Walker walkes aka as crawls through websites and collects performance and SEO relevant data. The results can be browsed through a very simple web interface. Apart from that they are exposed as prometheus metrics (not implemented yet).

Be careful when crawling your website with walker with aggressive settings, it might take your site down
