About Checkly
Checkly lets developers write monitors as code. Browser checks are Playwright scripts, and API checks test endpoints. Both are defined in TypeScript, tested locally with the Checkly CLI and deployed to run from more than 20 global locations. Terraform and Pulumi integrations support infrastructure-as-code workflows.
Alerts go to Slack, Microsoft Teams, Discord, PagerDuty and Opsgenie, and status pages are included. Recent versions add an MCP server and agent skills so AI coding agents can write and manage checks.
