GTmetrix vs Screpy in 2026: Dedicated speed testing vs an all-in-one budget dashboard

GTmetrix runs a page through a real Chromium browser and returns a waterfall chart, Core Web Vitals scores, and a Lighthouse-based performance grade. It is a specialist tool: it does not crawl your site for broken links, does not track rankings, and does not watch for downtime. What it does, it does clearly enough that developers who are not performance specialists can look at a waterfall chart and immediately see which script or image is slowing the page down.

The free tier is not a stripped-down trial, it is a usable product on its own, limited mainly by test locations and the absence of scheduled monitoring. Paid plans start at $5.50 a month and add monitoring slots, more test locations, mobile device emulation, and, from the Starter tier up, API access for pulling results into a CI/CD pipeline or custom dashboard.

Where GTmetrix falls short of a tool like Screpy is scope. There is no rank tracking, no uptime monitoring, and no white-label reporting layer for agencies that want to hand a branded PDF to a client. If page speed is the only problem you are solving this month, that narrowness is a feature. If you are trying to consolidate tools, it is a gap you will need to fill elsewhere.

Screpy takes the opposite approach: instead of doing one job well, it covers auditing, rank tracking, page speed, Core Web Vitals, and uptime monitoring in a single $10-a-month plan with unlimited projects and unlimited team members. For a freelancer managing several small client sites, that is a meaningful amount of coverage for less than the price of a single GTmetrix Starter plan.

The trade-off shows up the moment you need depth in any one category. The site audit crawls fewer pages than a dedicated crawler, the rank tracker covers the basics without the granularity of a standalone tool, and there is no waterfall chart or resource-level breakdown for diagnosing exactly why a page is slow, just an overall Lighthouse-based score. Screpy is also mid-transition: the vendor has signaled a substantial platform rebuild in progress, so features you rely on today could shift.

What Screpy does not compromise on is price and packaging. Unlimited projects and team members are included on every plan, and white-label PDF reports are available from the $30 Pro tier, which is unusually low for that feature. The one hard gap is API access: there is none, on any plan, which rules Screpy out for anyone who wants to pipe data into a custom dashboard.
