原文外掛簡介
The most advanced free WordPress cache plugin.
Local optimizations are unlocked on activation. Connect the plugin to Cache Rocket when you want cloud CDN and Media jobs.
Cache Rocket ships a complete local performance suite — page cache, Critical Images, delay JavaScript, LazyLoad, custom CDN rewriting, database cleanup, and remote cache warming — free forever.
Local suite is free
Page cache, file optimization, LazyLoad, custom CDN rewriting, database cleanup, and warmer management in wp-admin are unlocked on activation.

What you get
Remote cache warmers managed from wp-admin
Local page cache with optional early advanced-cache delivery
File optimization, LazyLoad, custom CDN rewriting, and database cleanup
Managed CDN, cloud image optimization, Critical CSS, LQIP, and PageSpeed with a connected account
API-key auth against your Cache Rocket account
Page cache
Caches home, posts, pages, categories, tags, archives, and optional WooCommerce shop/product/taxonomy pages. Choose standard PHP delivery or early advanced-cache.php delivery.
Cached HTML is stored under wp-content/cache/cacherocket/.
These requests are never cached:
Logged-in users (unless you explicitly allow it), admin screens, AJAX, and cron
Non-GET requests and preview / Customizer requests
WooCommerce cart, checkout, and account pages
Requests with cart or logged-in cookies
Paths, cookies, or user agents you exclude in Cache settings
Individual posts, pages, and other public content types with Do not cache enabled in the editor
Pages when DONOTCACHEPAGE is defined
Cloud optimization
With API keys connected, Cache Rocket can optimize assets in the cloud and serve them from Cache Rocket CDN automatically (no hostname to configure):
Image optimization — WebP/AVIF on img.cacherocket.com
LQIP — low-quality image placeholders
Critical CSS — above-the-fold CSS on assets.cacherocket.com
PageSpeed Insights — Lighthouse audits from the Media page
Quotas are enforced by the Cache Rocket API, not by locking local plugin code. Optional custom CDN rewriting (your own hostnames) lives under Advanced and is fully available in this plugin.
Compatibility
If another page-cache plugin is active (WP Rocket, W3 Total Cache, LiteSpeed Cache, WP Super Cache, and similar), Cache Rocket page caching turns off automatically. Cache warming and the rest of the suite still work alongside those plugins.
Never run two page caches at once.
Open source
GPLv2. Full source on GitHub. Product page and changelog: cacherocket.com/wordpress.
External services
This plugin connects to external services to provide remote cache warming and optional cloud optimizations.
Cache Rocket API
What it is / used for: Account authentication, plan/usage sync, remote cache warmers, and cloud optimization jobs (image optimization, LQIP, Critical CSS, PageSpeed). Managed CDN delivery for optimized assets uses Cache Rocket edge hostnames (img.cacherocket.com, assets.cacherocket.com).
When / what data is sent: When you save API keys, sync plan, warm URLs, manage warmers, queue cloud jobs, clear cloud assets, or uninstall the plugin. Typical payloads include your site URL, API credentials you configured, warmer settings, and selected page/media URLs needed for the requested job. A lightweight install heartbeat / disconnect notice may be sent when connected.

Google Fonts (optional)
What it is / used for: When Self-host Google Fonts is enabled under File Optimization, the plugin downloads Google Fonts CSS and font files so they can be served from your site instead of Google’s servers.
When / what data is sent: On front-end page loads that include Google Fonts stylesheet links (until the files are cached locally). The request is a standard HTTP fetch of the font CSS/font files; no WordPress user account data is sent.
