Conversion Gems editorial verdict
Free (Lite); Pro from $49/yr (1 site)
Features8/10
8 - deep conditional unloading, async/defer, responsive rules, test mode, and hardcoded asset management cover virtually every front-end asset scenario.
Value8/10
8 - free Lite tier plus $49/yr Pro entry is highly competitive for the depth of control delivered; renewal discount adds further value.
Ease of use6/10
6 - UI is clean with one-click toggles, but safe use requires technical knowledge and per-page testing; misconfiguration risk is real.
Ecosystem7/10
7 - works alongside all major caching plugins and page builders but does not replace them; no native CDN or caching layer.
Support7/10
7 - priority support and active changelog on Pro; 30-day money-back guarantee; community support for Lite via WordPress.org forums.
What it really is

Asset CleanUp Pro — WordPress plugin that selectively unloads CSS/JS files per page to eliminate front-end bloat.

Our take

A precision WordPress performance tool that lets you conditionally unload unused CSS and JavaScript on a page-by-page, post-type, or taxonomy basis — filling a gap that generic caching plugins leave open. The DB marks this as 'paid' only, but a functional free Lite version exists on WordPress.org, making the correct classification freemium. Pro unlocks async/defer JS, responsive loading rules, taxonomy/archive page control, and priority support.

Why we rate it

Fills the exact gap caching and minification plugins miss: conditional, per-page removal of assets that have no business loading on a given URL. Test mode means you can experiment without taking down your site.

The catch

No built-in caching — must pair with WP Rocket, LiteSpeed Cache, or similar. Misconfigured unload rules can break themes and plugins, so every change requires careful page-by-page verification.

Best for
WordPress sites with 10+ plugins loading unnecessary global assets
Developers targeting Core Web Vitals improvements (LCP, render-blocking resources)
Agencies managing performance across multiple client sites
Not good for
Non-WordPress platforms
Site owners who need an all-in-one caching + performance stack in a single plugin
Beginners with no tolerance for trial-and-error asset configuration
Friction report
Time to value
Moderate — installation is instant, but safely identifying and unloading the right assets per page requires methodical testing across page types.
Scale breakpoint
Audit effort scales steeply with site complexity; large sites with many unique templates require page-by-page review. Unlimited license ($149/yr) needed for agency-wide deployment.
Walled garden
Low — asset rules are stored in WordPress and can be exported; no proprietary cloud dependency or lock-in.
