Perfmatters
Lightweight WordPress plugin that reduces bloat and boosts speed using script control and performance tweaks.
Our take: Perfmatters fills a gap that caching plugins leave open: granular, per-page control over which scripts and styles actually load.
The sharpest WordPress performance scalpel available for under $30/yr — a must-have complement to any caching stack.

Our takePerfmatters fills a gap that caching plugins leave open: granular, per-page control over which scripts and styles actually load.
Why we rate itAt under $30/yr for a single site, Perfmatters delivers feature depth that rivals plugins costing several times more.
The catchNo built-in caching or CDN — you must pair it with a dedicated caching plugin.
Best / not good for
- WordPress developers tuning Core Web Vitals on client sites
- Agencies managing 3+ sites who want unified script control at the Business/Unlimited tiers
- WooCommerce stores reducing checkout-page script bloat for conversion gains
- Site owners wanting an all-in-one caching + performance solution in a single plugin
- Non-WordPress platforms — this is WordPress-only
- Beginners with no testing workflow, as misconfigured toggles can break pages
Friction report
Trade-offs to know before signing up.
- Time to valueFast: install, activate, and toggle obvious bloat (emojis, embeds, REST API exposure) in under 10 minutes. Script Manager tuning takes longer but is optional.
- Scale breakpointMinimal — the Unlimited license removes per-site cost friction. Managing Script Manager rules across dozens of sites can become time-consuming without a documented process.
- Walled gardenLow: Perfmatters writes no proprietary data structures; disabling it immediately returns the site to its pre-plugin state.
