Compare the workflow, not a stale checklist
Product availability, feature names and plan limits change. Use the current documentation for Lemwatch and Cronitor to validate the capabilities that matter to your team.
What must the check represent: a public page, an API, or a complete authenticated journey?
Who will configure and own it: a non-technical team, developers, or both?
Which evidence do you need after an alert: request context, a script result, logs, or a customer-facing status?
This page does not treat a feature label as a permanent product fact. Confirm current coverage, implementation requirements and commercial terms with each provider before purchase.
