ElementsBoost is a performance-optimization plugin built specifically for Elementor-powered WordPress sites. Rather than applying generic caching, it scans each individual page for the widgets, sections, scripts, styles, addon assets, and images that Elementor and its add-ons load, then removes the ones that aren't actually used on that page — a process the company says typically frees up 300-600 KB per page. Its Pro tier (Lean Elementor) adds per-page/template/post-type asset cleanup, a Safe Preview mode that lets admins test optimized pages privately before publishing changes to visitors, a Critical CSS and JS Delay suite to speed up initial rendering, a self-hosted 'MMT Image Engine' that compresses images to WebP/AVIF without per-image API fees, and before/after PageSpeed benchmark reports run from inside WordPress. A free version is also distributed on WordPress.org with basic optimization toggles and limited monthly image optimization. ElementsBoost is designed to run alongside (not replace) caching plugins such as WP Rocket, LiteSpeed Cache, FlyingPress, Cloudflare, and Autoptimize.
Key Features
Per-page Elementor asset cleanup — Removes unused Elementor/addon CSS, JS, fonts, and assets for the specific page, template, or post type being viewed.
Safe Preview — Preview optimized pages privately before the changes go live to visitors, with reversible rules.
Critical CSS & JS Delay — Inlines above-the-fold CSS and delays non-critical scripts (chat widgets, analytics, embeds) to speed up initial rendering.
MMT Image Engine — Self-hosted WebP/AVIF image compression with no external API fees, using server binaries, Imagick, or GD.
PageSpeed Benchmarking — Runs before/after PageSpeed tests from inside the WordPress dashboard to measure real performance gains.
Pros & Cons
Pros
Per-page asset cleanup targets only the CSS/JS actually used on that page, rather than a blanket site-wide rule
Safe Preview lets admins verify optimized pages privately before changes go live to visitors, reducing the risk of breaking a design
Self-hosted MMT image engine avoids recurring per-image API fees for WebP/AVIF compression
Designed to complement (not conflict with) popular caching plugins like WP Rocket and LiteSpeed Cache
14-day money-back guarantee and a free WordPress.org version to try before buying Pro
Cons
Elementor-specific — not useful for WordPress sites built with other page builders or themes
Feature/documentation pages beyond the homepage (e.g. /features/) return 404s, making it hard to evaluate the product without buying
No public information on founding date, team size, or company location
All paid plans include identical features and differ only by site count, so smaller agencies may pay for capacity they don't need
Frequently Asked Questions
Will ElementsBoost Pro work with WP Rocket, LiteSpeed Cache, or FlyingPress?
Yes. ElementsBoost Pro removes Elementor bloat before your caching plugin optimizes delivery, so both work best used together in sequence.
Will it break my Elementor design?
Safe Preview lets you test optimized pages privately before applying changes to visitors, and all optimization rules are reversible.
What is the difference between Free and Pro?
Free handles basic cleanup. Pro adds per-page asset removal, Safe Preview, Deep Scan, Critical CSS, JS Delay, PageSpeed benchmarks, unlimited rules, and image optimization.
How does image optimization work without monthly API fees?
The MMT Image Engine processes images on your own server using compression methods like server binaries, Imagick, or GD, so there are no external paid APIs involved.
Which pricing plan should I choose?
Plan selection depends only on site count — all plans include identical Pro features. Personal covers 1 site, Business covers 5 sites, and Agency covers 20 sites.
What happens when my license expires?
Existing settings and optimized assets remain in place. An active license provides updates, new releases, and priority support, and purchases include a 14-day money-back guarantee.
