The short version
- Each has a real cost: Katalon real cost stacks three separate charges, per-seat authoring licence, the True Platform add-on for test management, and per-session cloud execution, so the advertised seat price significantly understates total spend for a team running cloud tests regularly.; 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.
- They diverge on capability: Katalon covers Low-code test recording, mabl covers Trainer recorder.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Katalon
- Real cost stacks three separate charges, per-seat authoring licence, the True Platform add-on for test management, and per-session cloud execution, so the advertised seat price significantly understates total spend for a team running cloud tests regularly.
- Since it is built on Selenium and Appium underneath, a team with strong automation engineers can replicate most of the core capability for free, paying only for optional cloud execution elsewhere, making Katalon's value proposition mainly about authoring speed rather than unique capability.
- The steep first-three-seats discount versus the fourth-seat-and-beyond price means cost per seat rises sharply as a team scales past three testers on Katalon Studio alone.
- Low-code recorded tests can become brittle and hard to maintain at scale in the same way any record-and-playback approach does, requiring the team to still write real code for complex scenarios.
- Enterprise pricing is quote-only, so the largest deployments lose the pricing transparency the published seat tiers otherwise offer.
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.

Answered from the vendors’ own pages
Katalon: Is Katalon free?
No, though a 30-day free trial with no credit card is offered; the product is commercial with per-seat licensing.
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.
Katalon: Does Katalon replace Selenium and Appium?
No, it is built on top of them; Katalon adds a low-code authoring layer, test management and cloud execution rather than a different automation engine.
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.
Katalon: Is cloud execution included in the seat price?
No, TestCloud cross-browser and mobile sessions are billed separately, at 197 US dollars a session monthly or 1,899 annually per session.
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.
