WordPress Core Web Vitals: the free AIFORYA extension
Optimize your WordPress Core Web Vitals for free: real-user monitoring (RUM), WebP/AVIF images, minification, cache and Lighthouse audits. Free extension

Optimize your Core Web Vitals and speed up your WordPress site.
AIFORYA Page Speed measures the performance of your real visits, optimizes your images in the background and gives you a clear dashboard of your LCP, CLS, INP and TTFB. All of it locally, without heavy configuration and without a mandatory API key — and for free, with no time limit.
- Free and complete: published on WordPress.org, no crippled features.
- No quota: WebP/AVIF image optimization runs locally, with no monthly limit.
- Real measurements: Core Web Vitals tracking on your visitors, with no cookies or personal data.
Why monitor your Core Web Vitals?
Core Web Vitals (LCP, CLS, INP) are not a Google whim: they are the metrics that partly decide your ranking and, above all, the real experience of your visitors. A slow site loses readers before it is even read. The problem is that most tools measure speed in a lab, on an artificial visit — not what your real users experience.
AIFORYA Page Speed combines both approaches: Real User Monitoring captures the performance of your real visitors, and Lighthouse audits give you the detailed diagnosis of a page. Between the two, the optimization modules (images, minification, cache, local fonts) act concretely on the causes of slowness.
What the extension does
- Real User Monitoring (RUM) — measures LCP, CLS, INP, TTFB and FCP on your real visitors via the native PerformanceObserver API, with no cookies or personal data.
- Core Web Vitals dashboard — 7-day averages with color coding (good / needs improvement / poor) according to Google's thresholds.
- Image optimization queue — WebP/AVIF conversion and compression, run locally (Imagick/GD) in batches via WP-Cron, with no quota.
- CSS/JS minification and page cache — enabled in one click.
- Loading hints — preconnect, dns-prefetch, preload of custom fonts and preload of the LCP image.
- Local fonts — serve your fonts from your server with
font-display: swap. - Lighthouse audits — page audit via the Google PageSpeed Insights API (optional Google key to lift the rate limit) + score history.
- Cache purge — compatible with the main cache plugins (WP Rocket, LiteSpeed, W3 Total Cache, WP Super Cache).
- Multilingual interface — English, French, German, Spanish, Italian, Dutch.
Transparency note
Unlike a 100% local extension, AIFORYA Page Speed can communicate with two external services, in specific cases and without personal data:
- Google PageSpeed Insights — contacted only when you launch a Lighthouse audit (or during the automatic daily audit). The extension sends the public URL to audit, and your PageSpeed Insights key if you configure one. This service is provided by Google.
- AIFORYA service — contacted only if you use the Support or Reviews tabs, with your explicit consent.
Everything else — Core Web Vitals tracking, image optimization, minification, cache and loading hints — works entirely locally, with data stored only in your site's database.
