PageSpeed Insights vs SpeedVitals (2026): which should you pick?

Pick PageSpeed Insights if

• Fits if you want one page's Core Web Vitals the way Google measures them
• Works for developers adding speed checks to scripts through a free API

Look elsewhere if

• Too light for watching a whole site, as it tests one URL per run with no monitoring
• Skip it if your page has little traffic, since real-user data only shows for pages with enough Chrome visits
• Watch out: lab tests run from a Google data center in North America, Europe or Asia, and scores vary from run to run
• Tight if you keep reports, as a shared link holds its snapshot for only 30 days
• Not for you if you planned to get real-user data from its API, which Google plans to drop in favour of the CrUX API

Pick SpeedVitals if

• Fits if you need to see how fast a page loads from many countries in one run
• Works for site owners and hosts chasing a slow time to first byte

Look elsewhere if

• Skip it if you want a free trial of the paid plans, as there isn't one, only an upgrade on request
• Watch out: refunds come only within 3 days of buying and only if under 20% of the plan's credits were used
• Tight if you test in bursts, since credits are counted per week, 15 a week on the free plan
• Pricey if you need the API or webhook alerts, which start at Pro, $83 a month billed yearly
• Too light for sites with real traffic on Free or Starter, as RUM stops at 5,000 page views a month

PageSpeed Insights

• Tests one URL per run, and a shared report link keeps its snapshot for only 30 days.
• Real-user data appears only for public pages with enough Chrome visits; otherwise only the lab test is shown.
• Lab tests run from a Google data center in North America, Europe or Asia, and scores vary from run to run.
• Google plans to drop real-user data from the API and points developers to the CrUX API instead.

SpeedVitals

• There is no free trial; the FAQ says the team can upgrade an account for a while on request.
• Refunds are given only within 3 days of buying and only if under 20% of the plan's credits were used.
• Test credits are counted per week, and the API and webhook alerts start at the Pro plan.

PageSpeed Insights

Real-user data from CrUX

Shows the 75th percentile of LCP, INP, CLS and FCP, plus TTFB, from real Chrome users over the past 28 days, with the share of good, middling and poor visits.

Core Web Vitals assessment

A pass or fail on LCP, INP and CLS for the page, falling back to the whole origin when the page alone has too little data.

Lighthouse lab test

Runs Lighthouse 13 on a simulated mid-range phone and on a desktop, scoring performance, accessibility, best practices and SEO from 0 to 100.

Audits and suggestions

Each category lists audits that explain what slows the page down or breaks best practice, and what to change.

Shareable reports

A link to a report keeps a snapshot of the results for up to 30 days.

PageSpeed Insights API

The v5 API returns Lighthouse results as JSON; an API key is recommended for frequent automated tests.

SpeedVitals

Global TTFB test

Batch and multi-location tests

Run up to 50 tests in one batch, or test one URL from many locations at once; the batch size goes from 10 to 50 by plan.

Scheduled monitoring and alerts

Monitoring slots re-test a URL daily on Starter down to every 3 hours on Ultimate, with alerts by email, Slack or webhook and a weekly digest.

Real-user monitoring

A script measures real visits, with 1 to 5 years of analytics history by plan; extra page views are an add-on on Pro and Ultimate.
