Checkly

Checkly runs automated checks and uptime monitors against your applications. You define the checks in code and deploy them with a command-line tool.

Checkly lets developers write browser checks with Playwright and monitors for URLs and API routes. Checks run on a schedule from many global locations, and your team gets alerted when one fails. Heartbeat checks cover scheduled jobs such as nightly data pipelines. Status pages are available for sharing health with users.

• Playwright browser checks for key user flows
• Checks run from 20+ global locations
• Checks written in JavaScript or TypeScript, Terraform or Pulumi
• Heartbeat checks for scheduled jobs
• Alerts and status pages

Engineering teams that keep their code in version control and want monitoring to live next to it. Teams that use AI coding agents may use it to write and manage their checks.

You can start for free, and paid plans are also available. The command-line tool is installed with npx and deploys checks to Checkly's cloud. Monitoring runs from Checkly's locations, so you should confirm that they match where your users are.
