Monitoring reinvented for engineering teams

Monitoring as Code (MaC) enables application, site reliability, and quality engineers to create, configure, and collaborate over their entire reliability workflow straight from their IDE.

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 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 entire monitoring workflow

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

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)]
  }
})

Test your app and services in your CI/CD

Run UI and API tests on Checkly during CI/CD to catch bugs and performance errors before changes even hit production.

$ npx checkly test

Running 2 checks in eu-west-1.

src/api/__checks__/product-api.check.ts
   ✔ Product API - fetch products (65ms)

src/__checks__/homepage.check.ts
   ✔ Homepage (7s)

2 passed, 2 total

Deploy tests as real-time monitors for complete confidence

Once your tests pass and your application is deployed, Checkly runs your tests and uptime monitors at a high-frequency across our global infrastructure to continuously detect errors or performance issues that affect customers in production.

$ npx checkly deploy --preview

Create: 
    BrowserCheck: homepage-browser-check-1
    ApiCheck: product-api-check-1

$ npx checkly deploy
