Optionally
you can also run a lighthouse test as well. Although intended to match,
parity with the Google WRS cannot be guaranteed, always confirm in
either the
Mobile-Friendly Test
or URL Inspection tool in Search Console.
Test results deleted after 5 mins max, tests are not logged.
URL is required
Fast mode takes near instant snapshots, and may miss some slower
to load content and features, turn this off if you are getting
incomplete pages.

Uses these excellent open source projects:
Puppeter
for rendering &
dom2html
for DOM flattening.
