AppGini comes in 2 versions: the freeware version, and the professional version. The freeware version is fully working and non-expiring. There are however some limitations of this version:

• You can create up to only 4 tables per project, and up to 4 fields per table.
  
  
• You can create only one file upload field per project.
  
  
• You can not save project files, but you can download sample projects and open them normally.
