PageSpeed Insights Alternative

What is PageSpeed Insights?

Google PageSpeed Insights (PSI) is Google's free web tool that runs a single Lighthouse audit on a URL and surfaces Core Web Vitals from the CrUX field dataset. It's the canonical reference for Google's own page-perf grading. Where it falls short for ongoing perf work: PSI is a one-off snapshot. There's no scheduling, no history, no alerting, no team workflow, no multi-page batch runs, no script-driven user flows, no load testing: once you click the button, you get a result and that's it. The CrUX overlay is helpful but lags by 28 days and only covers high-traffic origins.

When PSI is the right pick

• You need a one-off score for a single URL before/after a deploy.
• You want the canonical Google scoring (the same Lighthouse run that backs CWV for ranking signals).
• You don't need history, alerting, or scheduled runs.

Where PSI leaves gaps

• No scheduling. Every audit is manual. Want a daily snapshot? You're scripting around the public API yourself.
• No history. PSI shows you today's number, no chart of last week, last month, last quarter.
• No alerting. Score drops 20 points overnight? You only notice if you happen to re-run it.
• Single-URL only. Auditing 50 product pages? 50 separate PSI runs.
• No load testing. PSI measures one user's experience; it can't simulate 500 concurrent visitors.
• CrUX lag. Field data is 28-day-trailing, too slow to validate a fix you shipped yesterday.

LoadFocus vs. PageSpeed Insights: comparison

When LoadFocus is the right pick

• You want scheduled audits running automatically, not manual clicks.
• You need history to prove a regression or a fix.
• You want alerts when a key page degrades.
• You audit multiple pages regularly (a site, not just a homepage).
• You want load testing too, not just single-user audits.

Migrating from PSI

1. List the URLs you care about: typically homepage + top 5-20 landing pages.
2. Configure scheduled Lighthouse runs in LoadFocus (daily for high-traffic pages, weekly for the rest).
3. Set alert thresholds: e.g. notify if LCP > 2.5s or performance score drops by >10 points.
4. Keep PSI bookmarked for one-off sanity checks, they share the Lighthouse engine, so results align.
5. For CWV field data, LoadFocus can also surface CrUX where available, pair lab + field for the full picture.

FAQ: LoadFocus vs PageSpeed Insights

Does LoadFocus use the same Lighthouse engine as PSI?

Yes, both run Google's open-source Lighthouse. The scores will not match exactly: they move with the Lighthouse version, the test hardware, throttling and location, and PSI runs from the nearest of four Google locations. Compare a page with itself over time in one tool rather than across the two.

Can LoadFocus replace PageSpeed Insights for SEO work?

For ongoing tracking, yes. For a single SEO audit submission to Google, PSI is fine, but for week-over-week tracking of your CWV improvements, LoadFocus is the workflow tool.

Is LoadFocus free?

Yes, there's a permanent free tier. Paid plans start at $39/mo ($29/mo billed yearly) for scheduled runs at scale.

Does LoadFocus pull CrUX field data?

Where available. LoadFocus surfaces CrUX-origin data on dashboard cards. For URLs without CrUX coverage (low-traffic), only lab data is available, same as PSI.

Can LoadFocus run from multiple locations?

Yes, pick the test-from region (US/EU/APAC). PSI runs from a single Google datacenter.

Why use both?

Many teams keep PSI for ad-hoc audits + share-with-stakeholders single-URL links, while LoadFocus carries the scheduled/historical workflow. They complement.
