Answer
Playwright vs Cypress
| Feature | Playwright | Cypress |
|---|---|---|
| Browser Support | Chromium, Firefox, WebKit (Safari) | Chrome, Edge, Firefox (no Safari) |
| Language Support | JS, TS, Python, Java, C# | JavaScript / TypeScript only |
| Architecture | Out-of-process (controls browser externally) | In-process (runs inside browser) |
| Multi-Tab Support | Yes — native | No — cannot open new tabs |
| iFrame Support | Yes — frameLocator() | Limited |
| Network Stubbing | page.route() — intercepts all requests | cy.intercept() — similar |
| Speed | Fast | Fast (but can be slower on CI) |
| Mobile Testing | Device emulation, limited real device | Limited emulation |
| Component Testing | Yes (experimental) | Yes (mature) |
| API Testing | Yes — request fixture | Yes — cy.request() |
| Parallelism | Workers + sharding (built-in) | Requires Cypress Cloud (paid) |
| Debugging | Trace Viewer, UI Mode, Inspector | Time-travel debugging in browser |
| Community | Growing fast | Large, established |
| Pricing | Free (open source) | Free (open) + Cypress Cloud (paid) |
| Cross-Origin | No restriction | Same-origin restrictions apply |
Architecture Difference
Cypress runs JavaScript inside the browser — it has direct DOM access but cannot control multiple tabs or cross-origin requests without workarounds.
Playwright runs outside the browser and controls it via protocol — giving full control over network, multiple pages, downloads, and browser contexts.
Code Style Comparison
Playwright:
TypeScript
// Async/await — standard JavaScript
test('login', async ({ page }) => {
await page.goto('/login');
await page.fill('#email', 'user@test.com');
await page.click('#submit');
await expect(page).toHaveURL('/dashboard');
});
Cypress:
JavaScript
// Command chaining — Cypress-specific syntax
it('login', () => {
cy.visit('/login');
cy.get('#email').type('user@test.com');
cy.get('#submit').click();
cy.url().should('include', '/dashboard');
});
When to Choose Playwright
- ✓Safari/WebKit testing is required
- ✓Multi-tab/multi-window testing needed
- ✓Non-JavaScript team (Python/Java)
- ✓Cross-origin scenarios
- ✓Large test suites needing free parallelism
When to Choose Cypress
- ✓JavaScript-only team with browser-debugging focus
- ✓Component testing focus
- ✓Heavy use of Cypress plugins/ecosystem
