Katalon vs Testsigma: AI, Mobile, Ease of Use, and Cost

Katalon vs Testsigma: the short answer

• Testsigma positions itself as an agentic test automation platform. You write test steps in natural language, run them on Testsigma's cloud browsers and devices, and use Atto, which Testsigma calls an "AI coworker", to generate, run, heal, and diagnose tests.
• Katalon Studio is a test automation IDE for web, mobile, and API testing, plus Windows desktop testing on a paid plan (Professional or Enterprise), with no-code, low-code, and full-code authoring. Katalon True adds Katalon TestOps for test management, TestCloud and Katalon Runtime Engine (KRE) for execution, and TrueTest for production insights.
• Testsigma is stronger for teams that want plain-English tests, no local setup, and agents that take on authoring and maintenance work in a hosted product.
• Katalon is stronger for teams that want to start free, see prices up front, mix recorded and scripted tests, and connect authoring and test management to production data.

Katalon vs Testsigma at a glance

The table compares Katalon and Testsigma as of November 2026. Katalon details come from the Katalon pricing page and the Katalon True product pages; Testsigma details come from testsigma.com, its pricing page, and its documentation.

What is Testsigma?

Testsigma is a cloud-based test automation platform. It positions itself as an agentic test automation platform for QA teams and describes Atto, an "AI coworker" made up of more than 25 agents for tasks such as test authoring, planning, coverage analysis, execution, and healing. Testsigma says a human approves agent output before anything ships.

Tests are written as natural-language steps, which lowers the barrier for testers who don't code. When you need logic the steps can't express, you add custom functions. As of November 2026, Testsigma lists web, mobile (native, hybrid, and Flutter), API (REST and SOAP), Salesforce, SAP, and Windows desktop testing. Windows desktop tests run on your machine through the Testsigma agent rather than in its cloud.

Testsigma also sells a separate product, Test Management by Testsigma, with test plans, two-way Jira sync, and Atto agents for sprint planning, test case generation, and bug reporting. As of November 2026, it lists a free-forever plan.

There is also an open-source GitHub project from its earlier Community edition. Its last release was in August 2023, and testsigma.com no longer mentions it, so treat it as a legacy project rather than a current product.

What is Katalon True?

Katalon True is Katalon's AI platform for software quality. It brings authoring, test management, execution, and production insight together, with each product doing one job. Katalon is rated 4.5 on G2.

Katalon Studio

Katalon Studio is where you author tests for web, mobile, and API apps, plus Windows desktop apps on a paid plan (Professional or Enterprise), using no-code, low-code, or full-code. You can record a test, edit it as keywords, and open the script view to add Groovy or Java, all in the same test case. That lets testers who don't code and engineers who do share one project.

Katalon TestOps

Katalon TestOps handles test management and manual testing: test plans, cycles, coverage tracking, and release gates on one shared report. It holds manual and automated results in one place. New in TestOps, the AI Test Runner executes your manual test cases autonomously, with human approval at each step.

TestCloud and Katalon Runtime Engine

TestCloud runs test suites in parallel on real browsers and devices, so you don't maintain your own lab. Katalon Runtime Engine (KRE) runs Studio tests headless, from the command line, and in CI tools such as Jenkins, GitHub Actions, Azure DevOps, and GitLab.

TrueTest

TrueTest shows how real users move through your product in production and where your tests miss those journeys. It helps generate tests for the gaps, which your team reviews before adding them to suites. That is the production insight job, separate from test management in TestOps.

Is Testsigma easier to use than Katalon?

For testers who don't code, Testsigma usually has the shorter start. You work in the browser, write steps in plain English, and run them on hosted browsers and devices without installing anything for web and mobile tests.

Katalon Studio is a desktop IDE you install. Testers who don't code can record tests and build them from keywords, and engineers can open the same test case in the script view. There is more to learn than in a plain-English editor, but you also get more control: an Object Repository with several locators per object, custom keywords, data-driven tests, and full access to the code when a test needs it.

So ease of use depends on who maintains the suite. If most authors are manual testers moving into automation, Testsigma's natural-language steps fit. If testers and automation engineers share the same tests, Studio's two views of one test case tend to suit the handoff better.

AI features and self-healing

Both tools now put AI at the center of authoring and maintenance, but they package it differently. This post doesn't rank the two; trial both on your own app.

Testsigma describes Atto as a set of 25+ agents that generate tests from requirements, run them, heal broken steps, and diagnose failures. As of November 2026, its Pro plan includes Testsigma Copilot and auto-healing, its Enterprise plan adds AI test case generation, and Autonomous Testing is listed as "Upcoming" on Enterprise.

Katalon Studio includes the Katalon AI Assistant, which generates scripts from natural language, explains scripts, and helps fix failures. AI self-healing retries alternative locators when the UI changes and suggests a working one, which is saved only after you approve it. AI failure root cause analysis explains why a run failed, and an MCP server connects Studio to your own AI tools. These come with a paid plan (Professional or Enterprise). You can use your own AI provider API key on a paid plan, and Enterprise adds organization-wide bring your own AI provider.

Across Katalon True, the AI Test Runner in TestOps runs manual test cases with human approval at each step, and TrueTest uses production data to show which user journeys your tests don't cover.

Mobile testing support

Both tools test Android and iOS apps, so the difference is in how you run them.

Testsigma lists native, hybrid, and Flutter apps, run on its own real device cloud, which is included in its plans. If you want a device lab without a separate contract, that bundling is a real convenience.

Katalon Studio tests Android and iOS apps and mobile browsers, with mobile and web objects in the same Object Repository. You can run on local devices and emulators, or on real devices and browsers in TestCloud, a paid add-on that works with any Studio plan, including Free. Mobile tests can also share data files and custom keywords with your web and API tests.

If Flutter apps are central to your product, check each tool's support against your own app before you decide.

Unified testing: web, mobile, API, and desktop

Both tools cover more than one application type in a single product.

Testsigma covers web, mobile, and API testing in its cloud, plus Windows desktop through its local agent, and it lists Salesforce and SAP among supported applications.

Katalon Studio covers web, mobile, and API testing on every plan and Windows desktop testing on a paid plan (Professional or Enterprise), with one Object Repository and one project for all of them. Across Katalon True, the same tests feed TestOps for test management and reporting, and TrueTest adds what real users do in production.

If your suite leans on Salesforce or SAP, test Testsigma's built-in support. If it spans web, mobile, API, and desktop with a mix of manual and automated testing, Katalon True keeps those in one workflow.

Deployment and execution

Testsigma is a hosted cloud product. As of November 2026, its Enterprise plan lists public, private, or on-prem cloud deployment, a private grid, and SSO. So on-prem is available, but on Enterprise rather than on Pro.

Katalon Studio runs on your own machine, and local execution is included on every plan. Parallel execution needs a paid plan (Professional or Enterprise). Command-line and CI runs need KRE, a paid add-on used with Professional or Enterprise. Cloud runs need TestCloud, an add-on that works with any plan, including Free. Katalon Enterprise adds SSO, role-based access control, and private cloud or on-premises deployment.

Testsigma bundles more execution into one subscription. Katalon splits it into add-ons, so you pay for CI or cloud runs only when you need them.

Pricing: which is cheaper for a small QA team?

Testsigma doesn't publish prices for test automation. As of November 2026, its pricing page lists two automation plans, Pro and Enterprise, both by custom quote, and no free automation plan. Testsigma also offers a free trial, per its homepage. Its separate Test Management by Testsigma product lists a free-forever plan, with premium plans from $14 per user per month, as of November 2026.

Katalon plans, as of November 2026, from the Katalon pricing page:

• Free: Katalon Studio with record and playback, local authoring, and local execution for web, mobile, and API tests.
• Professional: $1,800 per seat per year, billed annually (about $150 a month). Adds Windows desktop testing, AI self-healing, the Katalon AI Assistant, the MCP server, parallel execution, and BDD (Cucumber) testing.
• Enterprise: custom pricing, adding SSO, role-based access control, audit logs, and private cloud or on-premises deployment.

You can start with a 30-day free trial. KRE and TestCloud are add-ons priced separately. For a small team, Katalon lets you start test automation at no cost and see the per-seat price before you talk to anyone. Testsigma's quote may still work out well, especially since it bundles cloud devices, so ask for one and compare totals, including any add-ons you'd need on the Katalon side.

When Testsigma is the better fit

Testsigma is often the better choice when:

• Most of your authors don't code and you want them writing plain-English tests from the first day.
• You want agents to take on authoring and maintenance work in a hosted product, and you're comfortable reviewing what they produce.
• You want a device cloud bundled into one subscription rather than buying cloud execution as an add-on.
• Salesforce or SAP testing is a priority and you want it listed as built-in support.

When Katalon is the better fit

Katalon is often the better choice when:

• Your team mixes testers who don't code with engineers who do, and you want recorded, keyword, and scripted steps in the same test case.
• You want to start free and see prices up front, then add Professional seats when you need desktop testing, AI self-healing, and parallel runs.
• You want test management and automation results in one place, with Katalon TestOps holding manual and automated results, plans, cycles, coverage, and release gates on one shared report.
• You want production data to guide coverage, with TrueTest showing which real user journeys your tests miss.

Is Katalon or Testsigma better?

Neither is better for every team. Testsigma is better when you want plain-English tests, a hosted device cloud, and AI agents doing much of the authoring. Katalon is better when you want a free automation plan, published per-seat automation pricing, code and no-code in one test case, and a lifecycle that runs from authoring to production insight.

The most reliable way to decide is to run both against your own application: Katalon's 30-day free trial and a Testsigma trial. Automate the same three or four critical flows in each, change the UI on purpose, and compare how much work it takes to get the tests passing again.
