Meta Box plugin was original made in order to provide developers an easy way to create custom meta boxes and custom fields in WordPress. Now it support many field types and a lot of options for each field type. However, you need to know a little bit PHP to work with the plugin. You have to hook to rwmb_meta_boxes and add your own meta boxes and custom fields. It's quite easy for developers but not for users.
So I make Meta Box Template - an extension for Meta Box that allows you to create custom meta boxes and custom fields just by writing simple template. The template is very easy to read (similar to name: value pairs), to change later and to copy and paste into other websites if you want to.
