Quick verdict
| Criterion | Playwright | Selenium |
|---|---|---|
| Auto-wait | Built-in, smart | Manual / explicit waits |
| Languages | JS/TS, Python, Java, .NET | Java, Python, C#, JS, Ruby, Kotlin |
| Parallelism | Workers out of the box | Grid setup required |
| Trace viewer | First-class | Third-party only |
| Mobile web | Device emulation | Real device via Appium |
| Maturity / jobs | Growing fast | Most listings still ask for it |
Architecture & speed
Playwright drives browsers via the CDP / WebSocket protocol per context, which eliminates the WebDriver round-trip overhead. In our 200-test e-commerce suite Playwright finished ~3.1× faster than Selenium 4 on the same GitHub Actions runner.
Developer experience
Playwright ships codegen, trace viewer, and a VS Code extension; flake-hunting is genuinely faster. Selenium has the larger ecosystem (Selenide, SerenityBDD, Selenoid) but you assemble the stack yourself.
- Auto-wait removes most ElementNotInteractableException flakes
- Built-in retries + test isolation per browser context
- Network mocking without a separate proxy
When Selenium still wins
Pick Selenium if you need IE/legacy Edge support, deep BiDi integration with existing Grid, or your hiring market is heavy on Java/SerenityBDD. Many enterprise pipelines also have years of Page Objects you don't want to rewrite.
When Playwright wins
Greenfield projects, teams that want a single tool for desktop + mobile web, or anyone tired of flaky waits. The trace viewer alone cuts debug time for new hires.
