The Checkly Pulumi provider enables declaring your monitoring setup as code using Pulumi.

Getting started

Learn how to create, configure and sync your checks by following this getting started guide.

Pulumi CLI setup

Before getting started and writing your monitoring setup in code, you have to set up Pulumi and its CLI. Create a new Pulumi account and install the Pulumi CLI.

The pulumi command should then be available in your environment.

$ pulumi
Pulumi - Modern Infrastructure as Code

To begin working with Pulumi, run the `pulumi new` command:
  $ pulumi new

This will prompt you to create a new project for your cloud and language of choice.

Create and copy a new personal access token in your Pulumi account at

Pulumi access token configuration screen showing a newly created token

Run pulumi login and provide the token.

$ pulumi login
Manage your Pulumi stacks by logging in.
Run `pulumi login --help` for alternative login options.
Enter your access token from
    or hit <ENTER> to log in using your browser:

The CLI’s whoiam command should return your username after a successful login.

$ pulumi whoami

Now you’re ready to create a new Pulumi project and start setting up your Checkly infrastructure.

Create a new Pulumi project

Create a new directory for your Pulumi project and navigate into it.

$ mkdir new-pulumi-checkly-project && cd $_

Initialize a new Pulumi project with pulumi new and choose the minimal JavaScript template (javascript).

$ pulumi new javascript
This command will walk you through creating a new Pulumi project.

Enter a value or leave blank to accept the (default), and press <ENTER>.
Press ^C at any time to quit.

project name: (new-pulumi-checkly-project)
project description: (A minimal JavaScript Pulumi program)
Created project 'new-pulumi-checkly-project'

Please enter your desired stack name.
To create a stack in an organization, use the format <org-name>/<stack-name> (e.g. `acmecorp/dev`).
stack name: (dev)
Created stack 'dev'

Your new project is ready to go! ✨

To perform an initial deployment, run 'pulumi up'

Inspect the created files by running ls and make sure that a Pulumi.yaml, package.json and index.js file are available.

$ ls
Pulumi.yaml       node_modules      package.json
index.js          package-lock.json

Define your Checkly account ID and API key

To interact with the underlying Checkly API, provide your Checkly account ID and API key by defining those in your environment.

Your account ID is accessible at

Checkly account settings showing the account ID


Create a new API key at

Checkly api key section showing a newly created API key

export CHECKLY_API_KEY=cu_xxx

Test that both values are available in your environment.



If you prefer storing your configuration alongside your Pulumi stack for easy multi-user access, use pulumi config set.

$ pulumi config set checkly:apiKey cu_xxx --secret
$ pulumi config set checkly:accountId xxx

Install the Checkly Pulumi Provider

Install the Checkly Pulumi provider (@checkly/pulumi) with yarn or npm to integrate it in your new project.

$ npm install @checkly/pulumi
$ yarn add @checkly/pulumi

Open index.js and require it on top of the file.

const checkly = require('@checkly/pulumi')

The exported checkly object provides resources such as AlertChannel, Check, and CheckGroup, enabling you to define and configure your entire Checkly monitoring setup in code.

Add the following Check definition examples to the index.js.


How to create your first API check

new checkly.Check('my-api-check', {
  name: 'Public SpaceX API',
  activated: true,
  frequency: 10,
  type: 'API',
  locations: ['eu-west-1', 'us-west-2'],
  tags: ['pulumi'],
  degradedResponseTime: 5000,
  maxResponseTime: 15000,
  request: {
    method: 'GET',
    url: '',
    assertions: [
        source: 'STATUS_CODE',
        comparison: 'EQUALS',
        target: '200',
        source: 'JSON_BODY',
        property: '$.project_name',
        comparison: 'EQUALS',
        target: 'SpaceX-API',
  useGlobalAlertSettings: true,

How to create your first Browser check

new checkly.Check('my-browser-check-pulumi', {
  name: ' Playwright check',
  activated: true,
  frequency: 10,
  type: 'BROWSER',
  script: `
  const { expect, test } = require('@playwright/test')

  test('visit page and take screenshot', async ({ page }) => {
    const response = await page.goto('')


    await page.screenshot({ path: 'screenshot.jpg' })
  locations: ['eu-west-1', 'us-west-2'],
  tags: ['pulumi'],

Creating checks and applying changes

Your index.js file should now include instructions to create one API and one Browser check.

Initialize a deployment and apply your changes by running pulumi up.

$ pulumi up

Congratulations! Head to the Checkly dashboard to see the newly created checks.

Checkly resources should be managed either through Pulumi or the Checkly UI, not both. Modifying Pulumi-managed resources via the UI, and viceversa, is likely to cause issues.
