Nodejs or python, pageload and waterfall chart?

Question

Python

Guys, tell me a couple of points.
I want to get the site loading speed and page weight by url and get a list of requests.
In python or nodejs.
Google for the second day. And I write my crutches, but they all show nonsense. Therefore, there may be some approximately ready-made libraries.

all sorts of newfangled bokeh, dash, simple graphos, condo mathplotlib , and 3djs correspondence somewhere,
but for requests "like a browser" you need, like, a browser:
Selenium, Phantom and other JS headless
