The extended edition of Safe Speed Cache: the same safe, reversible page cache, plus advanced speed options, more image tools, scheduled database clean-up, CDN and purge integrations, an object-cache manager and optional Web Vitals sampling. Every option is off until you turn it on.
Read the documentation The free pluginEverything works on its own and every option has its own switch. Safe mode turns all of it off at once.
The same safe page-cache core, pre-flight checks, Safe mode, Optimize tab, Images, Database and Extras tabs, with the paid edition's additions below.
Combine CSS and JavaScript files, delay JavaScript until the first interaction, reduced stylesheets, critical CSS per page type, preload/prefetch/preconnect hints, Google Fonts hosted on your own site, font-display: swap.
Unlimited background bulk runs with pause and resume, AVIF copies where your server supports them, <picture> markup, optional Apache/LiteSpeed rules and an nginx snippet, a daily re-scan and an image sizes helper.
Daily or weekly database clean-up of only the kinds you tick and only items older than the days you set, plus OPTIMIZE TABLE on your own tables. Off until you switch it on. No undo.
Point static file addresses at the CDN address you enter. HTML only: CSS file contents and module scripts are not changed. The plugin never contacts the CDN.
Ask Cloudflare to purge the same addresses when the plugin purges. Call the purge function of Kinsta, WP Engine, SiteGround, Cloudways (Breeze) or LiteSpeed Cache, or send HTTP PURGE to your own site.
Installs a persistent object-cache drop-in for a Redis or Memcached server that you run, after a connection test, with a backup of any other drop-in. WordPress keeps working if the server goes away.
Optional, off by default: five timing numbers from real visits, stored only as daily counts, with no cookie, IP address or page address.
Every service, what is sent to it and when is listed in the documentation.
Limits you should know: multisite networks are not supported; the database clean-up has no undo and makes no backup; the CDN rewrite changes the page HTML only; the preload depends on WP-Cron.
