Choose Playwright for a new end-to-end suite in JavaScript, TypeScript, Python, Java or .NET: it bundles a test runner, auto-waiting, isolated contexts and a trace viewer. Choose Selenium when you need Ruby or Kotlin, branded Safari, an existing WebDriver suite or your own Grid. Both are free, open source and drive real browsers.
Playwright and Selenium both automate real browsers, and both are free and open source. They differ in what comes in the box, how they talk to the browser and how much you assemble yourself. This post compares them point by point from each project’s own documentation, read on November 5, 2026, and ends with a rule for choosing. We make Sybqa, which drives browsers with Playwright, so weigh the last section accordingly.

| Point | Playwright | Selenium |
|---|---|---|
| What it is | An end-to-end test framework that bundles a test runner, assertions, isolation, parallelization and tooling | An umbrella project: WebDriver (the browser API), IDE (a recorder) and Grid (remote and parallel runs). You bring the test runner |
| Languages | JavaScript and TypeScript, Python, Java and .NET | Java, Python, C#, Ruby, JavaScript and Kotlin |
| Browsers | Chromium, WebKit and Firefox builds it installs, plus branded Chrome and Edge, and mobile emulation | Chrome, Edge, Firefox, Safari and Internet Explorer, through each vendor’s driver |
| How it talks to the browser | Its own patched browser builds; it does not work with branded Safari or Firefox | WebDriver, a W3C Recommendation, and WebDriver BiDi for streaming browser events |
| Waiting | Auto-waits for actionability checks before each action, and assertions retry | Implicit or explicit waits that you set; mixing them is discouraged |
| Isolation | A fresh browser context per test by default | Up to your test framework and how you create and quit drivers |
| Debugging | HTML reporter, UI Mode and Trace Viewer | Your test framework’s reports, plus BiDi events such as console messages and JavaScript errors |
| Scaling out | Parallel workers and sharding in its test runner | Selenium Grid routes commands to browsers on other machines |
| Recording tests | Codegen generates tests as you click | Selenium IDE, a Chrome and Firefox extension, records your actions |
Playwright Test describes itself as an end-to-end test framework for modern web apps that bundles a test runner, assertions, isolation, parallelization and rich tooling. Run npm init playwright@latest and you get a config file, an example test and the browsers it needs. One install covers writing, running and reporting.
Selenium describes itself as an umbrella project for a range of tools and libraries that support browser automation. WebDriver is the API your code calls. It uses the automation APIs that browser vendors provide, so it drives the browser as a real user would. You choose the test framework around it, such as JUnit, pytest or Mocha, plus your own reporting.
That split explains most of the other rows. Playwright makes more choices for you. Selenium leaves them to you and works with a wider set of languages and browsers.
Playwright is available for JavaScript and TypeScript, Python, Java and .NET, and all core browser automation features work in every language. Its own test runner, Playwright Test, comes with the Node.js version. In Python the docs recommend the Pytest plugin; in Java you pick JUnit or TestNG; .NET has base classes for MSTest, NUnit and xUnit.
Playwright installs its own Chromium, Firefox and WebKit builds with npx playwright install, and can also run branded Google Chrome and Microsoft Edge. Its docs say it does not work with branded Firefox or Safari, because it relies on patches. For the closest-to-Safari result they suggest running WebKit on a Mac.
Selenium’s documentation shows examples in Java, Python, C#, Ruby, JavaScript and Kotlin, and covers Chrome, Edge, Firefox, Internet Explorer and Safari. On a Mac, safaridriver comes with the operating system. Since Selenium 4.6, Selenium Manager finds, downloads and caches the right driver for you, which removes the old chromedriver version mismatch. Since 4.11 it can also download Chrome, then Firefox and Edge.
Selenium’s own docs call timing the most common challenge in browser automation and one of the main causes of flaky tests: the code runs before the page is ready. Selenium gives you two tools. An implicit wait is a global setting, 0 by default, that applies to every element lookup. An explicit wait polls for a condition you name, such as an element being displayed. The docs warn not to mix the two, because the timeouts can add up unpredictably.
Playwright waits by default. Before click() it checks that the locator resolves to exactly one element and that the element is visible, stable, enabled and not covered by another element. Its assertions, such as toBeVisible() and toHaveText(), keep retrying until the condition is met or the timeout passes.
Neither removes flakiness on its own. A test that asserts on the wrong thing is still wrong. Playwright simply asks you to write fewer waits by hand.
Isolation. Playwright runs each test in its own browser context, an incognito-like profile with its own cookies, local storage and session storage. Contexts are cheap, so a test cannot inherit state from the one before it. Several contexts in one test can stand in for two users, such as an admin and a customer. In Selenium, isolation depends on how your framework starts and quits drivers.
Debugging. Playwright’s HTML report filters runs by passed, failed, flaky and skipped. Its Trace Viewer lets you step through each action with DOM snapshots, network, console and errors. By default the generated config records a trace on the first retry of a failed test. Selenium is moving from WebDriver Classic to WebDriver BiDi, a W3C protocol created with the browser vendors, which streams network requests, console messages and JavaScript errors to your script.
Scale. Playwright’s runner runs tests in parallel across workers and supports sharding. Selenium Grid routes WebDriver commands to browsers on remote machines, for parallel runs across browser versions and operating systems. Grid suits teams that host their own browser farm or rent a Selenium-compatible one.
For most new projects with engineers who will own the tests, Playwright needs less setup. Selenium is the steadier choice when standards, language or browser coverage matter more than convenience. Whichever you pick, write tests for the few journeys that must never break, such as signup and checkout, and end each one with an assertion on the outcome, not just a page load.
Both tools assume someone will write and maintain code: selectors, fixtures and CI setup. If you built a site with Lovable, Bolt, v0 or Cursor and have no suite, start with the checks to run before launch, then decide what to automate.
Sybqa is one way to get a first read without code. Paste a link, review the plan, and it runs the journeys in a real browser at desktop, phone and narrow widths. The report lists each check as passed, failed, blocked, not run or needs review, with evidence. Sybqa uses Playwright under the hood. An approved plan exports as a Playwright spec you can review and keep in your repository. Sybqa does not export Selenium tests, and it does not replace a suite your team owns. The Playwright vs Sybqa comparison sets out when each is the right choice.
For a new suite in a language Playwright supports, it usually needs less setup: the runner, auto-waiting, isolation and traces come in one install. Selenium is better when you need Ruby or Kotlin, branded Safari or Internet Explorer, a W3C WebDriver suite you already have, or Selenium Grid.
No. Selenium WebDriver is a W3C Recommendation, Selenium Manager has handled drivers and browsers for you since versions 4.6 and 4.11, and the project is moving to WebDriver BiDi, a W3C protocol it created with the browser vendors.
Yes. Playwright does not depend on Selenium. Its installer sets up a config, an example test and the browsers, and its docs start from there.
Not with the branded Safari app. Playwright runs its own WebKit build, and its docs suggest running WebKit on a Mac for the closest-to-Safari result. Selenium drives Safari through safaridriver, which comes with macOS.
Measure your own suite rather than trust a general benchmark. Waiting strategy and parallel runs usually matter more than the tool: fixed sleeps slow any suite, Playwright waits only until each check passes, and both can run tests in parallel.
Playwright. Sybqa drives real browsers with Playwright and can export an approved plan as a Playwright spec. It does not export Selenium tests.
