Playwright Test has built-in screenshot baseline comparison; Selenium WebDriver can capture screenshots, but the cited Selenium screenshot APIs do not provide that baseline-comparison workflow. For Selenium visual regression, add image-comparison logic or a separate visual-testing tool. Choose based on whether an integrated assertion or flexibility around an existing Selenium suite matters more—and plan to control rendering differences either way.
Capture is not the same as visual comparison
A screenshot is an image captured from a page or element. Visual regression testing adds two more pieces: a reference image (the baseline) and a method for deciding whether a new capture differs enough to fail a test.
Playwright Test documents both capture and comparison: its screenshot assertion can create a reference on the first run and compare later runs against it. Selenium’s official screenshot documentation shows how to capture a browsing context or element, but those cited APIs document capture rather than a built-in golden-image lifecycle. Selenium can be extended; the comparison and baseline workflow must come from additional code or tooling.
How the workflows differ
| Area | Playwright Test | Selenium WebDriver |
|---|---|---|
| Capture | Page screenshots and screenshot assertions are available. | Official examples capture the current browsing context and elements, with APIs varying by binding. |
| Baseline lifecycle | The first assertion run writes a reference image; subsequent runs compare against it. | The cited screenshot APIs document image capture, not a built-in baseline lifecycle. Add comparison logic or a separate visual-testing component. |
| Stabilization | Screenshot assertions retry until consecutive captures match. The API also documents controls for animations, caret, scale, and other screenshot behavior. | The cited APIs establish capture capability, not an equivalent built-in stabilization or dynamic-content masking workflow. |
| Difference controls | Documented controls include a pixel-difference limit and color-difference threshold. | Difference thresholds belong to the comparison layer you choose to add; they are not described by the cited screenshot APIs. |
| Environment | Baselines can vary with host OS, browser version, settings, hardware, power source, and headless mode. | Screenshot behavior can depend on browser support and active browsing context; the API documentation distinguishes conformant from non-conformant implementations. |
The Selenium distinction here is limited to the scope of its cited screenshot documentation: it demonstrates capture, not that Selenium cannot participate in visual testing.
#1 Best Overall
Write a Playwright screenshot assertion
Screenshot comparison assertions are part of the Playwright Test runner, not a general assertion available in every Playwright use case. In a Playwright Test test, the core assertion is:
await expect(page).toHaveScreenshot('landing.png');On the first run, Playwright writes the reference image. Later runs compare new captures with that reference. Review a newly generated baseline before accepting it. When an intentional UI change warrants updating references, the guide documents the --update-snapshots option; use it as a deliberate, reviewable baseline change rather than a way to silence every difference.

Control rendering noise before loosening thresholds
Playwright retries screenshot captures until two consecutive page screenshots match before checking the expectation. Its screenshot options include animation handling, caret behavior, and scale. The assertion API documents disabling animations by default. For a genuinely volatile region—such as a timestamp or rotating content—use the documented stylesheet option to hide or alter it for the capture.
Only after stabilizing the page should you consider difference tolerances such as maxDiffPixels or a color-difference threshold. A tolerance that is too strict can make harmless rendering changes noisy; one that is too generous can hide real regressions. Inspect the generated diff and tune against the UI and review process rather than treating a passing assertion as proof that every meaningful visual defect was detected.

Capture screenshots with Selenium
Selenium’s screenshot API captures an image; you then need to save, compare, and report it using your chosen language and comparison layer. The official examples include Python’s driver.save_screenshot(...) and JavaScript’s driver.takeScreenshot(). Selenium also documents element screenshots in supported bindings.
Python page capture
from selenium import webdriver
driver = webdriver.Chrome()
try:
driver.get("https://example.com")
if not driver.save_screenshot("page.png"):
raise RuntimeError("Selenium did not save the screenshot")
finally:
driver.quit()JavaScript page capture
const { Builder } = require('selenium-webdriver');
const fs = require('node:fs/promises');
(async () => {
const driver = await new Builder().forBrowser('chrome').build();
try {
await driver.get('https://example.com');
const image = await driver.takeScreenshot();
await fs.writeFile('page.png', image, 'base64');
} finally {
await driver.quit();
}
})();These examples save captures; they do not implement a baseline store, pixel diff, threshold policy, or test failure reporting. Add those pieces explicitly if your goal is regression testing, and check the binding and browser behavior you use for element capture.

Which approach fits your test suite?
- Choose Playwright Test when you want the test runner to manage reference screenshots and provide screenshot assertions and comparison controls in the same workflow.
- Keep Selenium and add comparison tooling when your suite already depends on WebDriver or its browser coverage and infrastructure. Account for the ongoing work of storing baselines, comparing images, managing tolerances, and reviewing changes.
- For either framework, standardize the rendering environment. Keep the OS, browser version, settings, and headless configuration consistent for baseline creation and comparison. Browser and platform differences can change fonts and rendering, so a single universal baseline may not be appropriate; browser- or platform-specific snapshots may be needed.
- Make baseline updates reviewable. Treat an approved UI change and an accidental visual regression differently; do not accept changed references without inspecting what changed.
Or skip the browser setup: ScreenshotNeo
If you need a clean website capture outside a Playwright or Selenium test, ScreenshotNeo is a website screenshot API and MCP server. A single GET request returns a PNG, JPEG, WebP, or PDF. For example, this cURL request captures a URL as WebP:
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpSee the ScreenshotNeo API documentation for request parameters. Cookie banners are accepted like a visitor and removed, along with supported newsletter popups and chat widgets, before capture; each step can be turned off. Bot checks, blank pages, failed loads, timeouts, and cache hits are not billed, and response headers report the page verdict and billing status. Its MCP server provides take_screenshot, get_page_info, and capture_pdf tools for Claude, Cursor, and other MCP clients. The free plan includes 1,000 screenshots per month with no card; paid plans start at $5 for 3,000 shots.

Troubleshooting screenshot tests
Playwright fails on a screenshot diff you did not expect
First check whether the baseline and test run used the same OS, browser version, settings, hardware conditions, and headless mode. Then inspect the diff for dynamic content, animation, or caret changes. Stabilize or mask only the volatile part before adjusting the pixel or color tolerance.
Playwright keeps producing changing captures
Wait for the page’s meaningful content to load and remove or control known volatile output. Screenshot assertions already retry until two consecutive page captures match; persistent variation means the page may still be changing or the environment is inconsistent.
A screenshot update makes the test pass but obscures a regression
Do not update references reflexively. Review the image difference and confirm the UI change is intended before accepting a new baseline with --update-snapshots.
Selenium saves a screenshot, but no visual test fails
Capture alone does not compare images. Verify that the test also reads the saved image, compares it with the intended baseline using an explicit threshold policy, and reports differences as a test failure. That comparison layer is separate from the screenshot APIs described in Selenium’s documentation.
Selenium screenshot output differs across browsers
Check the browser’s screenshot support and active browsing context, and keep the capture environment consistent. Selenium’s Java API describes best-effort output for non-W3C-conformant implementations, so behavior can depend on the implementation.
