Requires Cache Rocket API keys in the plugin. Warmers stay editable in WordPress, not on the SaaS dashboard.
What is free vs what needs a plan
The local performance suite ships unlocked. Cloud optimization jobs and Managed CDN require a paid Cache Rocket subscription with the matching entitlements.
Full page caching with early advanced-cache.php delivery (free)
Optimize Critical Images (LCP beacon) and automatic Lazy Rendering (free)
Nulled WordPress plugins are often modified with malware, backdoors, or stolen credentials. And with Cache Rocket there is nothing to null — the full plugin is already free.
Pulled live from our GitHub releases, so you always see exactly what shipped.
The local plugin suite is free forever. A Cache Rocket account adds remote warming; WordPress Starter (€1) and Grow (€5) unlock Managed CDN and cloud optimization for connected installs.
