[New Release] Katalon Studio v10.3.0 - July 2025

[Elly_Tran]

Hi everyone ,

We’re excited to announce the latest release of Katalon Studio — version 10.3.0 — packed with major enhancements, new capabilities, and user-friendly improvements! Explore the highlights below:

What’s New?

1. Web & API Testing

• Save API Response Bodies directly from the Response tab — click Save Response Body as File.

• View response headers in an organized table, with clearer display for large payloads.

2. Mobile Testing

• Mobile Self-Healing improves script resilience by automatically recovering from locator mismatches.

• Image-Based Locators are now available in Mobile Recorder and Spy — fall back to visual reference when needed.

3. Onboarding & UI Enhancements

• A redesigned Onboarding Experience introduces a Web Recorder-focused tour and a new Knowledge Hub for faster ramp-up

What’s Better?

• [Desktop Testing (Beta)] Windows Desktop app testing is back — no more WinAppDriver setup thanks to a built-in beta driver powered by FlaUI. Includes basic record, spy, and execution features

• [Reporting] Email reports get a fresh, modern UI template.

• [Recorder Plus] Enhancements for more reliable recording behaviors.

What’s Changed?

We’ve seen a few questions about how Katalon Studio works now — especially around free vs. paid versions — so let’s clear things up:

One Version Only	No more “Free” vs “Paid” download confusion — there’s just one Katalon Studio for everyone.

Katalon 10.3.1 just has been released, it mentions number of improvements for smart wait functionality, our scenarios take much much longer now to execute on 10.3.1 because smart wait takes ages waiting for everything, what we can do about that if it is not clear how smart wait functionality does?

Hi @mateusz.mysliwiec ,

Thank you for sharing your issue. Can you please help provide more information such as screenshot, video recording, steps to reproduce, your OS, browser version, … so that I can create a ticket for my team to investigate? Thank you

Hi @mateusz.mysliwiec and @kazurayam,

We’ve updated Smart Wait and Web keywords checking and waiting logic to improve test reliability. Please refer to this document for the changes before and after 10.3.0: Smart Wait in Katalon Studio version 10.3.0 vs Previous Versions

In addition, the default wait timeout has been reduced from 30s to 10s, and it can now be configured in Project Settings > Execution.

Hi guys,
I’m having a problem running Windows Driver using Custom. I have an application in Windows and it opens at the same time as ChromeDriver, which is why I use the Custom option. If I only use the Windows option, no error is thrown and the Windows application runs, but if I do the same thing using Custom, it doesn’t work
It was mentioned not to use DriverUrl because FlaUI opens automatically

I’m not sure if I understood correctly, but it seems that when running from custom mode, it tries to open WinDriver instead of FlaUI
