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.; Split split is now a module of the Harness platform and split.io redirects to harness.io, so buying it means entering a Harness commercial relationship rather than a standalone flag vendor contract.
  • They diverge on capability: Katalon covers Low-code test recording, Split covers Feature flags with targeting.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Katalon

  • A QA team wanting a lower-code authoring layer over Selenium and Appium for testers without deep coding backgroundsnot Split
  • An organisation wanting test management and AI-assisted test maintenance bundled with automation authoring in one commercial productnot Split
  • A team needing occasional cross-browser or device cloud sessions without maintaining its own device lab or Selenium Gridnot Split
  • An enterprise wanting a single vendor and support contract for test authoring, management and cloud execution togethernot Split

Split

  • A product organisation that wants every release measured against conversion and latency by default, not only deliberate experimentsnot Katalon
  • Running A/B tests with real statistical significance rather than comparing two dashboard linesnot Katalon
  • Catching a regression at five per cent rollout because a guardrail metric fires before the change reaches everyonenot Katalon
  • A team already committed to Harness for CI and CD that wants flags in the same platform and contractnot Katalon

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.

Split

  • Split is now a module of the Harness platform and split.io redirects to harness.io, so buying it means entering a Harness commercial relationship rather than a standalone flag vendor contract.
  • Harness no longer publishes per-module prices, so an organisation that wants only feature management cannot get a list price and must negotiate a module out of a platform bundle.
  • The measurement engine needs traffic volume to reach significance, so a product with modest usage gets flags with an experimentation layer it will rarely be able to conclude anything from.
  • Metric attribution depends on correctly instrumented events flowing into Split, which is an integration project in its own right; without it you have paid for an experimentation platform and are using it as a flag switch.
  • As part of a larger DevOps suite the roadmap now competes with CI, CD, security and cloud cost modules for attention, so feature management is no longer the company’s single focus the way it was as an independent product.

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.

Split: Is Split still called Split?

It is now sold as Harness Feature Management and Experimentation after the Harness acquisition, and split.io redirects to harness.io.

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.

Split: Can I buy just feature flags?

Not from a price list. Harness publishes bundle tiers and directs single-module buyers to sales.

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.

Split: What does it do that a plain flag service does not?

It attributes changes in your product metrics to specific flags with statistical significance testing and alerts on guardrail metrics.

Split: Do we need a lot of traffic?

Yes. Statistical tests need volume to conclude, so low-traffic products get limited value from the measurement layer.
