Cross-browser testing is a critical aspect of web application quality assurance. With numerous browsers and constant updates, thoroughly testing web apps across browsers helps ensure a consistent user experience and identify bugs specific to certain browsers.

Comprehensive cross-browser testing is essential to deliver a seamless experience for end users on the browsers and devices they prefer. However, manually testing web applications across multiple browsers is highly time-consuming. Many robust tools are available to assist with automated and manual cross-browser testing. These tools help streamline validation across browsers by reducing the effort required to configure and execute tests.

Top 12 Cross-Browser Testing Tools

There are both open-source and commercial solutions to evaluate that optimize the cross-browser testing process.

Here are three of the best cross-browser testing tools to consider leveraging:



TestSigma is an intelligent automation platform that makes cross-browser testing seamless. It supports automated testing across 2000+ real browser and OS combinations. TestSigma’s smart test recorder generates scripts while you manually test. These scripts can then be augmented and executed across browsers and devices in parallel. The platform identifies and adapts scripts for dynamic elements. TestSigma also enables manual live testing on real mobile and desktop browsers. Robust reporting provides insights into cross-browser coverage and pass rates.



LambdaTest is a cloud-based cross-browser testing platform. It allows manual and automated browser tests on a scalable, online selenium grid.
