Checkly is a uptime & monitoring tool for Developers, offered as freemium ($24/mo). Founded in Germany in 2018.
About Checkly
Checkly is a synthetic monitoring platform from Berlin built on the idea of monitoring as code. Engineering teams write API checks and browser checks in JavaScript or TypeScript, using Playwright for browser flows, keep them in the same repository as the application, and deploy them with the Checkly CLI or Terraform.
The same checks run in CI against preview deployments before a release and then continuously from global locations after it, so a broken login or checkout flow is caught by a test first and by monitoring second. Assertions, retries, alert channels such as Slack, PagerDuty and email, multistep API checks and heartbeat monitors are available, and traces connect a failed check to backend spans through OpenTelemetry. A free Hobby plan includes a monthly quota of API and browser check runs; Starter and Team plans add runs, locations and collaboration, and Enterprise adds SSO and private locations inside your own network.
Checkly fits teams that already write Playwright tests and want one source of truth for end-to-end testing and production monitoring. It requires coding and is not a full observability suite, so it is a poor fit for non-technical teams who only want uptime pings. Better Stack and UptimeRobot are simpler for basic uptime and status pages, Datadog Synthetics suits teams already on Datadog, and Grafana Cloud offers synthetic monitoring inside its own stack.
