Which is the best site analysis Tool in SEO ?

I found SEO MOZ pro as one of the best tool to analyse the website. This software let you optimize the website in all situations. Moz Pro software has a Keyword Planner, SEO Audit functionality, error-detection technique and suggestion section that make it one of the best SEO tool among its competitor's. https://www.filerepairtools.com/moz-pro-seo-tool.html
