Katalon Alternatives: Low-Code, AI and Open-Source Options for QA Teams

Katalon Studio is a popular first automation tool because one project can hold web, mobile, API and desktop tests, written with a recorder, keywords or Groovy code. Teams still look elsewhere: some want authoring in the browser instead of a desktop app, some need deeper Windows desktop support, some run SAP and other enterprise apps, and some would rather own a coded framework. This guide groups the main Katalon alternatives by need, explains where each fits and where it falls short, and ends with a simple way to choose. It is based on vendor pages and our testing tools directory, read on 27 October 2026. If you are still deciding on Katalon itself, read our Katalon Studio review first.

SmartBear's TestComplete is the closest match to Katalon's model. It covers web, mobile and Windows desktop apps, and you can record, use keyword tests or write scripts. It sits in a wider SmartBear family that includes ReadyAPI for API testing and Zephyr and QMetry for test management, which helps if you want one vendor.

Ranorex Studio also mixes recording with code, but its code is C# or VB.NET instead of Groovy. That suits .NET teams and Windows desktop-heavy products.

Watch out for: both are Windows desktop apps, so Mac-only teams need a Windows machine or VM. Like Katalon, both use a paid licence model.

Testsigma runs in the browser, and tests are written as plain-English steps with AI features that help create and maintain them across web, mobile and API. mabl is a low-code, AI-assisted cloud service aimed at teams shipping often. testRigor goes furthest toward plain language: tests read like instructions to a person.

These suit teams where manual testers want to automate without learning a language. For a closer look at how they compare on AI features, see our mabl vs Testim vs Katalon comparison.

Watch out for: review every AI self-healing change, and check that you can export tests if you ever leave.

Tricentis Tosca uses model-based automation: you scan an application into reusable modules, then build tests from them. It is common in large companies testing SAP and other packaged apps, and Tricentis also offers qTest for test management and NeoLoad for performance. Leapwork builds tests as visual flowcharts and targets web, desktop and enterprise apps.

Watch out for: both take time to roll out and are usually bought at company level, so they rarely fit a small team.

Because Katalon is built on Selenium and Appium, moving to plain Selenium keeps the same browser engine but gives you full control in Java, Python, C# or JavaScript. Playwright is the modern choice for web: auto-waiting, built-in trace viewer, and Chromium, Firefox and WebKit from one API.

import { test, expect } from "@playwright/test";

test("user can sign in", async ({ page }) => {
  await page.goto("/login");
  await page.getByLabel("Email").fill(process.env.TEST_USER!);
  await page.getByLabel("Password").fill(process.env.TEST_PASS!);
  await page.getByRole("button", { name: "Sign in" }).click();
  await expect(page.getByRole("heading", { name: "Dashboard" })).toBeVisible();
});

Watch out for: there is no recorder-first workflow for non-coders, and someone must own the framework. Our Playwright interview questions and Selenium interview questions show what skills that takes.

• Which app types you need: web, mobile, API, Windows desktop, SAP.
• Who writes tests: coders, manual testers, or both.
• Where tests live: Git-friendly files, or inside the vendor's platform.
• How CI runs are set up and licensed.
• How locators and self-healing changes are reviewed.
• Test management and reporting links, for example Jira, TestRail or qTest.
• Security needs: SSO, audit logs, on-premises options.

1. Pick three real flows: one simple, one data-driven, one that has broken before.
2. Have one coder and one manual tester build each flow in the new tool.
3. Run them in your CI pipeline, not just on a laptop.
4. Change the UI slightly and see how much maintenance each test needs.
5. Write down what was hard, then compare with the same flows in Katalon.

Stay with Katalon if it already works and your pain is test design, not the tool. Move to TestComplete or Ranorex for deeper desktop support, to Testsigma or mabl for cloud authoring, to Tosca for enterprise apps, and to Playwright when your team can code and wants full control.
