Playwright vs Selenium WebDriver
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

The metric that actually scales your invoice.
Free and open source. Microsoft also sells a hosted parallel-runner service; the library itself has no paid tier.
Free and open source. The real cost is grid infrastructure or a device-cloud subscription.

Strengths
- Auto-waiting and web-first assertions remove most of the sleep() flake that plagues older tools.
- The trace viewer — DOM snapshots, network, console and screenshots per step — is the best failure triage in the category.
- True WebKit support, so Safari bugs are caught on Linux CI without a Mac.
- The widest language and browser support of anything in the category, including legacy browser versions.
- A W3C standard, so it will outlive any single vendor. Skills transfer between employers.
- Every device cloud speaks Selenium, which keeps you portable between vendors.
Limitations
- No native mobile app support. Mobile means an emulated viewport, not a real device.
- The API surface is large; teams without a conventions document end up with four ways to write the same locator.
- Component testing is still experimental compared to the E2E runner.
- No built-in waiting strategy, reporting, parallelism or assertions — expect to assemble and maintain a framework around it.
- Explicit waits are your problem, and getting them wrong is the number one source of flake in real Selenium suites.
- Out-of-process communication makes it slower than Playwright or Cypress.
Best for
Teams that write their own tests and want the lowest-flake open-source option available.
Enterprises with polyglot teams, legacy browser requirements, or an existing grid investment.
All of these integrate with: Jenkins, Docker.
