  Frappe - Low Code Open Source Framework in Python and JS
  
  Frappe, pronounced fra-pay, is a full stack, batteries-included, web
  framework written in Python and Javascript with MariaDB as the database.
  It is the framework which powers ERPNext. It is pretty generic and can
  be used to build database driven apps.
