Product overview
Checkly is a monitoring and observability platform designed to bridge the gap between synthetic monitoring and automated testing. It primarily focuses on API monitoring and E2E (end-to-end) testing, allowing development teams to verify the performance and correctness of their web applications in real-time. By utilizing a "monitoring as code" workflow, Checkly enables engineers to manage their monitoring suites using familiar tools like JavaScript, TypeScript, and Playwright or Puppeteer. This approach allows tests to be version-controlled and integrated directly into continuous integration and continuous deployment (CI/CD) pipelines. The platform executes checks from global locations to ensure that services are reachable and functional for users worldwide. Beyond simple uptime pings, Checkly provides detailed insights into failed assertions, including screenshots, video recordings of failed sessions, and trace files to assist with debugging. It integrates with common alerting and incident management tools such as Slack, PagerDuty, and Opsgenie, ensuring that stakeholders are notified immediately when a performance regression or outage occurs. By unifying testing and production monitoring, it helps teams catch issues before they impact the end-user experience.
