SpeedyCache

Tested with SpeedyCache 1.4.3 and AI Puffer 2.5.15, from ChatGPT and Claude, on 25 October 2026. Enable SpeedyCache’s AI Abilities option first. Native abilities require WordPress 6.9 or later and a connected user with permission to manage settings.

SpeedyCache’s cached-page and size counters can be stale. They do not prove whether a particular page is cached. A preload’s empty queue means requests were processed; it does not prove every page was successfully cached.

Super Page Cache

Tested with Super Page Cache 5.3.8 and AI Puffer 2.5.15, from ChatGPT and Claude, on 25 October 2026. These tests used local disk caching without a Cloudflare connection.

Cloudflare edge purges, Pro cache tags and post-related archive purges have not been verified. A preload job’s completion state is separate from its per-URL results, which are in the plugin log.

WP Fastest Cache

Tested with WP Fastest Cache 1.5.3 and AI Puffer 2.5.15, from ChatGPT and Claude, on 25 October 2026.

The Logged-in Users and Mobile checkboxes exclude those visitors from cached pages when enabled. The recipe reads saved values; it does not prove whether a particular request receives cached HTML. AI Puffer 2.5.16 or later supports the linked HTML settings; page-cache clearing is still separate. An object-cache flush does not clear WP Fastest Cache’s page cache.

Redis Object Cache

Tested with Redis Object Cache 3.0.0 and AI Puffer Free and Premium 2.5.15, from ChatGPT and Claude, on 25 October 2026, using separate dedicated Redis instances.

Your host must already have configured Redis. Checking WordPress’s external-cache flag confirms its drop-in is in use; it does not measure Redis connection health, latency or hit rate.

Before clearing, have your host confirm a dedicated Redis database or an appropriately scoped flush configuration. By default, Redis Object Cache clears the entire selected database, including other prefixes. A unique prefix alone does not isolate a flush. This clears object data, not WP Fastest Cache’s cached HTML or a CDN cache; posts and saved settings remain intact.

WP-Optimize

Tested with WP-Optimize 4.7.0 and AI Puffer Free and Premium 2.5.15, from ChatGPT and Claude, on 25 October 2026.

This reads the saved page-cache configuration. It does not test page delivery. WP-Optimize’s page-cache purge is not currently offered; an object-cache flush does not clear its cached HTML. Database cleanup, image compression and cache activation are outside these workflows. Supported lifetime and exclusion changes use the separate recipe above.

Breeze

Tested with Breeze 2.6.3 and AI Puffer Free and Premium 2.5.15, from ChatGPT and Claude, on 25 October 2026, using local disk caching with Varnish auto-purge off and no Cloudflare connection.

Breeze’s saved cache lifetime is in minutes. API tokens remain redacted. Its full-purge handler can also clear minified files and WordPress’s object cache and invoke configured external purge integrations. The tests verified real local cached pages were removed; they do not establish successful Varnish or Cloudflare purges. If an external object cache is installed, ask your host to confirm its flush is isolated to the intended site or database first.

LiteSpeed Cache

Tested with LiteSpeed Cache 7.9.2 on OpenLiteSpeed 1.9.3 and AI Puffer Free and Premium 2.5.15, from ChatGPT and Claude, on 25 October 2026.

The tests verified a real cache hit, a miss after purging, then a fresh hit. LiteSpeed’s server page cache requires a compatible server; a successful plugin-handler response alone does not prove that the server cleared it. Object caches and CDN caches are separate.

WP Super Cache

Tested with WP Super Cache 3.1.4 in Simple/PHP mode and AI Puffer Free and Premium 2.5.15, from ChatGPT and Claude, on 25 October 2026.

With AI Puffer 2.5.16 or later, settings changes can update expiry and exclusions through the plugin’s registered REST routes. Preserve the current email-notification preference when changing expiry. Reads and purges also use its native APIs. An empty status response means no warnings were returned; it does not prove a page was cached. Purges removed real cached HTML while preserving posts and settings. Expert/mod_rewrite mode and preload execution were not tested.

Other tested cache commands

Tested on 15 October 2026, on Free and paid sites, with each plugin installed.

These use AI Puffer’s WP-CLI commands, with no SSH. Recipe: Clear your site’s caches.

At Standard, cache changes wait for approval in WordPress. At Trusted, offered changes run directly. Each successful ability or command uses one website action, including status reads. A CDN or your host’s own cache may need clearing separately.

SpeedyCache’s file/CDN inspection, post-ID purge and exclusion removal have not been tested.
