Superhero Web Framework
Build extensions to ERPNext or make your own app
The key differece in Frappe compared to other frameworks is that Frappe is that meta-data is also treated as data and is used to build front-ends very easily. Frappe comes with a full blown admin UI called the Desk that handles forms, navigation, lists, menus, permissions, file attachment and much more out of the box.
Frappe also has a plug-in architecture that can be used to build plugins to ERPNext.
Frappe Framework was designed to build ERPNext, open source ERP for managing small and medium sized businesses.
