| Pros | Near-instant page changes for visitors; Settings under Settings > Reading; Maintained by the WordPress Performance Team | Page, browser, object and CDN caching in one plugin; Minification of CSS and JavaScript; Works with many CDN providers in the free code |
| Cons | Prerendering loads pages before the click, so page scripts may run early; Behaviour depends on browser support for the Speculation Rules API | Large settings area that is easy to misconfigure; Some modules need external cache servers or CDN accounts; Pro upgrade notes appear in the free admin |
