GPL, Explained: Why You Can Legally Buy WordPress Plugins at 95% Off

Every store owner who discovers a GPL plugin marketplace asks the same question first: "Is this legal? How can this cost $5 when the developer charges $300?" The short answer is yes, it is legal, and the reason is a license called the GPL that has been part of WordPress since day one.

What is the GPL?

The GNU General Public License (GPL) is a copyright license created by Richard Stallman in 1989. It grants users four freedoms:

  1. The freedom to run the software for any purpose.
  2. The freedom to study the source code.
  3. The freedom to redistribute copies.
  4. The freedom to distribute modified versions.

These freedoms are guaranteed by law. Anyone who releases software under the GPL is granting you these freedoms, and cannot revoke them.

How does the GPL apply to WordPress?

WordPress itself is licensed under GPL version 2. When you install WordPress, you inherit the GPL freedoms. And because of a legal doctrine called copyleft, any code that runs as a plugin or theme on top of WordPress inherits the same license.

This is why every WordPress plugin - even ones sold for hundreds of dollars - is technically GPL. Elementor Pro is GPL. Yoast SEO Premium is GPL. WooCommerce Subscriptions is GPL. They have to be, because they extend WordPress.

What does the developer sell, then?

If the code itself is freely redistributable, what is the developer charging for? Three things:

  • Support: direct access to their engineers when something breaks.
  • Updates via their license server: a convenient one-click update mechanism.
  • SaaS features: some plugins have cloud components (like Elementor's template cloud) that require an active license to access.

The plugin code itself is redistributable, but the developer's premium services are not. That is the trade-off.

Why does WooPlugins cost less?

We buy the plugin from the original developer once, then share the download with our community under the same GPL license. Everyone gets the same working plugin. Our costs are a fraction of running direct customer support for every plugin in the catalog, so we can pass the savings on.

What you get from us:

  • The exact same plugin file as the official version.
  • Regular updates as new versions ship.
  • Unlimited use on your own sites and client projects.
  • Our support for anything related to your purchase and download.

What you do not get from us:

  • The original developer's premium support.
  • Access to cloud services tied to their license server.
  • Warranty that a plugin will work in your specific environment.

Is this legal in my country?

The GPL is an international license. It has been tested in courts in the US, EU, and Asia, and it has held up every time. Redistributing GPL software is legal everywhere WordPress itself is legal to run.

Is this ethical?

This is where opinions differ. Original developers deserve to earn a living from their work, and GPL marketplaces do reduce their revenue. On the other hand, GPL was created specifically to prevent knowledge monopolies. Both viewpoints are valid.

Our position is that we always recommend buying direct if you can afford it and need premium support. For small stores and hobbyist projects that would never afford a $300 plugin, GPL marketplaces are the difference between using a premium tool and going without.
