Dilemmato choose the Lisence

I am Developing a new project for school.
I like to use ActiveWidgets to represent the data.
could anybody assist me which License version suit to me.
Developer license or Site license.
If possible tell the difference in between.

Thanks in Advance

ActiveWidgets is licensed per developer. If you are the only one developer who will work with ActiveWidgets - you need one Developer license. For two developers you need two developer licenses and so on. If there are many developers (>10) you can purchase a Site license which covers unlimited number of developers in a single location.
