Unlike Streamlit, which re-runs the entire script on every interaction (causing performance issues and flickering), Solara uses a reactive state model. You declare a variable (e.g., count = solara.reactive(0) ). When this variable changes, only the components dependent on that variable re-render , not the whole page. This is similar to React's useState or Vue's reactivity system. github solara

It leverages a React-style API to simplify state management and UI development for data-heavy projects. Framework Overview @solara

Solara is built on top of Reacton, a pure Python implementation of React, and utilizes ipywidgets for its UI components. Unlike many Python web frameworks designed only for small dashboards, Solara is architected to scale into large, production-grade applications. This is similar to React's useState or Vue's
