Overview
Checkly is an active reliability layer built from the ground up for developers and AI agents. It reimagines testing and monitoring for a new era of software development, letting teams write, test, and version monitors as code (JS/TS, Terraform, or Pulumi) and deploy them to 20+ global locations with a single command.
Developers love Checkly because it is code-first by default and AI-native. You can go from prompt to production monitoring in seconds, using AI to generate browser checks, API monitors, and heartbeat checks. The platform integrates directly with AI coding agents like Claude Code, so your agents can own reliability—creating monitors, running tests, and responding to incidents with your favorite model.
Checkly provides a clear signal of application health across test, staging, and production environments. With multi-region monitoring, alert channels (Slack, PagerDuty), and status pages, teams can detect, communicate, and resolve issues faster.
Key Features
- AI-Native Workflow: Write and manage tests, monitors, and alerts with AI assistance; integrate with Claude Code and other AI agents to automate reliability tasks.
- Code-First Monitoring: Define monitors as JS/TS, Terraform, or Pulumi; version control and deploy with

- Global Multi-Region Testing: Deploy monitors to regions like us-east-1, eu-west-1, ap-south-1, and ap-northeast-1 for comprehensive coverage.
- Alerting & Status Pages: Configure alert channels (Slack, PagerDuty) and manage status pages to communicate incidents to stakeholders.
Use Cases
- DevOps Teams: Set up heartbeat checks for ETL pipelines with grace periods and Slack alerts to catch failures before they impact users.
- AI-Powered Development: Use Claude Code or other AI agents to automatically create URL monitors for new API routes or browser for
