Katalon Scout - Explore, test, and deliver at the speed of AI.

TRY NOW

What problem it solves:
Developers and small teams lack time, QA resources, and simple tools for early-stage bug detection. Most exploratory testing tools are complex, expensive, or require test scripting.

Our solution
Katalon Scout is a standalone AI-powered testing tool that autonomously explores web applications — identifying functional issues, broken links, UI bugs, and boundary errors — without needing any test case setup. It’s a “kick-and-wait” blackbox solution designed for developers who want results, not process.

Core Features

• Zero setup: Just enter a URL — no scripts, no configuration
• AI-driven analysis: Detects bugs, anomalies, 404s, accessibility issues
• Scoring & insights: Instant feedback with improvement scores and fix suggestions
• CLI support: Dev-friendly terminal use & localhost testing
• Quick fix tips: Actionable recommendations tied to each bug
• Session history: Track your quality improvements over time

Who it’s for:

1. Developers who want to validate their work before handing it off
2. Tech leads at startups or teams without QA
3. Eventually, testers seeking boundary, accessibility, or security validation

Why We Built Katalon Scout: "Send a Scout" to Test the Vibe Before QA

In the world of software development, a seismic shift is underway. AI is no longer just a futuristic concept; it's in our IDEs, acting as a pair programmer, and generating code at a velocity we've never seen before. This explosion in development speed is incredible, but it comes with a new, unspoken challenge: the sheer volume of this "vibe code" is overwhelming traditional quality gates.

This is precisely why we built Katalon Scout. We believe that in the age of AI, you need to "send a scout" to check for trouble before you commit your team's most valuable resource—the deep, critical thinking of your QA professionals.

The old model is straining at the seams. Developers, empowered by AI assistants, are pushing more features and code than ever. But this rapid-fire generation means that subtle flaws and awkward user flows—the very things that kill an application's "vibe"—are multiplying faster than manual testing can catch them. Waiting for the formal QA cycle to find these issues creates a bottleneck—a bottleneck that directly impacts our target audience: high-velocity development teams and small businesses trying to innovate quickly.

For developers in these environments, it means their code sits in a queue, forcing them into painful context-switching when bugs are eventually found. For the organization, it nullifies the speed advantage gained from AI-driven development, slowing the entire delivery pipeline down to the pace of this final quality gate.

The New Imperative: Send a Scout First

This is where Katalon Scout comes in. It's your autonomous agent, your digital scout, sent to the front lines of your application to perform reconnaissance. It intelligently explores your app, identifies hazards, and reports back with findings before you commit your human experts.

Think of it as a crucial pre-flight check. Scout's AI doesn't need test scripts. You give it a URL, and it autonomously explores your application to uncover the issues that often slip through in this high-velocity world:

Unconventional User Journeys: It probes the unexpected paths that users inevitably find but are rarely documented.

Glaring UI/UX Gaps: It identifies visual inconsistencies and usability hiccups that disrupt the user experience.

Hidden Functional Flaws: It autonomously discovers broken links, unhandled errors, and other show-stopping bugs that can hide in the vast sea of new code.

A Tool for the Entire Software Team

We designed Scout to be a powerful ally for any team structure, fostering collaboration between developers and QA.

For teams with a dedicated QA process: Scout acts as a collaborative "first look." Developers can "send a scout" to catch initial bugs and smooth out the user flow, ensuring that what they hand over to QA is already in a much better state. This frees up QA professionals from the repetitive task of finding obvious flaws, allowing them to focus their deep expertise on more complex, strategic, and high-impact testing. Scout also tirelessly covers the broad, exploratory ground that busy QA schedules often don't permit, adding another layer of quality.

For teams without dedicated QA: In small teams where developers wear many hats, Scout provides an essential safety net. It acts as an automated "first user," offering a critical baseline of quality and user experience testing before an application is released to the public.

The Long Run: Bridging the "Vibe" Team with the QA Team

Our vision for Scout extends far beyond its initial exploratory capabilities. In the long run, Katalon Scout will integrate deeply back into the Katalon platform umbrella. The insights and issues it uncovers today will become the foundation for the automated tests of tomorrow.

Imagine this: Scout explores your application and finds a critical bug in a user flow. In the future, it won't just report it. It will offer to generate an executable, automated test script based on its findings. Then you can just re-execute the test or even schedule it for frequent check.

This is how we bridge the gap. We start by bringing a "vibe test" to the developer's workflow—the "vibe" team. Then, we provide a seamless path to bring the rigor and discipline of the QA team into that flow. Katalon Scout is the connection, ensuring that the speed of AI-driven development is matched by the confidence of robust quality assurance.

We're in Beta, and Your Feedback is Our North Star

The challenge of ensuring quality in the age of AI is a new frontier for all of us. Katalon Scout is our answer, but we know it's just the beginning. The current version is in beta, and we are counting on the community to help us shape its future. Your feedback, your critiques, and your ideas are essential.

We invite you to "send a scout" on your own applications and join us in defining the future of testing—a future where every application not only works flawlessly but also has that essential, intuitive vibe that users love.
