What Is WordPress GPL License – Everything You Should Know

To successfully start a sustainable business on WordPress, it’s essential to understand the licensing system (GPL) that governs this platform. It not only explains how WordPress can be used but also plays a crucial role in maintaining a peaceful community for users and developers.

Understanding GPL is a must, especially for professional developers and those who want to build their business sites using various WordPress plugins. Yet many people tend to show disinterest in caring about GPL, which causes them to suffer a lot in the end.

In this article, we’ll cover everything about the WordPress GPL license systems in detail, which you must know or read out at least once in a lifetime. Get started!

What Is GPL License?

GPL stands for General Public License. It’s a widely used licensing system that allows people to modify someone else’s software and resell/redistribute it to customers. As WordPress is licensed under GPL, you can modify and redistribute any WordPress themes and plugins.

Since WordPress is committed to open-source, this role applies to any free or premium WordPress themes and plugins.

The reasons for WordPress releasing under the GPL are both practical and idealistic. WordPress was born of the very freedom mentioned earlier. The predecessor to the WordPress project, b2/cafelog, was also an open source project.

Freedoms the WordPress GPL License Grants You

If you go to the About page of WordPress.org, the GPL licensing system grants you four key freedoms, which are counted as key strengths of this content management system. Let’s take a look at them below.

1. Freedom to Build: Anything You Imagine

WordPress allows you to create any type of website, including a personal portfolio, online store, or community forum. For example, a small business can create an e-commerce site, while a non-profit organization can use it to build an informational portal.

2. Freedom to Learn: Explore How It Works

With GPL, you can access the source code, the underlying blueprint that makes WordPress tick. This allows developers to study how it works, modify it for specific needs, and even contribute improvements back to the community.

3. Freedom to Change: Make WordPress Your Own

GPL empowers you to build derivative works based on the core software. This could be anything from a niche plugin that optimizes image SEO to a full-fledged theme that transforms your website’s visual identity. But here’s the twist – the GPL requires your derivative work to inherit the same open-source spirit.

4. Freedom to Share: Spread the WordPress Love

The beauty of WordPress extends to sharing it with others. You can redistribute copies of the software, allowing friends and colleagues to set up their websites with ease. Users can also distribute their modified versions of WordPress to others. This ensures that improvements and innovations can benefit the wider WordPress community.

GPL vs. Other Open Source Licenses (With a Comparison Table)

After the above discussion, hope you now have a clear idea of what the GPL license is. There are several other types of licensing systems as well. For further understanding, let’s take a quick look at the differences between GPL and other open-source licenses.

Feature	GPL	LGPL	BSD License	MIT License
Copyleft	Yes	No	No	No
Derivative Works	Must be GPL-licensed	Can be closed source	Can be open or closed	Can be open or closed
Commercial Use	Allowed	Allowed	Allowed	Allowed
Focus	Open source & collaboration	Flexibility for developers	Wider adoption	Ease of use
Restrictions	Modifying GPL code requires keeping it open source	Less restrictive than GPL	Few restrictions, but copyright notice is required	Very permissive, minimal obligations
Suitability	Projects where source code openness and community contribution are crucial	Libraries or components used in both open-source and closed-source projects	Projects seeking widespread adoption and potential commercialization	Small code snippets or projects where ease of use and minimal restrictions are desired

The GNU General Public License (GPL) is a popular open-source license, but it’s not the only option. Let’s have a look at the three other major licenses that uphold the open-source spirit as well.

LGPL (GNU Lesser General Public License): More permissive than GPL. Allows linking GPL code with proprietary software without requiring the proprietary code itself to be open source.

BSD License (Berkeley Software Distribution License): Highly permissive. Grants users broad freedom to use, modify, and distribute the code, even for commercial purposes, with or without keeping the source code open.

MIT License (Massachusetts Institute of Technology License): Extremely permissive. Similar to BSD, grants users almost complete freedom with minimal obligations. Requires copyright and license notice to be included in derivative works.

The Power of GPL in Action: WordPress Themes and Plugins

Consider the vast library of WordPress plugins and themes. These extensions often rely on core WordPress functionalities to operate. Since they’re derivative works, they inherit the GPL license. This ensures that themes and plugins remain open-source within the WordPress ecosystem.

For instance, let’s say you develop a plugin that adds a sleek contact form to WordPress websites. Under GPL, users can freely download and install your plugin. They can even modify the code to customize the form’s appearance or functionality, perhaps adding a CAPTCHA verification for spam protection.

While you can’t restrict users from modifying or redistributing your GPL-licensed plugin, you can offer additional services like premium support or automatic updates to provide value beyond the core functionality.

Benefits of the WordPress GPL License System for Users, Developers, and the Community

The GPL license isn’t just about free software – it’s about creating a win-win situation. Users benefit from a vast ecosystem of free and customizable tools. Developers have the opportunity to contribute, innovate, and build sustainable businesses.

Thus, the entire WordPress community flourishes. Let’s now take a look at the benefits of the WordPress GPL licensing system for different groups of people.

Benefits for Users

Free software, a vast library of customizable plugins and themes, and the freedom to tinker with the code – that’s the magic of GPL for users. You can build your dream website without breaking the bank and even modify things to fit your specific needs.

Benefits for Developers

GPL opens doors for developers who want to make their mark. They can contribute to the core project and innovate by building upon existing code. They can even build a business by offering premium support or custom development services for their GPL-licensed creations.

Now of course we know that these companies can make millions of tens of millions of dollars while being GPL, and it’s amazing to be able to point to that. I love pointing to the experience of those people who are GPL when people come to me and they’re scared about open sourcing their work.

Benefits for Community

With open access to the code, developers worldwide can work together to improve WordPress. The open-source spirit promotes a culture of sharing and collaboration, leading to a constant stream of improvements. This results in a wider variety of plugins and themes, and a richer experience for everyone who uses WordPress.

…software is repaired, advanced, and extended faster and better when it’s open. When more people can share it, inspect it, tweak it, and pass it along, you get better and stronger software. Innovation, it turns out, works better with more people collaborating than when less do.

So, the next time you leverage the power of WordPress, remember the invisible force behind it – the GPL license that ensures a vibrant and ever-evolving platform for everyone.

The Challenges of Dealing with WordPress GPL License

While the GPL license unlocks a treasure of benefits in WordPress, it’s not without its complexities. Here’s a peek into some of the gray areas you might encounter:

Derivative Works vs. Bundled Resources

The line can blur between a derivative work (which inherits the GPL) and resources bundled with a plugin or theme (like images or fonts). These resources might have separate licenses.

Attribution Requirements

Some GPL licenses might require you to provide attribution (mention the original author) when using their code. Understanding these requirements is crucial.

Modifications and Sharing

While GPL grants you the freedom to modify GPL-licensed code, there can be confusion about how much you can modify it before it’s considered a derivative work that requires separate licensing.

GPL and Commercial Use

Although GPL allows commercial use of modified code, some users might misinterpret this and believe they can redistribute paid plugins for free. It’s important to clarify that using a plugin for commercial gain and freely distributing it are two different things.

Tips for Smooth Sailing with GPL

By following the below tips and familiarizing yourself with the resources available, you can confidently navigate the open-source world of WordPress. Let’s leverage the full potential of the GPL license.

• Consult the Official Resources: The WordPress license page (https://wordpress.org/about/license/) is a great starting point for understanding the specifics of GPL as it applies to WordPress.

• Seek Legal Guidance for Complexities: For intricate scenarios, consulting a lawyer specializing in open-source licensing can provide valuable insights and ensure you’re on solid legal ground.

• Embrace the Open-Source Community: The WordPress community thrives on collaboration. Don’t hesitate to reach out to developers or forums if you have questions about specific licenses.

• Know Your Limits: Some GPL licenses require attribution (crediting the original author). Be mindful of these requirements. Similarly, understand the boundaries of modifying GPL code. Extensive changes might create a derivative work requiring separate licensing.

Clear Up the Confusion Between Nulled and GPL Software

When it comes to WordPress plugins and themes, two options can cause confusion: nulled software and GPL-licensed software. Both might appear to offer free tools, but understanding the key differences is crucial for a secure and successful WordPress experience.

Nulled software is often illegally obtained from unreliable sources. These sources can inject malicious code into the plugin, putting your website at risk of data breaches, spam attacks, or even complete website breakdowns.

Unlike legitimate developers who provide updates and bug fixes, nulled software remains stagnant. You’ll not get any support or future updates of the product.

Moreover, using nulled software is essentially stealing. Developers dedicate time and effort to creating these tools, and they deserve to be compensated for their work. By using nulled plugins, you deprive them of their rightful income.

Important: Copyright laws protect intellectual property. Using nulled software can lead to legal trouble if caught.

Choosing the Right Path: Nulled vs GPL-Licensed Software

While nulled software might seem tempting initially, the risks far outweigh the benefits. GPL-licensed software offers a safe, ethical, and feature-rich alternative. Here’s why it’s the clear winner:

• Free and Secure: GPL offers a vast collection of secure plugins that won’t compromise your website’s safety.

• Support the Community: Choosing GPL empowers developers and nurtures innovation within the WordPress community.

• Long-Term Benefits: With GPL, you receive regular updates and support, ensuring a smooth and secure experience.
