Playwright vs Selenium — Full Comparison
| Feature | Playwright | Selenium |
|---|---|---|
| Developer | Microsoft | Open-source community (Selenium HQ) |
| Year Created | 2020 | 2004 |
| Protocol | Chrome DevTools Protocol (CDP) + WebSocket | W3C WebDriver Protocol (HTTP) |
| Speed | Fast (direct browser connection) | Slower (HTTP round trips) |
| Auto-Wait | Built-in — waits for elements to be ready | Manual (implicit/explicit/fluent waits) |
| Supported Browsers | Chromium, Firefox, WebKit | Chrome, Firefox, Safari, Edge, IE |
| Languages | JS, TS, Python, Java, C# | Java, Python, C#, Ruby, JS, Kotlin |
| Network Interception | Built-in (page.route()) | Requires BrowserMob Proxy or similar |
| Browser Context | Native multi-session isolation | Single WebDriver session |
| Mobile Emulation | Built-in device emulation | Via ChromeOptions (limited) |
| iFrame Handling | Easy (frameLocator()) | Complex (switchTo().frame()) |
| Shadow DOM | Supported natively | Requires JavaScript workarounds |
| Setup Complexity | Simple (npm init playwright@latest) | Complex (separate driver downloads) |
| Test Recorder | Built-in codegen | Selenium IDE (separate tool) |
| Debugging | Trace Viewer, UI Mode, Inspector | Browser console, logs |
| Screenshots/Video | Built-in | Third-party (Allure, ExtentReports) |
| Parallel Execution | Built-in workers + sharding | TestNG parallel (requires setup) |
| IE Support | No | Yes (legacy) |
| Community | Growing rapidly | Large, well-established |
Key Advantages of Playwright
▸1. Auto-waiting eliminates flakiness
TypeScript
// Playwright — just click, it waits automatically
await page.click('#submit');
// Selenium — you must manage waits
wait.until(ExpectedConditions.elementToBeClickable(By.id("submit")));
driver.findElement(By.id("submit")).click();
▸2. Network mocking built in
TypeScript
await page.route('/api/user', route =>
route.fulfill({ json: { name: 'Test User' } })
);
▸3. Multiple pages in one test
TypeScript
const page2 = await context.newPage();
await page2.goto('https://other-site.com');
When to Choose Selenium
- ✓Legacy enterprise projects already on Selenium
- ✓IE/Edge Legacy browser testing required
- ✓Team expertise already in Selenium + Java
- ✓Project uses languages Playwright doesn't support (Ruby)
