I'd add that third-party dependencies are sometimes useful. Especially when they aren't served from the same location which gives and opportunities for the browser to open more HTTP connections: https://www.linkedin.com/pulse/why-does-your-browser-limit-n...

You may want to try https://www.sitelint.com/ for SEO testing, but not only. We have just launched a platform recently and the main idea behind is that all audits are performed on the client-side, as opposed to crawling. I'm happy to get the feedback and improve anything that can be improved there.
