Voila
the six Ws · specification
Data scientists who want to publish a Jupyter notebook as a polished app without exposing the code.
Voila is an open source Jupyter subproject that renders a live notebook as a standalone web dashboard, hiding code cells and executing widgets interactively.
Self-hosted as a Jupyter server extension, or deployed via Docker, Binder, or any WSGI-compatible host.
Used when the fastest path from an existing analysis notebook to a shareable interactive app is needed.
It requires no rewrite of existing notebook code, just adding ipywidgets for interactivity.
Built on Jupyter Server, nbconvert, and ipywidgets for interactive components.
Open source, BSD 3 Clause licensed, self-hosted, part of the official Jupyter project with close to 6000 GitHub stars.
