## Questions & answers

### Which edition is right for me?

If you're an individual doing personal experiments, a developer of free and open-source software, a student or a researcher, pick the Free Edition. If you're a freelancer, a small game studio, a small marketing or webdesign agency, or a similar business, pick the Professional Edition.

### Is it free of charge?

In a nutshell: it's free of charge if you write free software.

The Free Edition is unsuitable for most commercial users. It's [AGPL](./license/agpl-3.0.md)-licensed: any software written with the Free Edition must be free as well. If you write non-free software, use the Professional Edition instead.

You may use the Professional Edition to create various kinds of commercial, proprietary AR experiences. However, you may not sublicense it nor transfer your license to anyone. Additionally, you may not use it to create any product that competes with this software, not even a "as-a-service" style of product (e.g., SaaS). Please read the [license](./license/PolyForm-Perimeter-1.0.0-1.md) for more information.
