Part of my job as a data scientist is to develop web apps. We do our work mostly on collaborative cloud platforms. What if I want to preview my app with a local browser? That's quite straightforward in a local machine, but may be tricky on cloud platforms.

Here are a couple ideas of doing in in a cloud-hosted Jupyter Lab notebook.

(1) iframe

JupyterLab support iframes natively. You can try something like as python code:

from IPython.display import IFrame
IFrame('https://statetag-pbmsdemo.datalabs.ceh.ac.uk/', width=700, height=700)

Note that some websites banned being read as iFrames.

(2) JupyterLab externsions

jupyterlab_iframe

This one is allows typing in a web address and open it as an iframe.

jupyterlab_html

This one opens HTML webpages. So you will have to save the HTML file locally.

(3) What about opening a PyQt5 GUI in Jupyter Notebook?
