About Checkly

Checkly is a commercial monitoring platform for developers and platform teams. Its core idea is monitoring as code: checks are written in TypeScript, stored in the application repository and deployed alongside the app, and browser checks reuse Playwright scripts so that end-to-end tests can become production monitors.

The product covers uptime monitoring, heartbeat monitoring for cron jobs and backups that stop without notice, synthetic monitoring that simulates real user interactions, testing with an AI-powered reporter, status pages, contextual alerts, AI root cause analysis and OpenTelemetry tracing. Use cases include watching login, checkout and signup flows, validating API endpoints and promoting tagged tests from CI to scheduled checks. The vendor publishes comparisons with Datadog, New Relic, Pingdom and Catchpoint. Checkly is proprietary and vendor-hosted. It has a free start, a demo option, API documentation and a pricing page.
