As you probably already know, Kirby is a commercial product. You can try it as long as you want on your local machine and the source code is available on GitHub. But as soon as your want to use Kirby in production, you need to purchase a license.
To keep Kirby affordable for as many people as possible, we have decided to make it available under a personal and a commercial license. The personal license may be used for personal / non-commercial projects only. The following chart may be helpful for you to decide which license is the right one for your project.
We trust in you to support us with a legally purchased license if you like Kirby.
