Blender is Free Software. It is free to use for everyone. Free to use for any purpose, also commercially. Blender is free to share with others, it is free to study Blender’s sources and free to make new versions.

Blender is free, forever.

This freedom is what makes the GNU GPL license so powerful and it is why it’s much more than “open source”. The license simply prevents anyone to put restrictions on Blender. That protects users as well as everyone who contribute to Blender.

If you decide to contribute to Blender, whether as Python script or as C++ code, you are required to agree on this freedom. You can keep all rights of your own work, but if you publish or sell or share Blender code, you do it under the same conditions, just as Free as Blender is.

The GPL has often be called infectious. I think that’s a negative and misleading frame. Proprietary code is infectious in ways too (try to use proprietary code in your work and face the consequences). Best is to keep the public and open domain entirely separated from your private proprietary domain. And really, both domains can live well together.

You can create bridges between the domains. This is how Blender can work with other proprietary tools or engines. The bridges (if using Blender code) have to be fully GPL compatible. The closed software such bridges lead to can not be bundled, it’s up to your own – or the user’s – concern to connect it.

In the past years, developing and selling Blender add-ons grew into quite a big market. We’ve all seen fantastic & powerful scripts doing amazing things. Great add-on coders indeed. But also: what an incredible API these C developers made for Blender!

Blender’s scripting API is an integral part of the software. Blender add-ons work, look and feel like Blender features. And as for any other Blender feature that means – it has to be free, free and free forever! Paying for an add-on can only mean access to the add-on download service… offering it to you as GNU GPL. Your freedom as a user and developer is guaranteed.

I’ve always interpreted Free Software and the GNU GPL as a means, not a goal. It just works fantastic for Blender. I’m not going to blame proprietary programs for not opening up. But I also won’t accept proprietary business to pollute our open domain. Live, and let live.

And if you think you ‘suffer from piracy’ or find it hard to do business with Free Software? Just distinguish yourselves with the proven successful free/open source business model: provide docs, training, content, frequent updates and support. Your customers will love you!

I expect that all add-on developers recognize and respect this concept. Since 2002 dozens – maybe even hundreds – of people have devoted years of their life to making Blender open and free to use for everyone. This massive effort has made it a strong and exciting program where add-ons can become massively successful. You’re standing on the shoulders of giants!

This can only work if we create a level playing field for everyone. Nobody’s code is more important than another’s. Nobody cuts a corner of the Blender play field to claim it as their territory. Nobody will plant trees here where you can’t climb in or enjoy its fruits.

Complete. Free. Forever.

Please note: I’m not a lawyer and not a license expert. Just sharing how I see this complex matter. Hopefully it helps understanding Blender’s license better. Thanks for reading!
