Fetch & Render Simulator
Tool designed to simulate the googlebot fetch & render. Will return rendered, and initial
source code (obeys the user-agent specified) and a screenshot.
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 Rich Results Test or URL Inspection tool in Search Console.
Honours robots.txt uses the google open source parser, robots.txt files are fetched fresh for each test.
If you are testing the root of a domain, it will check for vaild favicons for Google search. You can also find a quicker, stand alone tool Here.
Test results deleted after 5 mins max, tests are not logged.
Getting Blocked? site owners might well choose to block tools like this, especially if they are pretending to be Googlebot.
If you are testing your own site, you can find the IP ranges used by this tool here ttb-ipranges.json and allow list them in your firewall or security plugin.

Rendering Snapshot Strategy
Occasionally, some sites might need a longer wait time, if you find the rendered html is incomplete, try changing to 'networkidle0', if you're missing stuff.
Disabling JavaScript can be useful for testing how a page is seen without rendering, like many AI bots do, or for testing if your critical content is available without JavaScript.
Uses these excellent open source projects: Puppeter for rendering, google/robotstxt for robots.txt parsing and matching & dom2html for DOM flattening.
iframe flattening inspired by a discussion with Glenn Gabe ( @glenngabe ), of G-Squared Interactive.
Custom robots.txt suggested by John McAlpin.
