What it is
Checkly is a monitoring-as-code platform for developers who need to monitor critical APIs and user interfaces. It offers uptime monitors for URLs, TCP, DNS, ICMP, SSL, gRPC, Traceroute, and Heartbeat. Browser Checks use headless browsers to reproduce user actions such as signing in, checking out, and submitting forms. Playwright Check Suites run scheduled test suites and support custom dependencies and shared storage state. The Checkly CLI lets users define checks in code and deploy monitors from a terminal. Listed integrations include Slack, PagerDuty, OpsGenie, Datadog, Grafana, Discord, Terraform, and Pulumi. Checkly says monitoring runs from the public internet without requiring installation inside or privileged access to a customer network. It states that it is GDPR and SOC 2 Type 2 compliant and describes encryption for stored data and database data at rest. A free Hobby plan is available; paid plans start at $24/mo. Hobby has monthly limits of 10,000 API check runs and 1,000 Browser Check runs.
