Voilà turns Jupyter notebooks into standalone web applications.

Unlike the usual HTML-converted notebooks, each user connecting to the Voilà tornado

application gets a dedicated Jupyter kernel which can execute the callbacks to changes

in Jupyter interactive widgets.

By default, Voilà disallows execute requests from the front-end, preventing execution

of arbitrary code. By default, Voilà runs with the strip_source option, which strips out

the input cells from the rendered notebook.
