WP Super Cache

Overview

WP Super Cache is a free page-cache plugin maintained by Automattic, the company behind WordPress.com and Jetpack. It was added to the WordPress.org directory in November 2007 and reports 1+ million active installations.^[8]

The plugin generates static HTML files from dynamic pages and serves them to visitors who are not logged in, have not left a comment and have not viewed a password-protected post. Its documentation states that such visitors make up the vast majority of traffic, while logged-in users and commenters receive individually cached files.^[8] It offers three delivery modes. The fastest, “Expert”, uses Apache mod_rewrite to serve supercached files without loading PHP at all; this requires editing the .htaccess file, which the documentation itself describes as risky. Simpler modes serve cached files through PHP.^[8]

WP Super Cache is deliberately narrow: it does not minify assets, generate critical CSS or delay JavaScript, so it is usually paired with a separate optimisation plugin when Core Web Vitals are a concern. It is actively maintained; release 3.1.5 on 2 November 2026 stopped requests with a malformed Host header from being cached, and 3.1.4 in September 2026 updated compatibility to WordPress 7.1.^[8]
