Checkly vs Prometheus Blackbox Exporter

Checkly is a monitoring-as-code platform for developers who need to monitor APIs and user interfaces. Its uptime monitor types include URL, TCP, DNS, ICMP, SSL, gRPC, Traceroute, and Heartbeat. Browser Checks use headless browsers to simulate interactions such as logins, checkouts, and form submissions. Playwright Check Suites run full test suites on a schedule and support custom dependencies and shared storage state. The Checkly CLI lets users write checks in code and deploy monitors from a terminal. Listed integrations include Slack, PagerDuty, OpsGenie, Datadog, Grafana, Discord, Terraform, and Pulumi. Checkly says its monitors run from the public internet without installation inside or privileged access to a customer network. It also states that it is GDPR compliant and SOC 2 Type 2 compliant, with end-to-end encryption for stored data, HTTPS for network traffic, and AES256 encryption for database data at rest. The Hobby plan is free; Starter is $24 a month, and Team is $64 a month. Hobby includes 10 uptime monitors, 1,000 browser/Playwright runs, and 10,000 API runs per month.
