PageSpeed Insights is a quick way to check how one page loads. It runs Lighthouse and shows lab data plus real-user stats from Chrome. For a free speed check with no login, it is hard to beat.

But PSI only checks one page at a time. It covers speed plus basic SEO and accessibility hints. It does not save your results, track changes, or let you share a report. SiteCurl fills those gaps with auto scans, score history, and links you can share.

If you need to check speed on one page right now, PSI works. If you run many sites and need checks across seven areas, SiteCurl is built for that.

Key differences

Multi-page monitoring

SiteCurl

Scans up to 100 pages per site on a weekly or monthly schedule. No need to test each page by hand. Issues across your full site show up in one report.

PageSpeed Insights

One page at a time, no saved results. You have to re-test manually and compare screenshots.

Seven audit types

SiteCurl

SEO, speed, security, accessibility, technical health, uptime, and AI readiness in one scan. That is 91 checks per scan.

PageSpeed Insights

Mainly speed and Core Web Vitals. Basic SEO and accessibility hints from Lighthouse, but no security, uptime, or AI readiness.

Score tracking

SiteCurl

Stores past scores so you can see trends. Get email alerts when a score drops. Know if your fixes are working over time.

PageSpeed Insights

Each test is a fresh snapshot. No history, no alerts, no way to track progress.

Shareable reports

SiteCurl

One-click share links, PDF export, and custom branding. Clients read reports without needing a login or technical background.

PageSpeed Insights

Results display in the browser. You can copy a URL but there is no formatted report or export option.

PageSpeed Insights is a fast, free way to test one page. It gives you Lighthouse scores and real-user data from Chrome. For quick speed checks, it does the job well.

SiteCurl is built for teams who need more than speed. It checks seven areas, scans multiple pages, and tracks scores over time. If you manage sites for clients and need shareable reports, SiteCurl handles that without extra work.

Many teams use PSI for quick one-off checks and SiteCurl for everything else. PSI tells you how one page loads today. SiteCurl tells you how your whole site is doing over time.

Frequently asked questions

Is PageSpeed Insights better for speed testing?

PSI provides Core Web Vitals and real-user field data from Chrome. SiteCurl checks 11 server-side speed factors. PSI goes deeper on speed per page. SiteCurl goes wider across pages and categories.

Does SiteCurl use Lighthouse?

Not in PSI itself. You would need to re-test manually and track results in a spreadsheet. SiteCurl saves scores automatically after each scan and shows trends.
