About Checkly
Checkly provides a comprehensive monitoring-as-code platform designed for modern development workflows. It allows teams to define, test, and deploy API and synthetic monitoring checks directly from their codebase using tools like Terraform and a CLI. The platform specializes in end-to-end testing with Playwright, enabling the simulation of complex user journeys like sign-ups and checkout flows. Key features include uptime monitoring, detailed alerting integrations with tools like Slack and Opsgenie, public status pages, and dashboards. Checkly helps developers catch issues before they impact users, ensuring application reliability and performance.
