Playwright vs Selenium: Choosing in 2026

Playwright has overtaken Selenium as the default choice for most new web projects, and for good reason: faster execution, built-in auto-waiting that eliminates a huge share of flaky test failures, and native support for multiple browser engines out of the box. That does not make Selenium obsolete. It makes the choice more specific than it used to be.

Should you choose Playwright or Selenium in 2026?

Choose Playwright for a new automation effort with no existing suite to protect. Keep Selenium if you already have a mature suite built on it, and extend that suite rather than rewriting it for its own sake. The two are rarely an all-or-nothing decision for a team that already ships tests.

Where Playwright wins clearly

• New projects with no existing automation investment to protect
• Teams that want tests written in TypeScript alongside their application code
• Modern single-page applications, where Playwright's auto-waiting handles dynamic content far more reliably than manual waits
• Parallel execution out of the box, without extra infrastructure to set up

Where a Selenium suite still makes sense

• An existing, mature Selenium suite with years of coverage built into it, where a rewrite would cost more than it returns
• Enterprise environments standardized on the Page Object Model with tooling built around it
• Legacy browser support requirements that Playwright's supported engine list does not fully cover
• Teams with deep existing Selenium expertise where the retraining cost outweighs the framework's benefits

The decision that actually matters

For a brand new automation effort, Playwright is the sensible default in 2026. For a team that already has a working Selenium suite, the right move is rarely a full rewrite for its own sake. Extend and maintain what already works, and consider Playwright for new coverage being built going forward, rather than treating the two as a single all-or-nothing decision.

What this looks like in practice

Most engagements that inherit an existing Selenium suite keep it running for regression on stable, well-covered paths, while building any new feature coverage in Playwright. Over time, the Selenium suite naturally shrinks as its covered paths get retired or rebuilt, without ever requiring a disruptive big-bang migration that pauses feature work to get there.
