Yoast SEO

Source

Public — Composer (wpackagist-plugin/wordpress-seo)

Purpose

On-page SEO, metadata, XML sitemaps

Special infra

None

Public plugin (Composer slug wordpress-seo), pinned and activated in bootstrap. Yoast stores its settings and generates its XML sitemaps from the database — the sitemap is served through a rewrite, not written to disk — so there are no writable filesystem paths and no special volumes.
