Question

Can I use pagespeed insights for my localhost website or offline?

Answer 1

Yes.

Use the "Lighthouse" tab from your google chrome dev tools.

This is a great starter tutorial on how to do that: https://www.youtube.com/watch?v=5fLW5Q5ODiE

Edit: user izogfif pointed out the "Audit" tab was replaced by "Lighthouse".
