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.
