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 is an honest breakdown of why.
The Problem with Selenium (in 2025)
Selenium is not bad. It is 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 are spending mental energy on waiting instead of testing.
What Playwright Does Differently
Playwright's core insight is that 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. In Playwright, it is built 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.
2. Network interception is trivial
Mocking APIs in Selenium requires a proxy (like BrowserMob). In Playwright:
await page.route('**/api/products', route =>
route.fulfill({ json: { products: mockData } })
);
This changed how I write tests. Instead of depending on a live backend, I mock the API layer and test the UI in 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. Game changer for debugging flaky tests.
4. The codegen tool

Playwright opens a browser and records your interactions as test code. It is not perfect, but it is an incredible starting point for new testers.
What Selenium Still Wins At
Cross-company standardization. If you are in a large enterprise where 50 teams use Selenium, you can not just switch. 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 browser-only.
Legacy browser support. Need to test IE11? Selenium is your only option (and my condolences).
Should You Switch?
If you are 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 are a QA engineer learning automation: learn Playwright first. Selenium is worth understanding conceptually, but Playwright is where the industry is 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 had been wasting on how to test.
