WebsiteFix One-Click Performance Optimizer is a free WordPress plugin that disables seven listed performance-related behaviors with a single click. It is described as reversible and hoster-aware, and it is built for WordPress sites running on WordPress 5.9+ and PHP 7.4+.
The plugin groups its functions into seven snippets shown on the WordPress tools page. These snippets throttle the Heartbeat API, disable XML-RPC and pingbacks, remove emoji polyfill scripts and oEmbed auto-discovery routes, strip query strings from static asset URLs, block author enumeration, remove WordPress version signals from the frontend, and remove jQuery-Migrate from the frontend while leaving it active in the admin area. The page also says each snippet is isolated and can be enabled or disabled individually, and that turning one off restores WordPress default behavior.
WebsiteFix says the snippets are aware of active protection or optimization plugins and will not interfere when Jetpack, Wordfence, Sucuri, WP Rocket, or Heartbeat Control is active. It also offers a read-only Health Check for diagnosing Heartbeat frequency, database size, and PHP memory before choosing which optimizations to apply. Installation is shown through the standard WordPress plugin process, after which the tools page presents the seven snippets with descriptions and activation buttons.
The plugin is distributed as open source under GPL v2. The page also identifies website-fix.com as the maintainer and notes that the plugin is available on WordPress.org.
