I spent three years writing Selenium tests. I learned to love it — the explicit waits, the page object pattern, the way it forced you to think about browser state. Then I moved to a project using Playwright and after two weeks, I never opened a Selenium file again.
Here's an honest breakdown of why.
The Problem with Selenium (in 2026)
Selenium isn't bad. It's battle-tested, it has a massive ecosystem, and every QA engineer on the planet knows it. But it has a fundamental design problem: it was built for a different web.
The modern web is async. SPAs, React hydration, lazy loading, websockets — Selenium's synchronous mental model fights against all of this. You end up writing code like:
WebDriverWait(driver, 10).until(
EC.element_to_be_clickable((By.CSS_SELECTOR, "#submit-btn"))
)
You get used to it. But you're spending mental energy on waiting instead of testing.
What Playwright Does Differently
Playwright's core insight is simple: auto-waiting should be the default, not the exception.
When you call page.click('#submit-btn'), Playwright automatically waits for the element to be:
- Attached to the DOM
- Visible
- Stable (not animating)
- Enabled
- Receiving pointer events
All of that, for free, on every action. No WebDriverWait. No explicit sleeps. No time.sleep(2) hacks.
// This just works — no waits needed
await page.click('#submit-btn');
await expect(page.locator('.success-message')).toBeVisible();
The Features That Actually Matter
1. Parallel execution is a first-class citizen
Selenium parallelism usually means Selenium Grid, Docker, or some CI magic that inevitably breaks. In Playwright, it's built right into the test runner:
// playwright.config.ts
export default defineConfig({
workers: 4, // run 4 tests in parallel
fullyParallel: true,
});
I cut our CI pipeline from 18 minutes to 5 minutes on the same machine just by flipping this switch.
2. Network interception is trivial
Mocking APIs in Selenium requires a proxy (like BrowserMob). In Playwright, it's native:
await page.route('**/api/products', route =>
route.fulfill({ json: { products: mockData } })
);
This changed how I write tests. Instead of depending on a flaky live backend, I mock the API layer and test the UI in complete isolation.
3. Screenshots and video on failure — zero config
// playwright.config.ts
use: {
screenshot: 'only-on-failure',
video: 'retain-on-failure',
}
When a test fails in CI, I get a full video of exactly what happened. It's a game changer for debugging flaky tests.
4. The codegen tool

Playwright opens a browser and records your interactions as test code. It isn't perfect, but it's an incredible starting point for new testers to learn the API.
What Selenium Still Wins At
Cross-company standardization. If you're in a large enterprise where 50 teams use Selenium, you can't just switch overnight. The ecosystem around Selenium — reporting tools, CI integrations, talent familiarity — is still larger.
Mobile testing. Selenium + Appium is the standard for native mobile app testing. Playwright is purely browser-centric.
Legacy browser support. Need to test IE11? Selenium is your only option (and you have my condolences).
Should You Switch?
If you're starting a new project: yes, start with Playwright. The developer experience is objectively better.
If you have an existing Selenium suite: migrate gradually. Start with new test files in Playwright, and move old ones over when they need significant rework anyway.
If you're a QA engineer learning automation: learn Playwright first. Selenium is worth understanding conceptually, but Playwright is where the industry's heading.
The Bottom Line
Playwright is what Selenium would be if it were designed today. It respects the async nature of the web, it has sensible defaults, and it makes the happy path easy and the hard path possible.
Three years of Selenium taught me what to test. Two weeks of Playwright taught me how much time I'd been wasting on how to test.
