Voila
Voilà is a tool that converts Jupyter notebooks into standalone interactive web applications. It renders notebook cells as HTML web components, preserving live widgets while stripping source code by default, and gives each viewer a dedicated Jupyter kernel for isolated widget state and callback execution.
The project runs as a Jupyter server extension, reusing existing server infrastructure for notebook serving and authentication. It supports directory-based notebook hosting, serving all notebooks in a folder as a browsable collection of web applications from a single command. Voilà also provides template-based theming through Jinja2 templates and static asset overrides, along with tag-based cell filtering to control which cells are visible in the rendered output.
Additional capabilities include kernel preheating to reduce startup latency, resource management for kernel lifecycle and idle timeouts, multi-language kernel support, and deployment options ranging from standalone servers to tunneling via ngrok. A JupyterLab preview feature allows authors to see a live Voilà rendering of their notebook during development.
