Dash Open Source

Dash is a productive framework for building web applications with highly custom user interfaces.

Install for Python / Install for R

Written on top of Flask, Plotly.js, and React.js, Dash is a user framework for creating interactive analytical web applications for data visualization in pure Python or R. It provides 100’s of charts, graphs, and UI controls, so you can build highly custom analytic apps in just a few lines of code.

Through a couple of simple patterns, Dash abstracts away all of the technologies and protocols that are required to build an interactive web-based application. It is simple enough that you can build a user interface around your code in an afternoon. Dash apps are rendered in the web browser. You can easily deploy them and share them through URLs.

We're strong believers that the future of technical computing and business intelligence is open source. We develop, expand, and maintain a number of open-source graphing libraries and data visualization tools for free, enabling us to amplify the collaboration and freedom inherent to open source. Those who use Python or R for data analysis, data exploration, visualization, modeling, instrument control, and reporting will find immediate use for Dash. Open-source under MIT licensing, Dash is immediately available for both Python and R.
