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 and flushes 16+ cache plugins
- Deactivates optimization plugins that interfere with debugging (Perfmatters, FlyingPress, WP Asset CleanUp, and more)
- Clears object cache (Redis, Memcached) and OPcache
- Clears hosting-specific caches (SiteGround, Cloudflare, Kinsta)
- Prevents browser caching for administrators
Server-level cache prevention
- Automatic timestamped backup of .htaccess before any modification
- Injects .htaccess rules to disable 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
- Sends CDN/proxy bypass headers (X-Accel-Expires, Surrogate-Control)
- Automatically restores original .htaccess on plugin deactivation
Debug mode activation
- Automatic timestamped backup of wp-config.php before any modification
- Comments out conflicting definitions with visible markers instead of deleting them
- Enables WP_DEBUG, WP_DEBUG_LOG, and SCRIPT_DEBUG (errors go to wp-content/debug.log)
- Disables WordPress cache (WP_CACHE = false)
- Safely modifies wp-config.php using WordPress Filesystem API
- Restores original wp-config.php from backup on plugin deactivation (plain copy, no processing)
- Timestamped backups are kept for reference until the plugin is deleted
