Checkly
Checkly is a monitoring-as-code platform for developers tracking critical APIs and user interfaces.
What Checkly is
Checkly is a monitoring-as-code platform for developers tracking 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 simulate actions such as logins, checkouts, and form submissions, while Playwright Check Suites run complete test suites as scheduled monitors. The Checkly CLI lets users author checks in code and deploy monitors from a terminal. Listed integrations include Slack, PagerDuty, OpsGenie, Datadog, Grafana, Discord, Terraform, and Pulumi. Checkly says it is GDPR and SOC 2 Type 2 compliant, encrypts stored data end-to-end, uses HTTPS for network traffic, and encrypts database data at rest with AES256. Its monitoring runs as an external agent from the public internet without installation inside or privileged access to a customer network. The Hobby plan is free and includes 10 uptime monitors, 1,000 browser/Playwright runs, and 10,000 API runs. Starter is $24 a month; Team is $64 a month. The Hobby plan caps monthly API and Browser Check runs at 10,000 and 1,000 respectively. Checkly presents the platform to developers, SRE and platform teams, QA engineers, and engineering managers.
