Look elsewhere only when language or platform forces the issue. If your team doesn't write JavaScript, a multi-language driver fits. Prefer tests run from a dedicated app? Pick a runner that ships with one. For simple scripting, a JavaScript library is enough, and if native mobile apps are in scope, choose a framework that covers those too.
Playwright drives Chromium, Firefox and WebKit through one API, and it's available for TypeScript, Python, .NET and Java. That's a wide reach, so if you're a developer or QA engineer looking at alternatives, it's usually because of one specific gap: a language your team uses, a platform you need to test, or a style of working that suits your people better.
Below, nine options are grouped by that gap. Jump to whichever group describes your problem.
What you'd give up by leaving
Be clear-eyed about this before you start. Playwright gives you one API across three browser engines and four languages. Several options on this page cover fewer engines or one language, so a move can mean running two tools where you used to run one.
That's fine if the gain is real, such as a QA team that can finally write tests without a developer, or a product that now needs phone testing. It's a poor trade if the only reason is that a new name is getting attention.
Count the hidden work too: CI configuration, reporting, test data helpers and the habits your team has built up. None of that moves with you automatically, and rebuilding it is often the biggest part of a migration.
Engine coverage is the trap
Several alternatives are narrower than what you have today. Puppeteer's own page says it controls Chrome or Firefox, while WebKit is one of the three engines Playwright drives. If your test plan includes the engine behind Safari, a Chrome-and-Firefox library won't cover it, and you'd need a different pick or a second tool.
Selenium is the counterpoint, with its own page naming Chrome, Firefox, Edge and Safari. So when you shortlist, put browser coverage at the top of the checklist, not the bottom. A faster or friendlier framework doesn't help if it can't open the browser your customers use.
When your team writes another language, or no code at all
If JavaScript isn't your team's home turf, these three meet people where they are. They're the ones to try when the bottleneck is who can write and maintain tests.
Katalon
Useful when manual testers and developers need to share one tool. Katalon Studio lets each write tests their own way, from no-code through low-code to full code.
Robot Framework
An open source automation framework you grow with libraries written in Python, Java and other languages, so your team can extend it in the language it already knows.
Selenium
Works through the W3C WebDriver standard and accepts scripts in six languages, two more than Playwright's four. Our Selenium head-to-head covers the trade-offs.
Lean JavaScript libraries for scripting
If you mainly script a browser for checks, testing your own app or quick automation, a small library can be enough.
Puppeteer
A JavaScript library that controls Chrome or Firefox over the DevTools Protocol or WebDriver BiDi.
Taiko
An open source Node.js library for testing modern web applications.
Runners that come with their own app
Some teams prefer a dedicated application around their tests rather than working only from the command line. These two ship a runner with an app.

Cypress
Cypress App is its open-source testing application, and Cypress pairs it with Cypress Cloud, a separate product for scaling your testing. See our Cypress comparison for the detail.
TestCafe
TestCafe pairs two things: a test runner it describes as free and open source, and a separate desktop app. Try both halves during your trial, since a team may take to one and not the other.
Frameworks that reach past the web browser
If your product also lives on phones or the desktop, a framework that covers those saves you running two separate stacks.
Nightwatch.js
A Node.js powered end-to-end testing framework covering web and native mobile applications.
WebdriverIO
One framework for three surfaces. WebdriverIO calls itself open source test automation for web, mobile and desktop apps, so a single suite can follow your product off the browser.
Open source, and what sits on top
Most names here describe themselves as open source, including Robot Framework, Taiko, TestCafe and WebdriverIO. Cypress is the one on this page that pairs its open app with a separate product for running tests at scale. When you trial anything, note which features you lean on come from the open part, and which would need an add-on later as your suite grows.
The nine compared
| Framework | Group | Good first trial for |
|---|---|---|
| Katalon | Other language or no-code | Mixed-skill QA teams |
| Robot Framework | Other language or no-code | Teams extending in Python or Java |
| Selenium | Other language or no-code | Safari and Edge coverage |
| Puppeteer | JavaScript library | Quick scripts |
| Taiko | JavaScript library | Node teams |
| Cypress | Runner with an app | Teams who want a test app |
| TestCafe | Runner with an app | Teams who like a desktop tool |
| Nightwatch.js | Past the browser | Web plus phone apps |
| WebdriverIO | Past the browser | Web, phone and desktop |
Treat the last column as a place to begin, not a verdict. Any of these can be pushed into other jobs, but trialling a framework against the job it was built for gives you the fairest read.
Good and weak reasons to move
- Good: your testers write Ruby or Kotlin and can't contribute to the current suite.
- Good: your product now has a phone app that needs the same end-to-end checks.
- Good: non-developers need to author tests without writing code.
- Weak: a new framework is popular this month.
- Weak: your current tests are flaky, which is usually about how tests are written rather than the framework.
A two-sprint trial plan
- Pick ten existing tests that cover your riskiest user journeys.
- Rewrite them in the candidate framework, using the language your team prefers.
- Run both suites in your CI pipeline for two sprints, side by side.
- Compare how often each suite fails for reasons that aren't real bugs.
- Check every browser engine your customers use is covered.
- Ask the people who'll maintain the tests which suite they'd rather debug.
- Only then decide whether to migrate the rest.
Don't rewrite your whole suite on a hunch. Ten well-chosen tests tell you almost everything about debugging, flakiness and fit, and you can bin them cheaply if the trial says no. For a wider view of the field, our round-up of test automation tools lists more options.

Frequently asked questions
How do Selenium's languages compare with Playwright's?
Selenium accepts six, against Playwright's four. Ruby and Kotlin teams are the clearest case, since neither language appears on Playwright's TypeScript, Python, .NET and Java list.
Can these run in my CI pipeline?
Check each framework's docs for a guide to your CI service, and run a short pilot job there before you move the whole suite.
Can Katalon cover API and desktop tests too?
Yes. Katalon Studio authors web, mobile, API and desktop tests.
Is Robot Framework only for testing?
No. It's built for test automation and RPA, so the same team can automate repetitive business tasks with it.
Will I have to rewrite my tests to switch?
Expect to, because each framework has its own API. That's why a small trial should come before any migration.
