The short version
- Only Testsigma 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.; Testsigma the natural language layer is a fixed vocabulary rather than real English, so testers spend the first weeks learning which phrasings the parser accepts, which is learning a language after all.
- They diverge on capability: mabl covers Trainer recorder, Testsigma covers Natural language authoring.
- Prices and features above were last checked on 31 August 2026.

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.
Testsigma
- The natural language layer is a fixed vocabulary rather than real English, so testers spend the first weeks learning which phrasings the parser accepts, which is learning a language after all.
- Anything conditional or arithmetic falls through to custom Java or JavaScript, and that code lives in the platform editor rather than your repository, where it gets no code review and no version history you control.
- The community edition lags the cloud product and is not the version the vendor demonstrates, so a self hosted evaluation can understate or overstate what you would actually buy.
- Cloud execution is billed separately from authoring seats, so a suite that grows from two hundred to two thousand tests changes the bill without anyone changing the plan.
- Support and engineering are concentrated in Indian time zones, which slows incident turnaround for teams working in the Americas.

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.
Testsigma: Is the open source edition genuinely usable in production?
Yes for self hosted execution, though it trails the cloud version on newer features and you maintain the grid yourself.
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.
Testsigma: Do testers need to know Selenium?
Not to write ordinary steps. They will need someone who does as soon as the suite needs custom functions or awkward waits.
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.
Testsigma: Can it test native iOS and Android applications?
Yes, through Appium underneath, on the hosted device grid or your own devices.
