Speed of Light is an all-in-one WordPress performance plugin. It combines three layers of caching — a static disk page cache, a built-in Redis object cache, and full-page caching at Cloudflare's edge (on the free plan) — with automatic CSS, JavaScript, image, and font optimization. A real-browser cloud engine works out exactly what each page needs, and Autopilot applies the safe fixes for you. The result: green Core Web Vitals without a developer, a stack of plugins, or a monthly CDN bill.
