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.
Honour robots.txt uses the google open source parser, robots.txt files are fetched fresh for each test.
Test results deleted after 5 mins max, tests are not logged.
URL is required
