If your team builds complex software that people depend on, you need testing tools you can depend on. That’s Squish.

Modern Approach to UI Test Automation 

Two decades of innovation. One clear mission: delivering reliable, intelligent UI automation that grows with your technology.

Twenty years ago, Squish was developed with a simple but powerful goal:

Build the first GUI test automation tool that speaks the language of real applications.

The result was Squish GUI Tester—a platform designed not just to simulate clicks or test pixels, but to truly understand the underlying UI structure of complex applications across Qt, Java, Windows, and embedded systems.

Since then, Squish has set the standard for professional GUI test automation, trusted by over 3,000 customers worldwide across industries like aerospace, medical, automotive, industrial automation, and finance, where software quality and compliance are non-negotiable.

Today, as part of The Qt Group, Squish continues to lead the future of quality assurance, combining deep industry expertise with next-generation automation technologies, seamless platform integration, and continuous testing solutions.

The Problem We Solve

We’ve seen too many QA teams struggle with:

  • Fragile, high-maintenance tests that collapse under UI changes and OS updates

  • Fragmented tools that can’t handle cross-platform applications

  • Automation suites that can’t keep up with evolving UI frameworks

Squish is built differently.

It’s a powerful, object-driven platform, not a browser extension or patchwork tool. Squish provides deep toolkit integration, true cross-platform automation, and seamless CI/CD compatibility.

Start cutting testing costs and deploying faster!

Squish is designed to help you  reduce risk, increase release velocity, and scale quality without scaling headcount.
