How it works
The open-source libraries are free and very capable: dozens of chart types, interactive zooming and filtering, and publication-quality output. Dash Enterprise adds deployment, authentication, and collaboration features for organisations that need to run many apps in production, with support and governance. Plotly also offers a cloud service for hosting and sharing charts.
Plotly's open-source libraries are free forever, and Dash Enterprise is priced by quote. It is a strong pick for data teams that want interactive, code-built dashboards and apps, though it requires programming skill and more setup than a drag-and-drop BI tool.
