Bulk PageSpeed & Core Web Vitals Checker

Bulk PageSpeed & Core Web Vitals Checker runs Google PageSpeed Insights on a list of URLs (up to 5,000 per run) and returns one clean row per page and device: performance, SEO, accessibility and best-practices scores, lab metrics (LCP, FCP, TBT, CLS, Speed Index, page weight), real-user Core Web Vitals from Chrome UX Report (LCP, INP, CLS at the 75th percentile) with a passed / failed assessment, and the top fixes with estimated savings.

Built for SEO audits, agency reporting and monitoring site speed after releases. $5 per 1,000 tests, no Google Cloud project or API key needed.

• 📱 Mobile and desktop in one run.
• 👥 Real-user field data (CrUX): page-level when the page has enough traffic, otherwise whole-site (origin) data, clearly labelled.
• ✅ Core Web Vitals pass / fail exactly like the PageSpeed Insights report.
• 🛠️ Top opportunities per page ("Reduce unused JavaScript", "Serve images in modern formats") with ms / bytes saved.
• 🔁 Backup engine: if Google's quota is busy, pages are tested on a backup Lighthouse service so your run still finishes (lab data only).
• ⚡ Parallel testing: 100 URLs in about 5 minutes.

Pricing

Pay-per-event pricing. Paid Apify plans get automatic volume discounts (Bronze, Silver, Gold).

Event	Price
PageSpeed test (pagespeed-test)	$0.005 per URL per device ($5 per 1,000)
Backup Lighthouse test (lighthouse-test)	$0.015 per URL per device, only when Google's quota is busy and Use the backup Lighthouse service is on

Turn off the backup service to never pay the higher price (tests then fail with a clear error while Google's quota is busy). You can also add your own free Google API key under Advanced.

Schedule weekly speed checks, call it from the Apify API, or connect it to Make, Zapier, n8n and Google Sheets. AI agents can call it through the Apify MCP server; one URL takes about 15-30 seconds.

FAQ

Where does the data come from? From the official Google PageSpeed Insights API (Lighthouse lab test + Chrome UX Report field data). The backup engine runs the same open-source Lighthouse on a licensed provider (DataForSEO).

Why is there no field data for my page? Chrome UX Report only covers pages and sites with enough real Chrome traffic. Small sites show cwv_assessment: no_data.

Why do scores change between runs? Lab scores vary a few points with network and server load. Field data (CrUX) is a 28-day rolling average and is stable.
