Panel is completely open source, available under a BSD license freely for both commercial and non-commercial use. Panel was originally developed with the support of Anaconda Inc. using funding from various commercial and government partners, and is now maintained by Anaconda developers and community contributors.
Panel is part of the HoloViz family of tools. The holoviz.org website shows how to use Panel together with other libraries to solve complex problems, with detailed tutorials and examples. You can see a variety of projects using Panel at examples.pyviz.org, and you can compare Panel to other available tools at pyviz.org or on the Background > Comparisons page.
If you have any questions or usage issues visit the Panel Discourse site. If you are interested in contributing to Panel development to help address some of the open issues, see our developer instructions to set up your development environment.
