Component is licensed on per-developer basis.
You have to purchase a license for each human, who writes the code which directly uses the component.
If you are a single developer, most likely the single developer license is right for you.
There is no limit on the number of projects you can use the component in.
All our components are royalty free which means you can redistribute the component DLLs with your application at no extra cost.
