W3 Total Cache stores its configuration in the w3tc_options blob (cache method per layer, CDN host, browser cache TTL, extension flags) and writes cache data to several places: page cache to wp-content/cache/page_enhanced/ for the disk method, object cache and database cache to memory or disk depending on the configured engines, and CDN purge logs to its own queue. The default admin spreads each cache layer across its own settings page with separate purge buttons and aggregate stats. There is no per-URL view that shows page cache state, object cache hits, and CDN status side by side.

SleekView reads the W3TC options and indexes the page cache directory so each URL becomes a row. Page cache state, age, mobile cache flag, and the post type behind the URL appear together. Object cache and database cache surface as their own views with engine, hit ratio (when the engine reports it), and last reset timestamp. CDN extension activity becomes a queue with the file URL, action (purge or upload), and result code so failed CDN syncs sort to the top during a release.

SleekView is read-only against W3TC's data and writes only through W3TC's own functions for inline purge and reset cache actions. The plugin continues to manage cache writes and purges on its own schedule. Saved views like Page cache missing only or CDN purges failed today can be scoped per role for handing performance triage to a developer or an agency support person without giving them access to license keys or CDN provider credentials.

W3 Total Cache is the most configurable cache plugin in WordPress, which is also why it is the easiest to misconfigure. Page cache, object cache, database cache, browser cache, minify, and a CDN extension each have their own settings page, their own purge buttons, and their own quirks. The plugin reports each one accurately in isolation, but the work that performance teams actually do crosses those boundaries: which URLs are missing page cache while having a fresh object cache, which CDN syncs failed during the last release, and which pages still serve a stale mobile cache.

The default UI does not let you ask those compound questions without rotating through several settings tabs. SleekView reads the W3TC options, the cache directory, and the extension logs and presents them as joinable sources. Each layer becomes a column instead of a tab, the CDN queue becomes a sortable triage surface, and inline purge actions go through W3TC's own functions so the plugin stays authoritative.

The flexibility that makes W3 Total Cache powerful stops getting in the way of seeing what it is actually doing.
