WordPress: The Open Source Powerhouse

An Introduction to WordPress as Open Source Software

When you hear the term “WordPress,” you might immediately think of blogging or website building. But there’s more to WordPress than meets the eye. At its core, WordPress is an open source Content Management System (CMS) that epitomizes the principles and advantages of Free Open Source Software (FOSS). This page delves into the open source aspects of WordPress, exploring how it has revolutionized web development and why it remains a leading example of open source success.

What is Open Source WordPress?

WordPress, as an open source platform, is not just a tool but a community-driven project. Unlike the hosted service offered at WordPress.com, the open source WordPress software can be downloaded freely from WordPress.org. You can install it on your own web server, giving you full control to customize and manage your website.

WordPress and the Four Freedoms

In line with the FOSS philosophy, WordPress emphasizes what are known as the “Four Freedoms”:

  1. Freedom to Use: You can use WordPress however you see fit, whether it’s for a personal blog, an e-commerce site, or even an application.
  2. Freedom to Study: Because the source code is openly available, you can study how it operates, learn from it, and improve upon it.
  3. Freedom to Modify: With access to the source code, you can modify WordPress to meet your unique requirements.
  4. Freedom to Share: You are free to distribute your modified versions of WordPress, contributing to a community that collectively benefits from individual improvements.

The Community Behind WordPress

WordPress is supported by a global network of contributors who are not just developers but also designers, writers, and users. Frequent updates, thousands of plugins, and a multitude of themes are all contributions from the community.

Why Choose Open Source WordPress?


With zero licensing fees, WordPress is an economical choice. Any costs you do encounter are likely associated with premium themes or plugins, but these are optional.

Flexibility and Scalability

From blogs and portfolio sites to full-fledged e-commerce platforms, WordPress is infinitely scalable. Your site can grow and evolve without the need to switch to a different platform.


While no software can be 100% secure, the open source nature of WordPress allows for quick identification and patching of vulnerabilities.

Open Source Plugins and Themes

One of the defining features of WordPress is its expansive ecosystem of plugins and themes, many of which are also open source. These plugins and themes can be modified and even redistributed under the same open source principles that govern WordPress itself.

WordPress as an Open Source Success Story

The success of WordPress is a testament to the power of open source. From a humble blogging tool launched in 2003, it has grown to power over 40% of all websites, thanks in large part to its open source model and the community that supports it.


WordPress serves as a striking example of how open source principles can be applied to create robust, versatile, and community-driven software. As a model of open source excellence, WordPress stands as an inspiration and a tool for developers, designers, and content creators around the world.
