The short version
- Only Selenium has a free tier, so it costs nothing to try first.
- Each has a real cost: mabl tests are stored in a proprietary format and cannot be exported as runnable code, so migrating to Playwright or Cypress later means re authoring every test by hand.; Selenium flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically
- They diverge on capability: mabl covers Trainer recorder, Selenium covers W3C WebDriver.

What people use each for
The jobs each tool is most often brought in to do.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
mabl
- Tests are stored in a proprietary format and cannot be exported as runnable code, so migrating to Playwright or Cypress later means re authoring every test by hand.
- Auto healing can mask a genuine defect: if an element is removed and a similar one takes its place, the test adapts and passes when a user facing regression has actually shipped.
- Pricing is not published and is driven by concurrent run capacity, so the cost of shortening a two hour suite to twenty minutes is a renegotiation rather than a configuration change.
- Debugging a failure happens inside a hosted runner you do not control, which makes flakiness caused by test data or environment timing harder to reproduce locally than with a suite you run yourself.
- Native mobile application coverage is thin compared with the browser product, so teams with an iOS or Android app still need a second tool such as Appium or Maestro.
Selenium
- Flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically
- Setup involves drivers, versions and grid infrastructure that Playwright and Cypress bundle away
- Slower to run than tools that talk to browsers over a debugging protocol rather than WebDriver

Questions people ask
- Is mabl or Selenium better?
- Neither clearly leads. mabl starts at On request and Selenium at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, mabl or Selenium?

- What is mabl best used for?
- mabl is most often used for a qa team of two or three people responsible for regression coverage across a web application released weekly, an organisation that abandoned a selenium suite because maintenance consumed more time than manual testing did, teams that need accessibility scanning and functional regression reported in the same run, product companies where non engineers, such as support or business analysts, are expected to author tests. Of those, a qa team of two or three people responsible for regression coverage across a web application released weekly and an organisation that abandoned a selenium suite because maintenance consumed more time than manual testing did are not what Selenium is typically brought in for.

Answered from the vendors’ own pages
mabl: Can I export mabl tests to Playwright if we leave?
No. You can export documentation of the steps, but not runnable code. Budget for re authoring the suite.
Selenium: Is Selenium free?
Yes, open source with no licence fee. Paid costs come from grid infrastructure or services like BrowserStack.
mabl: Does auto healing actually work?
It works often enough to be the reason people buy it, but it cannot be verified from a demo. Trial it against your own application through at least two real releases.
Selenium: Selenium or Playwright?
Playwright handles waiting automatically and is faster to set up, which removes most flakiness complaints. Selenium wins on language breadth, browser coverage including Safari, and existing suites you already have.
mabl: Is mabl a replacement for unit tests?
No. It covers end to end journeys through a running application. Unit and integration coverage still belongs in your repository.
Selenium: Is Selenium still relevant?
Yes. Its WebDriver protocol is a W3C standard implemented by every major browser, and very large existing suites are not rewritten cheaply.
