Katalon Studio 11 focuses on making test creation easier, smarter, and more reliable. This release upgrades the Web and Mobile Recorders, adds new AI-powered features for test creation and self-healing, improves diagnostics, and refreshes core frameworks for better security and compatibility.
Katalon Studio now includes an expanded MCP toolset with new WebUI testing and test data capabilities directly in Studio MCP Server. You can now orchestrate browser-based tests and manage internal test data more efficiently through MCP.
Why it matters: More MCP coverage means less custom code, better reuse, and easier integration with your existing DevOps and tooling ecosystem.
What's new
New MCP toolset for WebUI testing.
updateInternalTestData added to the Test Data MCP toolset.
getInternalTestDataDetails added for quick data inspection.
Expanded to 40 MCP tools in Studio MCP Server.
The new Web Recording Agent turns recording into an AI-assisted experience. You can describe test scenarios in natural language, and the recording agent converts them into clear test steps and test cases. The redesigned Web Recorder UI is simpler and more intuitive, especially for no-code/low-code users moving from manual testing to automation.
Why it matters: Teams get started faster, workflows are easier to follow, and less support is needed to adopt web test automation.
What’s new
AI API Test Generation now creates richer API tests from your OpenAPI specification. You choose the test types—Positive, Negative, Security, and Edge Cases—and Katalon Studio generates and runs the tests, then saves them to your Test Case repository for reuse. This runs via your configured StudioAssist AI provider, without depending on Katalon backend services, which better fits enterprise AI policies.
Why it matters: You can quickly go from no tests to broad API coverage in a few clicks, reducing the time and effort needed to build and maintain API tests.

AI Self-Healing helps keep your Web and Mobile tests stable when the UI changes. When a locator breaks, AI analyzes the page or app (including structure, screenshots, and attributes), finds the best-matching element, generates a new locator, and continues the test.
Why it matters: Test maintenance effort drops, flaky failures are reduced, and large test suites stay reliable as applications evolve.

Smart Mobile Recorder with interactive mode brings a web recorder–style experience to mobile testing. You interact directly with the app in a live device preview, and Studio automatically turns your taps, swipes, and inputs into test steps.
Why it matters: Mobile test creation becomes simpler and more visual, reducing the learning curve and speeding up mobile automation.
What’s new
StudioAssist Agent Profiles let you add reusable AI agents with custom system prompts and MCP server connections. These profiles can be shared across your team and projects, so everyone uses the same AI “copilots” for BDD, API, web, or mobile testing.
Why it matters: AI-generated tests become more consistent, you avoid repeating the same instructions, and teams spend less time on manual prompt setup.
What’s new
Katalon Studio Tracer is a diagnostic “flight recorder” for your tests. It captures a detailed view of each execution—actions, timing, screenshots, DOM snapshots, network logs, console logs, and more—and stores it in a trace file you can replay.
Why it matters: Debugging becomes faster and clearer, with step-by-step replay to see exactly what happened when a test failed.
Highlights
Katalon Studio 11 adds a new migration option: “Migrate from Studio 10.x to 11.x.” This helps you automatically upgrade existing projects to the new version, including Cucumber 3 to Cucumber 7 migration for BDD projects.
Why it matters: Teams can move to Studio 11 and the new frameworks faster, with less manual work and fewer migration errors.
Capabilities
Katalon Studio 11 updates its core frameworks to align with modern standards. The runtime now uses Java 21, with Cucumber upgraded from 3 to 7 for BDD users. Web and mobile testing are updated with Selenium 4.39, Appium Java Client 10.0.0, and Appium 3.
Why it matters: Enterprise teams can meet security requirements more easily and resolve many BDD and framework compatibility issues.
Capabilities
Katalon Studio 11 makes it easier to create, maintain, and debug tests with new Web and Mobile Recorders, AI API Test Generation, AI Self-Healing, StudioAssist Agent Profiles, and Katalon Studio Tracer. Combined with major framework upgrades, this release helps teams deliver more reliable automation across web, API, and mobile with less effort and faster results.
