AppRanks verdict
Generated from live marketplace data — refreshed daily
Easy Critical CSS is a mixed-rating WordPress app with a limited review volume. Category data on the canonical marketplace listing is currently incomplete, so AppRanks falls back to platform-wide rather than category-relative comparison for this listing. 1 reviews put it in the early-traction tier — useful for early-stage stores willing to be on the leading edge. Early-traction review counts are sensitive to single launch periods or feature events, so a 30-day re-check before bigger commitments often resolves whether the trend is sustained. Paid-only pricing means evaluating fit on the marketplace listing or via the developer's documentation before installing. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical WordPress Plugin Directory listing.

How Easy Critical CSS works
Show full descriptionShow less
Easy Critical CSS is a lightweight WordPress plugin that lets you add Critical CSS to any page on your site to improve loading speed and performance.
Features:
– Easily add Critical CSS and Secondary CSS to any page
– Secondary CSS removes unused CSS rules and stylesheets, ensuring only a single optimized CSS file loads
– Supports posts, pages, archives, and taxonomy pages
– Fully compatible with caching plugins (WP Rocket, W3 Total Cache, WP Super Cache, etc.)
– Customizable settings for individual pages
– Stores Critical CSS in your choice of the database or as static files
– Optional API service (API key required) for automated Critical and Secondary CSS generation via CriticalCSS.net
– Background processing to generate CSS without blocking page loads or admin actions
Why Use Critical CSS? Critical CSS ensures above-the-fold content loads first by reducing render-blocking CSS. This helps you boost Core Web Vitals, improve page speed scores, and deliver a better experience to your visitors.
Want to try it out first? You can generate free one-off Critical CSS at CriticalCSS.net and manually apply it to your site using the plugin settings.
