Introduction
When it comes to web development, the programming language that powers a website can significantly affect its functionality, performance, and maintainability. One such language, often praised for its flexibility and robustness, is Perl. While languages like JavaScript, Python, and PHP dominate the web development scene, Perl in web development still holds its ground in certain use cases, especially when building dynamic, data-driven websites.
In this blog post, we will explore the world of custom web development using Perl, focusing on how websites utilise Perl in their tech stack. We will also look into the reasons why some developers choose Perl over other languages, the benefits of using Perl, and real-life examples of websites built using Perl.

What Is Perl?
Before diving into the websites using Perl, it’s essential to understand what Perl is and why it has stood the test of time in the world of web development. Perl is a high-level programming language created by Larry Wall in 1987. It was designed for text manipulation, but over the years, Perl has evolved into a versatile and powerful tool for web development, system administration, network programming, and database integration.
One key reason Perl remains relevant in custom web development is its ability to handle complex tasks such as handling large datasets, text parsing, and web scraping. In addition, Perl’s extensive library of modules, known as CPAN (Comprehensive Perl Archive Network), offers a wide range of tools to help developers build custom web applications efficiently.
5 reasons some websites still rely on perl in web development?
While Perl is not the most popular language in modern web development, there are specific reasons why some websites choose Perl in webdevelopment for their projects:
Flexibility:
Perl is known for its flexibility and adaptability, which makes it suitable for building custom solutions. Developers can use Perl to create everything from simple websites to complex, high-performance web applications.
Text Processing and Data Handling:
Perl’s original focus on text manipulation makes it ideal for tasks like data extraction, parsing, and report generation. Websites that handle large amounts of data, such as content-heavy platforms, can benefit from Perl’s capabilities.
Speed and Efficiency:
Perl is efficient in terms of performance, especially when dealing with complex tasks or large datasets. This makes it ideal for websites that require real-time data processing or quick responses to user interactions.
Legacy Systems:
Many websites and companies still rely on legacy systems built in Perl. These systems continue to be maintained and updated because of their robustness and the large codebase that exists in Perl.
Open-Source:
Perl is free to use and open-source, which makes it accessible to anyone interested in web development. This can be a significant advantage for startups or companies with limited budgets.
Websites That Use Perl
Now that we understand why Perl is still in use, let’s explore some examples of websites and companies that use Perl for custom web development:
1. DuckDuckGo
DuckDuckGo, the privacy-focused search engine, uses Perl for various aspects of its web infrastructure. Perl handles search queries and manages search results, making it an integral part of DuckDuckGo’s web stack. The combination of Perl’s efficiency and the need for robust data handling makes it an excellent choice for a search engine that processes vast amounts of data.
2. Craigslist
Craigslist, one of the oldest and most popular online classified ad websites, relies heavily on Perl. The site uses Perl to handle its backend, including managing the vast amount of listings and user-generated content. Perl’s flexibility in handling text and data makes it well-suited for Craigslist’s large and dynamic dataset.
3. IMDb
The Internet Movie Database (IMDb), which provides detailed information about movies, TV shows, actors, and directors, also uses Perl in its tech stack. Perl processes large amounts of content and metadata, ensuring that users have access to up-to-date information. IMDb benefits from Perl’s ability to manage complex data structures and ensure smooth content delivery.
4. Booking.com
Booking.com, one of the largest travel websites, utilises Perl in its backend for custom development needs. The website relies on Perl for managing user requests, handling reservations, and interacting with databases. Perl’s efficiency in processing real-time data and its ability to handle complex algorithms make it a strong contender for handling the high traffic that Booking.com experiences.
5. Slashdot
Slashdot, a popular news website focused on technology and science, is another example of a site that uses Perl. Perl plays a key role in managing the site’s content and user interactions. Slashdot’s reliance on Perl helps it deliver content efficiently while managing the large number of articles and user comments.
How Perl Is Used in Custom Web Development
In custom web development, Perl can be used in various ways to build dynamic websites and web applications. Some common use cases include:
Web Scraping and Automation
Due to its powerful text processing capabilities, Perl is widely used for web scraping. Developers can write Perl scripts to extract data from websites, process it, and store it in a structured format. This makes it ideal for building data aggregation websites or tools that gather information from multiple sources.
Building Content Management Systems (CMS)
While many modern websites use popular CMS platforms like WordPress or Drupal, Perl can also be used to build custom CMS solutions. These custom CMS platforms are tailored to the specific needs of the website and offer greater flexibility and control.
Database Interaction and Management
Perl’s support for a wide variety of databases, including MySQL, PostgreSQL, and SQLite, makes it an excellent choice for building database-driven websites. Perl can interact with databases, process queries, and manage large datasets, which is essential for building dynamic websites that rely on database interaction.
Handling Form Data and User Interactions
Perl is often used for handling form data on websites. This includes managing user inputs, processing them, and storing the information in databases. Custom validation rules can also be written in Perl to ensure that user submissions meet specific requirements.
Building Web APIs
Websites that offer API services can benefit from Perl’s ability to handle HTTP requests and responses. Developers can use Perl to create RESTful APIs that allow external applications to interact with the website’s backend.
Benefits of Using Perl in Custom Web Development
Scalability
Perl is highly scalable, making it ideal for websites that experience high traffic or require frequent updates. Its ability to handle large datasets and complex tasks ensures that websites can scale efficiently as they grow.
Active Community and CPAN Modules
Perl has a robust developer community and a vast collection of open-source modules available through CPAN. These provide developers with pre-built solutions for common tasks, saving time and effort in custom development.
Cross-Platform Compatibility
Perl is compatible with various operating systems, including Linux, Windows, and macOS. This allows developers to work in different environments without worrying about compatibility issues.
High Performance
Perl’s efficiency in processing data, especially large volumes of text and files, makes it well-suited for building high-performance websites. Websites that require real-time data processing or quick response times can benefit from Perl’s speed.
Security
Perl’s security features, such as the ability to validate inputs and protect against SQL injection attacks, make it a safe choice for building secure websites. Perl’s maturity and extensive library of security-focused modules also contribute to its reliability.
Conclusion
Perl may not be the most popular language for custom web development in the modern era, but it remains a powerful tool for certain types of websites and web applications. Websites like DuckDuckGo, Craigslist, and IMDb show that Perl is still widely used for handling complex tasks, managing large datasets, and building custom solutions. Its flexibility, performance, and extensive module library make it a valuable asset for web developers looking to create dynamic and efficient websites.
While newer technologies have gained popularity, Perl’s legacy in web development continues to influence and shape the industry. If you’re considering using Perl for your custom web development project, you can be confident that it remains a reliable, secure, and efficient choice for building high-quality web applications.
