WP Spider Cache


WP Spider Cache is your friendly neighborhood caching solution for WordPress. It uses Memcached to store both objects & page output.

It’s heroic like Batcache & Super Cache, but younger, humbler, and a born web-slinger.

It comes with:

  • Support for registering multiple cache servers
  • An administration interface for viewing cache data
  • Ability to flush specific keys & groups
  • Drop-in plugins for object-cache.php & advanced-cache.php

This plugin is largely inspired by:

  • Memcached
  • Batcache
  • Super Cache
  • Johnny Cache


  • Download and install using the built in WordPress plugin installer.
  • Copy contents of drop-ins to your wp-content directory
  • Activate in the “Plugins” area of your admin by clicking the “Activate” link.
  • No further setup or configuration is necessary.

When Memcache module is not loaded with PHP I get a fatal error instead of an explaination. I use PHP 7.1 and my host doesn’t offer Memcache, only Memcached. Also files must be copied manually to wp-content.

This plugin has no settings. Zero. It Just Works. Running it on my eCommerce website and not a single problem. Faster admin, just as fast front-end as running W3 Total Cache, and I don’t need to tweak settings. Thanks @JJJ!
