Playwright vs Cypress vs Selenium for business web apps

Selenium is the oldest. It drives a real browser through a driver such as chromedriver or geckodriver, and it speaks Java, C#, Python, JavaScript and Ruby. It is a library, so you assemble the runner, the reports and the waiting logic yourself.

Playwright ships as a full kit. The test runner, assertions, trace viewer, screenshots and parallel workers come in one install. Cypress is also a full kit, but it runs inside the browser itself, which shapes everything it can and cannot do.

Those design choices matter more than any feature table. A tool that lives inside the page cannot easily open a second tab or act as a second logged in user. One that sits outside can.

Check the browser list before anything else. Playwright runs Chromium, Firefox and WebKit, so one script covers Safari’s engine without a Mac in the office. Selenium reaches Safari only through Apple’s own driver on macOS. Cypress added Firefox and WebKit support, though WebKit is still marked experimental.

Speed comes from how the tool waits. Playwright and Cypress retry an assertion until it passes or times out. Selenium does not, so teams write explicit waits and sprinkle sleeps. Slow suites are usually sleeps. Not the tool.

Parallel runs differ too. Playwright splits files across workers for free. Cypress parallelism is simplest through its paid dashboard. Selenium needs a Grid or a cloud service.

A flaky test passes on Monday and fails on Tuesday with no code change. The cause is nearly always timing: a button that is present but not yet clickable, or a table still loading.

Playwright checks that an element is visible, stable and enabled before it clicks. Cypress retries similarly. Selenium clicks the moment the element exists, and that is where the red builds start.

Whichever tool you choose, keep traces. Playwright’s trace viewer replays a failed run with network calls and DOM snapshots. Cypress offers video and screenshots. With Selenium you add them yourself. Failure evidence is what lets a new person debug without the original author.

Ask who will own the suite in two years. If your developers write TypeScript, Playwright and Cypress both fit. If your back end is Java and a QA engineer already knows TestNG, Selenium keeps everyone in one language.

Now apply the handover test. Could a stranger clone the repository, run one command and see green? Playwright and Cypress make that easy because the runner is bundled. A Selenium project often depends on a driver version, a Grid address and a wrapper class nobody documented.

Pick the tool your maintainers can already read. A clever suite in the wrong language gathers dust.

Choose Playwright when you need several browsers, multi tab flows such as a payment popup, or a suite a contractor will hand to your staff. Choose Cypress when the team is all JavaScript, the app is a single page build and Chrome is where your users are.

Choose Selenium when you already own a working suite, need a language Playwright handles less well, or must run on a legacy browser. Do not rewrite a stable suite to chase fashion.

Run a one week trial. Keep it small. Automate your login, one order and one report export in your top two candidates, then count how many lines broke when the screens changed. That count is your answer.
