Open-Source Alternative to Retool

This looks really promising. Any idea why it says only “Internal Apps”? Would it not be suitable for an MVP for a public-facing SaaS app? Or perhaps even more than an MVP? What are the limitations that might not make it suitable for a real, production app beyond an MVP ?

Founder of ToolJet here. ToolJet can be used for building public-facing apps but our focus is only on internal tools. Building public-facing apps will require more design customisation options, a built-in database that will scale well, payments/subscription features, user management features, etc. Right now our goal is to make it easier for developers to build internal tools quickly with the help of drag and drop application builder and the ability to connect to all the possible data sources with less code.
