Why Checkly and not Pingdom?

Powerful E2E Checks

Runscope is great when you only want to know if your APIs are up. But it doesn’t show you the full picture - whether your UI and endpoints are working correctly.

Flexible API monitoring

Checkly provides powerful insights and tools to customize your checks. Instead of a simple ping, you can create fully fledged configurable HTTP checks to monitor APIs.

Code-first workflow

Code your monitoring on your local machine, test your preview deployments in CI, and monitor in production.

Typescript First

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

Run from your repository

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

Code and Collaborate

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

“Checkly is incredible:

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

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.

Learn more about API Checks
api.check.ts
new ApiCheck("public-stats-endpoint", {
  name: "API: Public stats",
  alertChannels: [],
  degradedResponseTime: 10000,
  maxResponseTime: 20000,
  frequency: Frequency.EVERY_30S,
  request: {
    url: "https://api.checklyhq.com/public-stats",
    method: "GET",
    followRedirects: true,
    skipSSL: false,
    assertions: [
      AssertionBuilder.statusCode().equals(200),
      AssertionBuilder.jsonBody("$.apiCheckResults").greaterThan(5000_000_000),
    ],
  },
  setupScript: {
    entrypoint: path.join(__dirname, "setup.ts"),
  },
  tearDownScript: {
    entrypoint: path.join(__dirname, "teardown.ts"),
  },
});

E2E checks with real browsers

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

Learn more about synthetic monitoring
home.spec.ts
import { expect, test } from "@playwright/test"

test(
  "wait for an element to become visible",
  async ({ page }) => {
    await page.goto("https://www.checklyhq.com/")

    const mainHeadline = page.locator("#landing h1")
    await expect(mainHeadline).toBeVisible()

    await page.screenshot({ path: "screenshot.jpg" })
  }
)

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.

A unique monitoring as code workflow

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
