Shiny for Python is a reactive web application framework from Posit for building interactive dashboards and data apps in pure Python, built on Starlette and asyncio. It supports inputs/outputs with automatic reactive re-rendering, UI components, theming, custom JavaScript components, and AI chat interfaces.

Use cases

• build interactive dashboards in python
• create a data app with sliders and plots
• build a streaming llm chatbot interface in python
• prototype an interactive data visualization app
• deploy a python web app without writing javascript
• build a reactive analytics dashboard with plotly
• query data with natural language ai chat

When to choose

• you want reactive python web apps without manual state management
• you are a data scientist building dashboards or data apps
• you want to prototype quickly but scale to production apps
• you need chatbot or gen-ai interfaces in python

When to avoid

• you need a traditional REST API backend
• you want full control over frontend rendering with a JS framework like React
• you need a static site rather than a server-backed interactive app
