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.
