Data scientists and engineers building exploratory dashboards and apps on top of Python data tools.

Panel is an open source HoloViz framework for turning Python scripts, Jupyter notebooks, and plotting libraries into shareable web apps and dashboards.

Runs self-hosted via Bokeh server or exportable static HTML, and works inside Jupyter environments directly.

Used when a team needs rich, linked, interactive visual apps that stay in native Python and Pandas or Xarray workflows.

It integrates broadly with Matplotlib, Plotly, Bokeh, and Altair so teams are not locked into one plotting library.

Built on Bokeh for rendering and Param for reactive parameters, part of the broader HoloViz ecosystem.

Open source, BSD 3 Clause licensed, self-hosted, actively maintained by HoloViz and Anaconda with roughly 5700 GitHub stars.
