## What it is
JustPy is an object-oriented, component-based high-level Python web framework that lets developers build interactive websites and GUIs entirely in Python with no front-end/JavaScript programming. It is built on Starlette/ASGI and ships with components for HTML, SVG, Quasar Material Design, Highcharts, ag-Grid, and pandas integration.

## Use cases
- build interactive web apps in pure python without javascript
- create dashboards and charts from pandas dataframes
- add a web gui to a python program
- teach web development in introductory python courses
- build data grids and tables with ag-grid from python
- create matplotlib or highcharts visualizations on a website

## When to choose
- you want a pure-Python alternative to JavaScript front-end frameworks
- you are maintaining an existing JustPy application
- you want rapid prototyping of data-driven sites with pandas, charts, and grids
- you prefer server-side event handling with no front-end/back-end split

## When to avoid
- you are starting a new project - the project is sunset and users are directed to NiceGUI
- you need guaranteed bug fixes or long-term support
- you need fine-grained control over front-end performance or client-side rendering
- you need a large active community or ecosystem

## Facets
- artifact type: framework
