Dash

Dash is the premier open-source Python framework for building analytical web applications and interactive data science dashboards without writing JavaScript.

Dash is the original, low-code framework: it enables data scientists to build full-stack analytical web applications using pure Python. The architecture leverages three core technologies: Flask (for the web server), React.js (for UI rendering), and Plotly.js (for high-quality charting). This structure allows users to create complex, interactive dashboards—like a simple 43-line app connecting a Dropdown to a Plotly Graph—by tying modern UI components directly to their analytical code. The framework is highly trusted, offering an open-source option and an enterprise version for scaling and advanced features (e.g., Snapshot Engine, Design Kit).
