Tool to Check Original Source Code and the Rendered HTMLhttps://www.searchviu.com
A handy little tool to chack comparison of source & rendered HTML. You can pick a mobile or desktop view and gives you a quick way to see if there are differences in Title, description, robots tags canonical, content and internal links.
I haven’t had the chance to fully test it out, but the concept does sound quite handy. At the moment I use View Rendered Source for this.
