Top 20 Essential Website Testing Tools

Website testing is a critical stage in the development cycle that ensures websites to function flawlessly on every platform, device, and browser. It identifies bugs, usability problems, and security vulnerabilities before they hit the end user.

QA teams and developers have all they need to develop secure, user-friendly, and high-performance websites with this set of 20 extremely well-curated tools.

What are Website Testing Tools?

Tools for website testing are computer programs used to test some or all properties of a site—function, performance, appearance, UI/UX, and security. They ensure that websites work as designed on different browsers, devices, and operating systems.

Web test tools are an invaluable asset in improving the quality and reliability of software. They replace manual efforts, remove human mistakes from manual testing, and speed up the identification and correction of bugs, thus improving QA procedures to be more accurate and efficient.

1. Selenium

Selenium is a popular open-source test automation framework for web applications on a variety of browsers and operating systems. It mimics the actual user activity to confirm web functionality.
