries and frameworks like jQuery, React, and Vue.js enhance JavaScript’s capabilities.
  • Responsive Design Frameworks: Frameworks like Bootstrap and Foundation help create mobile-friendly, responsive websites.

Back-End Technologies

  • Server-Side Languages: PHP, Python, Ruby, and Java are commonly used for server-side development.
  • Frameworks: Laravel (PHP), Django (Python), and Ruby on Rails (Ruby) streamline development and enhance performance.
  • Databases: MySQL, PostgreSQL, and MongoDB are popular choices for database management.

Hosting and Infrastructure

  • Web Servers: Apache and Nginx are widely used to serve web pages.
  • Cloud Hosting: AWS, Google Cloud, and Azure provide scalable hosting solutions.
  • Content Delivery Networks (CDNs): Services like Cloudflare and Akamai speed up content delivery and enhance security.

Tools to Identify What a Website Is Built With

Several tools can analyze websites and identify the technologies they use:

  • BuiltWith: A comprehensive tool that reveals a website’s tech stack, including CMS, e-commerce platforms, analytics tools, and more.
  • Wappalyzer: A browser extension that detects the technologies used on websites, including frameworks, libraries, and CMS platforms.
  • Netcraft: Offers detailed insights into web server configurations, hosting providers, and more.
  • Google Chrome Developer Tools: Built into the Chrome browser, these tools provide insights into the HTML, CSS, JavaScript, and network activities of a website.

Case Study: Analyzing a Popular Website

To illustrate, let’s analyze a popular e-commerce site like Amazon:

  1. CMS: Amazon uses a proprietary CMS tailored to its vast product catalog and user base.
  2. Front-End: The front-end is built using HTML5, CSS3, and JavaScript. Libraries like React are likely used for dynamic content rendering.
  3. Back-End: The back-end infrastructure is highly complex, utilizing Java, Python, and other languages for various services.
  4. Databases: Amazon likely uses a combination of relational databases (MySQL) and NoSQL databases (DynamoDB).
  5. Hosting and Infrastructure: Hosted on Amazon Web Services (AWS), leveraging EC2 instances, S3 for storage, and CloudFront as the CDN.


Understanding what a website is built with offers significant advantages in terms of performance, security, and SEO. With tools like BuiltWith and Wappalyzer, gaining insights into a site’s technology stack is easier than ever. As web technologies continue to evolve, staying informed about the tools and frameworks used to build websites will remain crucial for developers, marketers, and business owners alike.
