Can I use my existing Selenium, Appium, or Playwright tests?

Yes. Katalon Studio is built on Selenium and Appium, so existing scripts work. TestOps also ingests Playwright results for unified reporting and analysis.

How does Katalon AI help?

AI generates test cases, self-heals locators when the UI changes, explains failures in plain language, and can execute multi-step workflows from coding agents via the MCP server.

Is there a free trial?

Yes. You can start a free trial with no credit card required and begin running tests immediately.

What is the Katalon MCP server?

The Model Context Protocol server allows external AI coding agents (like Copilot, Cursor, Claude) to directly drive Katalon's test execution, results posting, and other workflows.

How does self-healing work technically?

When a UI element's locator changes, Katalon AI uses object repository heuristics and machine learning to automatically generate a new locator and update the test step for you to review.

Can I use my own AI provider keys?

Yes. While Katalon provides a built-in AI service, admins can configure the platform to use their own keys for supported providers like OpenAI, Azure OpenAI, Google Gemini, or AWS Bedrock.

Katalon

Katalon True Platform is an integrated system for modern software testing, combining a test automation IDE (Katalon Studio), test management (TestOps), cloud execution (TestCloud), and production insights (TrueTest). It enables QA teams to author, execute, and manage tests across web, mobile, API, and desktop applications using no-code, low-code, or full-code approaches. Built-in AI agents assist with test generation, self-healing, and failure analysis, while the MCP server allows integration with external coding agents like Copilot and Cursor. Targeted at QA engineers, testers, and DevOps teams, the platform aims to centralize the testing lifecycle on a single system of record. It supports Playwright scripts alongside its native testing engine and offers extensive integrations with CI/CD pipelines and project trackers.

Product information

Everything worth knowing about Katalon

The complete picture — from everyday features to the technical detail builders and IT folks dig for.

Core features

What it actually does

Agentic Test Automation IDE

Author web, mobile, API, and desktop tests with no-code, low-code, or full-code in a single environment. Katalon AI agents generate and explain tests in plain language.

Centralized Test Management & Manual Testing

Plan cycles, track coverage, and gate releases on one shared report. Manages requirements, test cases, evidence, and defects for an auditable quality record.

Cloud Test Execution

Run test suites in parallel on real browsers and devices via TestCloud, or on your own CI runners with Runtime Engine.

Production Insights & Test Generation

TrueTest observes real users in production, maps journeys against regression coverage, highlights gaps, and auto-generates missing tests.

Technical capabilities

AI-Powered Test Generation & Self-Healing

Generate test cases from requirements or tickets, and heal broken locators when the app changes to maintain test stability.

MCP Server Integration

Connect the Katalon platform directly to your own AI coding agents (like Copilot, Claude, Codex) to drive testing workflows.

Playwright + Katalon: Run Tests at Scale, One Report for All

Playwright is genuinely great at web UI automation. We think so too - that's exactly why we're not trying to replace it. We're making it better 💡 In this video, Alex Martins (VP & Head of Product Marketing at Katalon) breaks down how Katalon True Platform takes your existing Playwright specs, unchanged, and gives them what scale actually requires: ✔️ Cloud execution across browsers ✔️ One report that covers Playwright plus every other test type ✔️ Traceability back to requirements ✔️ AI agents working from the platform, your IDE, or your coding environment Curious what that looks like in practice? Join Alex live on September 16 for our webinar "Bring Playwright Into Katalon": https://katalon.com/webinars/bring-playwright-into-katalon #Katalon #Playwright #TestAutomation #QualityEngineering #SoftwareTesting

Who uses it

Real use cases, no hype

End-to-End Test Automation

Author and maintain automated tests across web, mobile, API, and desktop applications from a single platform.

AI-Assisted Test Authoring

Generate test cases from requirements, Jira tickets, or plain language prompts using built-in AI agents.

Unified Test Management

Centralize manual and automated test cases, runs, and release evidence for complete traceability.

Cross-Platform Cloud Execution

Run test suites in parallel on real browsers and devices via TestCloud for rapid feedback.

Production Quality Monitoring

Observe real user journeys in production to identify coverage gaps and auto-generate missing tests.

Playwright Test Scaling

Execute and analyze Playwright tests at scale in the cloud with integrated reporting and AI insights.

Enterprise-Grade Governance

Implement role-based access, audit logs, and SSO/SCIM for compliance in regulated industries.

What's great

All-in-one platform: authoring, management, execution, insights.
Powerful AI agents for test generation, failure analysis, and self-healing.
Broad testing scope: Web, mobile, API, and desktop from a single IDE.
Seamless integration with Playwright, Selenium, and Appium ecosystems.

Technical strengths

Enterprise-grade security controls (SOC 2 Type II, SSO, SCIM).
MCP server enables driving tests from external coding agents (Copilot, Cursor, etc.).
Agentic testing model with unified AI orchestration across all four tools.

Where it falls short

High cost at scale, especially for True Automation seats.
Can feel like a 'black box' with proprietary AI and closed-loop features.
Steeper learning curve for advanced features beyond no-code.
Advanced features (TrueTest, private SaaS) require enterprise sales and custom pricing.

Technical limitations

Pricing model becomes complex with add-ons for execution and mobile.
Native integration with Playwright is powerful but adds another abstraction layer.
Dependency on Katalon's own cloud (TestCloud) for optimal scale, though on-prem is possible.
