The decision that matters is reliability, not brand
Playwright and Selenium can both protect a release. Startups fail when they pick a tool from a Twitter thread, then automate every button before the product is stable.
We recommend Playwright for most new web products: fast, modern traces, and a smaller flake surface in CI. We still use Selenium when a client already has a suite, a grid, or a compliance constraint that prefers it.
Where Playwright wins for early teams
Auto-waiting, tracing, and first-class TypeScript support mean a two-person QA pod can keep a smoke suite honest. That matters more than covering 200 selectors.
Wire the suite into CI on every pull request. Treat a flake as a production bug: quarantine, fix the cause, restore trust. A red suite that everyone ignores is worse than no suite.
When Selenium is still the right call
Keep Selenium if the existing investment is healthy, if you must target a specific grid, or if the org already has Selenium skills you do not want to throw away. Rewrites are expensive; stabilization is cheaper.
Our Growth and Scale retainers include this exact choice: we do not migrate you for sport. Book a free QA audit and we will say whether to keep, wrap, or replace what you have.
