Code-first workflow

Your entire monitoring workflow, defined as code in your existing code base.

Monitor your APIs

Seamlessly integrate API monitoring into your E2E testing and monitoring regimen.

Harness the Power of Playwright

Fully harness the power of Playwright to validate the reliability of your web app with Checkly’s browser checks.

Run From Your Repository

Store all monitoring resources in your Git repo, alongside your application code: just like the unit testing patterns you are familiar with.

Typescript First

Code, compose, and structure your monitoring resources using TypeScript. No YAML-engineering needed.

Code and Collaborate

Use any CI platform to collaborate with your team to code, test, and deploy E2E browser and API checks.

Code and configure your tests and monitors

Your app’s code lives in your repository. Your monitoring should too. Create resources in a programmable way: use loops, read files or add conditions. You code your monitoring infrastructure instead of configuring it.

new BrowserCheck('homepage-browser-check-1', {
  name: 'Browser Check #1',
  frequency: 10,
  regions: ['us-east-1', 'eu-west-1'],
  code: {
    entrypoint: './home.spec.js'
  }
})

new ApiCheck('product-api-check-1', {
  name: 'Product API - fetch products',
  degradedResponseTime: 10000,
  maxResponseTime: 20000,
  requests: {
    url: "https://api.acme.com/v1/products",
    method: "GET",
    assertions: [AssertionBuilder.statusCode().equals(200)]
  }
})

Run your tests during your CI/CD in our cloud

Test your future monitoring resources from your local machine or during CI deployments—all running on Checkly’s global infrastructure.
