Perfmatters
Perfmatters is a lightweight performance plugin that takes a different angle from caching: it removes bloat. It disables WordPress features and HTTP requests you do not need (emojis, embeds, extra REST calls) and, through its script manager, lets you unload specific CSS and JavaScript on the pages where they are not used, which trims the biggest cause of slow WordPress sites: unnecessary assets.

It also handles lazy loading, preloading, local Google Fonts, and CDN URL rewriting. It is intentionally light and is designed to run alongside a caching plugin rather than replace one, so a common setup is WP Rocket or LiteSpeed Cache for caching plus Perfmatters for cutting bloat.
Perfmatters rewards owners and developers willing to use its script manager to find and unload the assets a page does not need. That per-page control is its standout feature and is where much of its performance benefit comes from.
Category context: Bundles caching, code, image, and sometimes CDN optimisation into one tool or service, aimed at Core Web Vitals with minimal setup.

What is Perfmatters?
Perfmatters is a lightweight WordPress performance plugin that improves speed by removing bloat: disabling unnecessary features and requests, and letting you unload unused CSS and JavaScript on a per-page basis via its script manager. It also handles lazy loading, preloading, and local Google Fonts.
Does Perfmatters replace a caching plugin?
No. Perfmatters focuses on trimming bloat and unloading unused scripts, not on caching. It is designed to run alongside a caching plugin, so a typical stack is a cache like WP Rocket or LiteSpeed Cache plus Perfmatters for the asset-level cleanup they do not fully cover.
What is the Perfmatters script manager?
The script manager is Perfmatters' standout feature: it lists every CSS and JavaScript file a page loads and lets you disable specific ones on pages where they are not needed (for example, a contact-form script everywhere except the contact page). Unloading unused assets is one of the most effective ways to speed up a bloated WordPress site.
