Playwright · Reliable end-to-end tests
How does Playwright differ from Selenium?
Short answer
Playwright ships its own browser builds and talks to them directly, with auto-waiting and a built-in runner. Selenium drives browsers through the WebDriver protocol and generally needs explicit waits and separate tooling.
The biggest difference is the control layer. Selenium sends commands through the W3C WebDriver protocol to a browser driver. Playwright uses its own patched browsers and an event-driven protocol, which lets it observe and modify network traffic and DOM state more directly.
await page.getByRole("button", { name: "Add to cart" }).click();
await expect(page.getByRole("status")).toHaveText("Added to cart");The practical differences
- Playwright bundles browser builds; Selenium uses installed browsers plus drivers
- Playwright actions and web assertions retry automatically; Selenium typically needs explicit waits
- Playwright includes a runner, fixtures, tracing and parallel workers; Selenium usually pairs with JUnit, TestNG, pytest or another runner
- Selenium has a much larger ecosystem of language bindings, grids and legacy support
- Playwright supports Chromium, Firefox and WebKit; Selenium supports those and more browser and driver combinations
- Playwright network interception is a first-class API; Selenium relies on CDP-specific workarounds
Selenium is a reasonable choice when an organisation already has a mature Grid, a non-JavaScript stack or a hard requirement for a browser or driver that Playwright does not ship. Playwright usually wins on developer experience for new greenfield browser suites.
Follow-ups you should expect
Interviewers use these to check whether the first answer was understanding or memorisation.
- 1Why does Playwright not need a separate browser driver?
- 2When would you still choose Selenium?
- 3Does Playwright support the WebDriver protocol?
- 4How does auto-waiting change test maintenance?
Say it in the interview
Selenium drives browsers through WebDriver, while Playwright ships patched browser builds and controls them directly. That gives Playwright built-in auto-waiting, network interception, tracing and a test runner. Selenium has a broader ecosystem and stronger legacy and grid support, so it is still a valid choice in some organisations. For a new browser suite I would usually pick Playwright because the defaults remove a lot of flaky wait code.
Use this as a model, not a script. Saying it in your own words is what makes it survive follow-up pressure.
