Before you choose
Compare free plans and trials
Check the Free plan and Free trial fields before committing. Pricing models on the list include free, freemium and paid options.
Trial terms vary by maker. Listed examples include 14-day and 30-day trials, while some tools publish a free plan instead.
Match the platform to your stack
Platform support spans web, API, Linux, self-hosted, Windows and browser extensions. Choose the access method that fits where your checks and alerts need to run.
Review platform details alongside pricing so a lower entry cost does not hide a required deployment option.
Choose the checks you need
Use the comparison fields for browser checks, API checks, transaction checks and journey checks. Browser checks suit page flows, while API checks target service endpoints.
Transaction and journey checks can represent longer user paths. Confirm that the check type matches the path you want to monitor.
Review schedule and locations
The list compares fastest schedule and monitoring locations. A shorter schedule can help surface changes sooner, while locations help reflect access from the regions that matter to your users.
Read both fields together with the platform options before choosing a monitoring setup.
Read the paid-from field carefully
Paid pricing is listed in different units, including monthly, yearly and per-user terms. Examples on the list include $0.01, $5 per month, $7 per month, $22 per user per month and $395 per year.
Pingdom lists pricing on request. Treat the paid-from figure as a starting point, not a complete estimate of your setup.
