WP Fastest Cache is free on wp.org, unlike WP Rocket, but adds no visitor-facing WordPress dependency of its own either way — its CSS/JS minify-and-combine output and, when a CDN endpoint is configured, its CDN URL rewriting both produce plain markup a static build captures as-is. Its own page cache carries the same conflict shape already established for LiteSpeed Cache, WP Rocket, and W3 Total Cache.
Running its own page cache underneath a static site doesn't add speed — it just adds a second layer that can go stale relative to the other.
No single mode applies — WP Fastest Cache doesn't influence which serving mode a site should use; see the notes below for what it actually does.
Minified/combined CSS and JS, and (when a CDN is configured) CDN-rewritten asset URLs, are both captured in the static release as-is.
None — this plugin declares no public routes of its own.
None needed — WP Fastest Cache declares no public routes of its own.
No special setup — detected automatically once active. Consider whether you need its page-caching feature on at all alongside Static Shield's own static release.
WP Fastest Cache's own page cache running alongside Static Shield's static output can serve stale content from one layer after the other has been rebuilt, so visitors may see two different versions of the same page depending on which cache answered the request. Static Shield does not change this setting automatically — recommended: disable WP Fastest Cache's own page caching for this site (leave minify/combine and CDN rewriting on). This has not been behaviorally validated against a real install.
Static Shield Lite is free to install and inspects your actual plugins, not just what's publicly visible.
