Monitoring as code

Transform your development workflow with a code-based monitoring process that's programmable, fast, and dependable.


Your app’s code lives in your repository. Your monitoring should too. Create resources in a programmable way, coding them instead of configuring them.


Test your resources from your local machine or during deployment in CI, all running on Checkly’s global infrastructure.
