Katalon Studio
All-in-one low-code platform for web, mobile, API, and desktop test automation.
Overview
Katalon Studio, launched in 2015, is a comprehensive test automation platform built on top of Selenium and Appium. It provides a dual-interface approach: a low-code GUI for beginners and a full scripting mode (Groovy/Java) for advanced users. Katalon Platform (the cloud offering) adds test management, orchestration, and AI-powered features like TrueTest (autonomous test generation) and StudioAssist (AI script generation).
Katalon is popular with mid-size organisations that want an integrated platform without assembling multiple open-source tools. In 2026, it competes directly with Tricentis Tosca at the low-code end and Playwright/Selenium at the code-based end.
What it's used for
Katalon is ideal when:
- One platform for all testing: Web, mobile, API, and desktop automation in a single tool.
- Mixed-skill teams: Business testers use the GUI; engineers write scripts in Groovy or Java.
- Quick start is critical: Pre-built project templates and object spy reduce setup time to hours.
- AI-assisted automation: TrueTest autonomously explores apps to generate test scenarios.
Pros & Cons

- AI features: TrueTest autonomous generation, StudioAssist code generation
- Strong reporting and analytics in Katalon Platform
Cons
- Expensive at scale: $175/user/month for premium features
- Groovy scripting is niche — most engineers prefer JavaScript/Python
- Heavy and resource-intensive compared to lightweight frameworks
- Vendor lock-in: proprietary project format and object repository
- Community smaller than Selenium/Playwright

NZ Context
Katalon is growing in NZ mid-market companies that want low-code automation without the enterprise price tag of Tosca. NZ IT training providers like IT Career Switch include Katalon in their QA bootcamps. For NZ teams evaluating low-code options, Katalon sits between free open-source tools and expensive enterprise platforms.
Alternatives
- Tosca — More powerful for SAP/enterprise apps but significantly more expensive.
- Playwright — Code-based, faster, and free. Better for technical teams.
- TestComplete — SmartBear's alternative with similar dual-mode approach.
