Which one is for you
Pick Calibre if
- Fits if you watch lots of sites, since Starter allows unlimited sites
- Works for developers who want speed checks on each GitHub pull request
Look elsewhere if
- Watch out: monitoring stops when the monthly test allowance runs out, unless you buy packs at $60 per 5,000
- Tight if you get real traffic, as Starter's real user tracking pauses at 5,000 sessions a month
- Pricey if your team grows, at $15 a month for each seat past those included
- Watch out: cancelling deletes all of an account's data immediately and permanently
- Pricey if you pay yearly expecting a discount, as $900 is the same as 12 monthly payments
Pick PageSpeedPlus if
- Fits if you keep a short list of key pages and want an alert when one gets slow
- Works for agencies that report Core Web Vitals to clients
Look elsewhere if
- Skip it if you want to stay free, as there is no free plan and only a 14-day trial
- Tight if you watch more than 25 URLs: Basic stops there and Standard jumps to €60
- Pricey if you want API access or hourly checks, which start on Standard at €60 a month
- Watch out: prices are in euros with no annual price shown, history is 1 month on Basic, and Enterprise has no published price

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
