Chrome is currently the dominating browser with around 67.53% of market share as of Nov 2024, but if you only test your websites on Chrome, you are missing out on 32.47% of your users who visit your site on other browsers.
What if a bug occurs on those browsers? To ensure that no issues go undetected, you need cross-browser testing.
To test across browsers, you need a cross-browser testing tool. Without one, you'd have to manually switch between browsers, devices, and OSes for each test case.
In this article, we have listed the top cross-browser testing tools for your QA team. Choose a tool that fits your team's needs, resources, and technical expertise.
Benefits of Adopting a Cross-browser Testing Tool
Cross-browser testing is a part of cross-platform testing, which covers browser, OS, device, and legacy version combinations. The ecosystem includes:
- 9000+ devices
- 21 operating systems (including older versions)
- 6 major browser engines powering thousands of browsers
With a cross-browser testing tool, you gain:
- Better coverage across thousands of environments.
- Time and cost savings vs maintaining an in-house device lab.
- Parallel execution to speed up regression testing.
- CI/CD integration (Jenkins, GitLab, Azure) for automated quality checks.

2. Selenium [Best Framework For Cross-browser Testing]
Selenium is a go-to framework for cross-browser testing due to its flexibility and extensive support. It works with multiple programming languages such as Java, Python, C#, Ruby, and JavaScript.
With support for major browsers like Chrome, Firefox, Safari, and Internet Explorer, Selenium WebDriver allows seamless execution of tests across browsers.
In terms of cross-browser execution:
- WebDriver supports Chrome, Firefox, Safari, Edge, and IE via browser-specific drivers.
- Tests can be written in Java, Python, C#, JavaScript, Ruby, and more.
- Tests can run locally, via Selenium Grid, or on cloud-based platforms.
However, Selenium has some drawbacks:
- Each browser requires its own WebDriver (chromedriver, geckodriver, etc.) and must be updated frequently.
- Browser updates can suddenly break your tests.
- Setting up and maintaining Selenium Grid is complex.
