No comments on 12 Best WordPress Cache Plugins for 2026: Ranked by Features & Speed

Introduction

There are only two WordPress cache plugins you need: one for Nginx/Apache servers and one for LiteSpeed servers. Based on Chrome’s UX report and over a decade of experience, FlyingPress and LiteSpeed Cache outperform all others by offering more features that directly optimize core web vitals.

Both integrate powerful CDNs—FlyingCDN (Cloudflare Enterprise) and QUIC.cloud—and include unique tools like local hosting of fonts, preloading LCP images, and server‐side caching. In contrast, other solutions such as WP Rocket fall behind in feature set, and SiteGround Speed Optimizer lacks essential optimizations like delaying JavaScript or removing unused CSS.
