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

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

Pick WebPageTest if

• Fits if you need to see how a page loads in a given browser from a given city
• Works for checking a fix's effect side by side before you change the site, on Pro

Look elsewhere if

• Watch out: every page load counts as a run, so 5 runs with repeat views use 10 of your 150
• Tight if you stay on Starter, with 3 runs per test and no scheduled tests, alerts, API or Experiments
• Not for you if you want to try Pro first, as there's no free trial
• Too light for bigger teams, as a Pro account holds up to 5 members

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.

WebPageTest

• Every page load counts as a test run: 5 runs with first and repeat views use 10 of the monthly allowance.
• Starter allows 150 runs a month and 3 runs per test; scheduled tests, alerts, the API and Experiments need Pro.
• There is no free trial of Pro, and a Pro account holds up to 5 team members.
• The webpagetest.org site answered with a bot check; prices were read on LogicMonitor's WebPageTest pricing page.
