The modern Runscope alternative for developers

Checkly is built for developers and DevOps teams using a modern tool stack.

acme.check.tsnew 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",

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.

api.check.tsnew 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"),
  },
});

home.spec.tsimport { 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" })
  }
)

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)]
  }
})

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.
