GTmetrix vs SpeedCurve (2026): which should you pick?

Pick GTmetrix if

• Fits if you want a Lighthouse report with a load video for a page now and then
• Works for developers who want to start speed tests from their own code through the API

Look elsewhere if

• Tight if you watch many pages, as Lite monitors 1 and Core 3, and hourly checks start on Advanced at $24.99 a month
• Pricey if a team shares it, as seats start on Expert at $49.99 a month yearly, and white-label PDFs are Enterprise only at a quoted price
• Tight if you stay on Basic or Lite: Basic runs 2 API tests at a time against 8 for most PRO users, and Lite gets the API only as a 10-credit trial
• Watch out: API tests spend credits, a video costs 0.9 more, and credits refill daily only up to the plan's allowance
• Watch out: API reports are kept 1 month unless you pay credits for up to 24, and refunds become account credit after 14 days

Pick SpeedCurve if

• Fits if you want to see whether faster pages line up with more conversions
• Works for teams of any size, since users and teams are unlimited

Look elsewhere if

• Watch out: every URL, browser, region and scheduled run counts as a check, so testing many pages in many places adds up fast
• Not for you if you might cancel mid-year, as annual plans get no prorated refund
• Pricey if you want 13 months of data or priority support, which start at $500 a month
• Tight if you need SSO or private test agents, which need an annual plan over $12,000
• Watch out: paying by invoice needs a plan of $5,000 a year or more

GTmetrix

• Team seats start only on Expert ($49.99 a month billed yearly), and hourly monitoring on Advanced; refunds are promised for 14 days, after that only account credit.
• API tests run on credits: a Lighthouse report costs 1 credit, a video 0.9 more, and credits refill daily only up to the plan's allowance.
• Through the API, Basic accounts can run 2 tests at once, against 8 for most PRO users.
• API reports are kept 1 month unless longer retention, up to 24 months, is paid for in extra credits.

SpeedCurve

• The listed prices include a 20% annual discount, and an annual plan cancelled partway through gets no prorated refund.
• Synthetic checks count every URL, browser, region and scheduled run, so testing many pages in several places raises the cost quickly.
• 13-month data retention and priority support start at $500 a month; single sign-on and private agents need an annual plan over $12,000.
• Paying by invoice is limited to plans of $5,000 a year or more.

GTmetrix

Lighthouse speed reports

Each test produces a Lighthouse report, with older PageSpeed and YSlow reports or a metrics-only report also available through the API.

Locations, browsers and devices

Choose the test location and browser, simulate phones and tablets by screen size and pixel ratio, and throttle the connection speed.

Videos and PDF reports

Record a video and filmstrip of the page loading, and export a summary or full PDF of the report.

Page monitoring and alerts

Monitored pages are retested on a schedule, grouped with tags, and can raise performance alerts when chosen metrics cross set conditions.

REST API

Start tests, fetch reports and manage monitored pages from your own code, with an OpenAPI specification and a GTmetrix for WordPress plugin.

SpeedCurve

Real user monitoring

Measures page views from real visitors, with sampling to control cost, custom data, conversion correlation and A/B test segments.

Synthetic monitoring

Scheduled tests in several browsers and regions, with scripting for user flows, pages behind a login and private staging sites.

Performance budgets and alerts

Set budgets on RUM and synthetic metrics and get alerts by email, Slack or webhook when a page crosses one.

Core Web Vitals debugging

Breaks Core Web Vitals into subparts, finds layout shift causes, and tracks first- and third-party requests and JavaScript impact.

Competitive benchmarking

Test competitors' pages alongside your own and produce side-by-side comparison videos.

CI/CD and deploy testing

Trigger tests on each deploy through the API, the GitHub integration or CI tools such as CircleCI, and mark deployments on charts.
