Why do engineers choose Checkly over Runscope?

Monitoring as Code

Create, configure, and deploy your monitors using code stored in a repository for easier tracking, improved collaboration, and increased scalability.

Powerful End-to-End API Testing

Use Playwright and OpenAPI to easily build complex, multi-step API tests that you can reuse to monitor services in production.

Unify Monitoring & Observability

Reuse tests as monitors, get full-stack traces when things go wrong, automatically update status pages, and more with the world's first unified reliability platform.

“Checkly is incredible:

It combines Pingdom, Ghost Inspector and Assertible all in the same app, and the insights are much more detailed. ”

SVP Product, Vercel

Flexible API Checks

Monitor your API for performance & correctness, run custom JavaScript before and after your check with setup & teardown scripts, and create checks with our monitoring as code workflow.

End to end monitoring on real browsers

Code your headless checks and use distributed browsers to test and monitor your sites with the Playwright testing framework.

Global Coverage

Get a clear picture of how your services perform for all your users worldwide. Run your checks from over twenty data center locations spread over the Americas, EMEA, Asia Pacific, and Africa.

Monitoring as Code: The Scalable Way To Ensure Application Reliability

Unite E2E and API testing and monitoring in one developer-focused monitoring as code (MaC) workflow.

Learn about monitoring as code

  1. Code all your resources

    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)]
  }
})

  2. Test locally and in CI/CD

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

    $ 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

  3. Deploy with confidence

    Deploy, lifecycle, and scale your end-to-end testing and monitoring solution from the command line alongside your application deployments.

    $ npx checkly deploy --preview

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

$ npx checkly deploy
