About Checkly

Checkly is an application reliability platform that unifies synthetic monitoring, testing, and observability into a developer-friendly workflow. It pioneered the Monitoring as Code approach, allowing teams to define and manage checks directly from their IDE. The platform offers browser checks powered by Playwright, API monitoring, uptime monitoring from global locations, and built-in status pages for transparent incident communication. Checkly supports private locations, visual regression testing, and integrates seamlessly into CI/CD pipelines.
