Vibebun Cache

Vibebun Cache speeds up WordPress by serving pages from a static disk cache and trimming what the browser has to download. Cached pages are served by an advanced-cache.php drop-in before WordPress fully loads, so repeat visits are answered in milliseconds.

Every optimization is optional and can be excluded per URL or per handle, and logged-in users bypass the cache by default so editors always see the live site.

Page caching

• Disk-based full-page cache served through a version-stamped advanced-cache.php drop-in.
• Separate cache variants for desktop and mobile.
• Marketing and analytics query parameters (for example utm_*, gclid, fbclid, mc_cid) are ignored when building the cache key, so campaign links reuse the same cached page instead of forcing a fresh render.
• Configurable cache lifetime and URL/cookie exclusion lists.
• ?vbcache debug bypass for troubleshooting a single request.

Asset optimization

• Defer, delay, minify, and combine CSS and JavaScript, with per-handle exclusions.
• Remove Unused CSS (RUCSS) generation.
• Self-host Google Fonts and optimize font loading.
• Media helpers including LCP image preloading and optional emoji script removal.

Site health and delivery

• One-click database cleanup with a schedulable maintenance task.
• Browser-cache (Cache-Control/Expires) rules via .htaccess.
• Optional persistent object cache drop-in.
• Preload Cache that crawls your sitemap or homepage links to warm the cache.
• Optional Cloudflare integration and CDN URL rewriting (see External Services).

External Services

This plugin can connect to the following third-party services. Each is optional and is only contacted when the related feature is enabled or configured. No data is sent to any external service by default.

Cloudflare API (api.cloudflare.com) Used only if you enter Cloudflare credentials and enable the Cloudflare integration. When you purge the cache or the plugin lists your zones, it sends your Cloudflare API token and zone identifier to the Cloudflare API to perform the requested cache/zone operation. No page content or visitor data is sent. Terms: https://www.cloudflare.com/website-terms/ — Privacy: https://www.cloudflare.com/privacypolicy/

Google Fonts (fonts.googleapis.com and fonts.gstatic.com) Used only if you enable “self-host Google Fonts.” Your server (not the visitor’s browser) downloads the requested font stylesheets and font files once so they can be served locally afterwards. This request includes your server’s IP address and the requested font names. After download, visitors are served the fonts from your own site. Terms: https://policies.google.com/terms — Privacy: https://policies.google.com/privacy — Google Fonts privacy: https://developers.google.com/fonts/faq/privacy

All other network requests the plugin makes (Preload Cache, Remove Unused CSS generation, and browser-cache diagnostics) are loopback requests to your own site’s URL and do not contact any third party.
