JustPy

JustPy is a Python web framework that allows developers to build interactive web applications without extensive front-end programming. It emphasizes an object-oriented, component-based approach, aligning with the low-code/no-code concept by abstracting away much of the JavaScript. It provides HTML components and the ability to create custom components, which can be seen as a form of UI building. It also supports integration with various data sources and APIs through Python. While it's not a visual drag-and-drop builder in the same vein as Retool, its component-based approach and Python-only development for web UIs provide a similar value proposition for internal tools.
