Synthetic monitoring built for developers

Continuously monitor your website for faster detection of downtime, reduced performance, or functional correctness - right from your IDE. With Checkly, you can quickly configure your entire monitoring workflow, from uptime and end-to-end checks, to alert configurations and dashboards, using Playwright, Terraform, or our CLI.

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" })
  }
)
