Static selectors break with code changes and can't prove that a site "looks good". Is that button really missing or was the id changed? Is the site responsive on mobile? Is the correct image showing? These kinds of tests are impossible to validate with selectors alone and take a lot of time to test manually. GoodLooks.ai lets you visually validate your web pages with natural language prompts instead of selectors.

Note that these examples use a demo key that gets rotated weekly; you'll want to create your own API KEY.

const { test, expect } = require("@playwright/test");
const goodlooks = require("goodlooks");
goodlooks.configure("zpka_c0d0539ada014283bc974f0fd55835ea_2b745cbf");

test("framer", async ({ page }) => {
await page.goto("https://framer.com/");
await page.waitForTimeout(5000);
await expect(page).goodlooks("A request to enable cookies shows up");
}); |

const { test, expect, devices } = require("@playwright/test");
const goodlooks = require("goodlooks");
goodlooks.configure("zpka_c0d0539ada014283bc974f0fd55835ea_2b745cbf");

test("is mobile responsive", async ({ page }) => {
page.setViewportSize(devices["iPhone X"].viewport);
await page.goto("https://cnn.com/");
await expect(page).goodlooks("should be mobile responsive");
}); |
| Explanation | |
| ✅ PASS. The page appears to be displayed in a mobile-responsive layout. The content is aligned correctly within the confines of a narrow screen typical of mobile devices. The text is legible, the menu collapses into a hamburger icon, and the image is scaled to fit the screen width, indicating that the design adapts to a mobile resolution. | |

Install via NPM.
npm install goodlooks
Use in Playwright tests!
const { test, expect, devices } = require("@playwright/test");
const goodlooks = require("goodlooks");
goodlooks.configure("zpka_c0d0539ada014283bc974f0fd55835ea_2b745cbf");
expect.extend(goodlooks);Run your playwright tests in UI mode:
npx playwright test --ui
- Check the log to see the time frame where the
goodlookscheck is called. Hover over that. - A red highlight will appear in the Playwright UI, showing you the GUI state when the screenshot was taken
- You can also see the debug logs within the Console or Error tabs.
Only the visible part of the page is checked, not the full page. You must scroll to check other page parts.
The AI is great at identifying what is in an image, but it's not great at identifying where those things are in relation to other things. For example, don't ask GoodLooks to count items to validate their position on the screen.
