In short: Playwright vs Selenium comes down to your team and your existing tests. Playwright is the easier start for a new suite on a modern web app. Selenium still makes sense for large existing suites, many languages and wide browser coverage. The tool matters less than who keeps the tests running after they are built.

Browser test automation has a clear favourite in 2026, at least in downloads. In the month to 27 September, the Playwright packages were downloaded far more often than Selenium’s, on both npm and PyPI. Downloads don’t equal test suites, though. Playwright is also used for web scraping and AI agents, and much of Selenium’s use runs on Java, which these numbers don’t include.

So the question for most teams is still Playwright vs Selenium: which one fits us? We don’t sell either tool, so here is an independent view.

What is the difference between Playwright and Selenium?

Both tools drive a real browser the way a user would. They open pages, click, type and check what appears. The difference is in how they do it and how much they give you out of the box. Selenium has been around since 2004 and talks to browsers through WebDriver, an official W3C standard that browser makers support. It works with many languages and almost any browser. You add waiting, reports and parallel runs yourself, or with extra tools. Playwright comes from Microsoft and was released in 2020. It controls Chromium, Firefox and WebKit directly and ships with a test runner. It waits for elements automatically, runs tests in parallel and records a trace you can replay step by step. For a new team, that means fewer decisions on day one.

Is Selenium outdated?

No. Selenium is older, and it shows in how much you build yourself, but it is not outdated. It runs on an official web standard, it supports many languages, and a huge number of companies depend on it. Selenium 4 switched fully to the W3C WebDriver standard. For a team with a large Selenium suite in Java or C#, moving away can cost more than it gains. Selenium also fits well when you have to test many browser versions through a grid, or when your testers already know it well. The honest trade-off: you spend more time on the framework around your tests. Waiting, retries, reporting and parallel runs are yours to build and maintain. If nobody on the team enjoys that work, it tends to decay quietly.

When is Playwright the better choice?

Playwright is usually the better choice for a new test suite on a modern web application. It removes a lot of set-up work. It waits for elements by itself. That removes a common cause of flaky tests, which fail at random because the page wasn’t ready yet. Its trace viewer shows each step with screenshots, so a failed test is quicker to understand. It runs tests in parallel without extra tools, which keeps a growing suite fast. And it supports the languages most teams use, including Python, Java and .NET. Choose Playwright when you start from scratch or when your current tests are flaky mostly because of timing. It also fits when developers and testers want to write tests in the same language as the app. Check one thing first: that it runs on the browsers your users actually use.

What about Cypress?

Cypress is popular with front-end developers, because it runs inside the browser and gives fast, visual feedback while you write a test. It only supports JavaScript and TypeScript. Its WebKit support, the engine behind Safari, is still experimental. Parallel runs at scale need its paid cloud service or other tools. That makes Cypress a good fit for a JavaScript team that tests its own front end. It fits less well for a test team that covers several apps, languages or browsers. If you outgrow it, Playwright is the closest alternative, and the tests look similar enough to make a move manageable.

Should you migrate an existing Selenium suite?

Only if the current suite costs you more than the move would. Rewriting working tests adds nothing for your users. The good reasons to switch are practical: tests that fail at random, runs that take hours, or a framework that only one person understands. If none of those apply, keep Selenium and invest in the suite. If they do, move step by step:

1. List the ten tests that fail most often or matter most.
2. Rebuild those in Playwright and run them next to the old ones for a few weeks.
3. Compare stability and run time, and write new tests in Playwright from now on.
4. Continue in batches. Switch off old tests only when the new ones are trusted.
5. Decide before you start who maintains the result, and set an end date.

What this means for your team

Pick the tool that fits your application, your languages and the people who will maintain the tests. Then plan for the part that decides whether the choice pays off: keeping the suite running. A Playwright suite that nobody maintains breaks just as surely as a Selenium suite that nobody maintains. In conversations about test automation, we often hear “we already have that sorted”. A few questions later, it turns out one person built almost all of it and maintenance was never planned in. A new tool doesn’t change that.

Nekst is independent and works with both. When we start at a client, the first days go to reviewing the current tests with the team and finding the bottlenecks. The tool choice follows from that. With Test Automation as a Service, we pick the tool with your team, build the suite and keep it running every night. You decide what ships.

Frequently asked questions

Is Selenium better than Playwright?

Neither is better for every team. Selenium wins on language choice, browser range and existing know-how. Playwright wins on set-up time, built-in waiting, debugging and parallel runs. For a new suite on a modern web app, Playwright is usually quicker to get stable.

Is Playwright going to replace Selenium?

For new projects, it often does already. Selenium will stay around for a long time, because many large suites run on it and it is built on an official web standard. Expect both to exist side by side for years.

Is Selenium outdated now?

No. It is older and asks more set-up work, but it is actively maintained and supported by browser makers through the WebDriver standard. For large suites in Java or C#, it is still a sound choice.

Is Playwright the future?

It is downloaded far more often than Selenium or Cypress right now, and it keeps adding features. That makes it a safe choice for a new suite. The long-term value of any tool still depends on whether your tests are maintained.
