Prices checked October 30, 2026Each row is the cheapest public package from that vendor that covers this plan's limits, not its entry plan, billed monthly where the vendor offers it. Piwik PRO Enterprise and JetOctopus bill annually only, so those rows show the annual price per month. On Standard and Advanced, JetOctopus and Sitechecker show their largest public plan, since larger volumes are quote-only. UptimeRobot and Piwik PRO price in euros, converted at the ECB rate of 1.1172 (October 30, 2026). Yearly savings are the monthly difference times 12. All prices exclude VAT.
