GTmetrix is a solid tool for testing page speed. You enter a URL, wait for the result, and get a waterfall chart with Core Web Vitals data. But speed is just one piece of site health. If you also care about SEO, security, or accessibility, you need a second tool. Or you can use SiteCurl and cover all seven areas in one scan.

SiteCurl also scans multiple pages per site. GTmetrix tests one URL at a time. If you manage five sites with ten pages each, that is 50 manual tests in GTmetrix vs one scheduled scan in SiteCurl.

Reports in SiteCurl are built for sharing. Each one has a link that works without a login. GTmetrix reports live on their dashboard and need a paid plan to share. If you send reports to clients, SiteCurl saves you that extra step.

GTmetrix is best for deep speed testing on one page at a time. If you need Core Web Vitals and waterfall data, it does that well. SiteCurl is built for teams who want speed checks as part of a broader audit across many pages.

If speed is your only concern, GTmetrix gives you more detail per page. If you also need SEO, security, and accessibility, SiteCurl covers all of that in one scan with reports ready to share.

Many teams use GTmetrix for one-off speed deep dives and SiteCurl for ongoing multi-category monitoring. The two tools work well side by side.

Frequently asked questions

Is GTmetrix better for speed testing?

GTmetrix provides deeper speed data per page, including Core Web Vitals and waterfall charts. SiteCurl checks 11 speed factors as part of a broader audit. If speed is your only focus, GTmetrix goes deeper. If you need a full picture, SiteCurl covers more ground.

Does SiteCurl measure Core Web Vitals?

SiteCurl does not measure Core Web Vitals. It checks page size, compression, script count, image loading, and other server-side speed factors. For lab-based CWV data, use GTmetrix or Lighthouse.

Can I use both tools together?

Yes. GTmetrix is great for deep speed tests on specific pages. SiteCurl handles ongoing multi-category monitoring across all your sites. Many teams use both.

How does pricing compare?

GTmetrix has a limited free tier. Paid plans start at about $13/mo. SiteCurl Pro is $29/mo with seven audit types and multi-page scanning. Both offer trial periods.

Does GTmetrix check security or SEO?

No. GTmetrix focuses on page speed and Core Web Vitals. For security, SEO, accessibility, and other checks, you need a separate tool or SiteCurl.

Can I share SiteCurl reports with clients?

Yes. Every report has a shareable link that works without a login. You can also export to PDF or CSV. Studio plans include your own branding on the reports.
