Checkly is a monitoring service that periodically checks the behavior of APIs and websites. It runs API checks, which verify the response code and content of HTTP requests, and browser checks, which reproduce user flows in a real browser with Playwright scripts, from multiple regions, and sends alerts on failure. Its distinguishing feature is the monitoring-as-code approach, where check definitions are kept as code in a repository and deployed via the CLI.
