What Screaming Frog is
Screaming Frog is a desktop crawler that walks your site like a search engine and reports technical problems. Running on your own machine means no crawl quota and full control over speed, headers and rendering, which matters on large or access-restricted sites. In exchange, crawl size is limited by your RAM and there is no scheduled monitoring unless you set it up yourself.
What Yoast SEO is
Yoast SEO manages the technical SEO of a WordPress site: meta tags, sitemaps, schema and content checks.
