Anti-Cache Kit is a development tool for WordPress developers and designers who need to bypass all caching and optimization mechanisms during development, testing, or troubleshooting.
Development tool only. Do not leave active on production sites.
Key features
Cache and optimization management
Automatically detects, flushes, and deactivates 20+ cache plugins
Removes cache drop-ins (object-cache.php) so caches that keep working through a drop-in actually stop
Deactivates optimization plugins that interfere with debugging (Perfmatters, FlyingPress, WP Asset CleanUp, and more)
Never deactivates Query Monitor, the debugging tool you need while troubleshooting
Clears object cache (Redis, Memcached) and OPcache
Clears hosting-specific caches (SiteGround, Cloudflare, Kinsta, and Varnish on demand)
Prevents browser caching for administrators
Server-level cache prevention
Injects .htaccess rules via the WordPress markers API, no backup file needed
Disables SiteGround cache via environment variables
Sets no-cache, no-store headers at server level for all visitors
Disables ETags and mod_expires to prevent conditional caching

Code examples
Customize maintenance page:
add_filter( 'ayudawp_anticache_maintenance_data', function( $data ) { $data['heading'] = 'My Site Name'; $data['status'] = 'Updating...'; $data['message'] = 'We are deploying a new version. Back in a few minutes.'; return $data; } );

Frequently asked questions.
Is this safe to use on a live website?
Yes, with caveats. PHP-level anti-cache measures only affect administrators. However, the .htaccess rules affect all visitors to ensure complete cache bypass. Use maintenance mode to show a status page to visitors during development. On production sites the plugin shows a clear warning so you do not forget it is active. Always deactivate when finished.
Why does it deactivate optimization plugins?
Optimization plugins like Perfmatters, FlyingPress, and WP Asset CleanUp modify how CSS, JS, and other assets are loaded. During debugging, you need to see the unmodified output to identify issues. These plugins are temporarily deactivated. Reactivate them manually from the Plugins page when you are done.
What happens to my wp-config.php and .htaccess?
The plugin edits both files in place. It wraps its own changes in clearly marked blocks and comments out (never deletes) any of your settings that conflict. On deactivation it removes only its own block and restores your original lines, so your own definitions are preserved. It never keeps a copy of wp-config.php on disk, so your database credentials are never exposed.
Why does maintenance mode not show in incognito?
Version 4.0 injects .htaccess rules that disable server-level caching and sends aggressive cache-busting headers (including CDN and proxy bypass headers) to ensure the maintenance page is always served correctly.
Can I customize the maintenance page?
Yes. Use the ayudawp_anticache_maintenance_data filter to customize heading, status text, message, and retry text.
Can I add support for custom cache plugins?
Yes. Use the ayudawp_anticache_cache_plugins filter to add entries to the plugin list.
The .htaccess rules show as “N/A” – why?
Your server (nginx or Caddy) does not read .htaccess files, so the rules would have no effect and the kit does not write them. The settings panel shows an equivalent nginx snippet you can add to your server configuration and reload.
How do I purge a Varnish cache?
Enable “Purge Varnish” in the settings panel. When you flush caches, the kit detects Varnish from the response headers and sends a best-effort PURGE/BAN to your site root. It is off by default and never runs on servers without Varnish.
