Top 23 Free Usability Testing Tools for APP and Website Testing

Usability testing is a necessary step before websites and applications go live. When you launch a website or an app, you have no idea what your customers think of your landing page - whether they like it or not. Will it boost conversion rates? These are vital considerations that every developer has to pay close attention to.

Bad user experience may harm - or even kill - your customer base, so it is of utmost necessity to launch a usability test before going live. Usability testing allows designers or developers to discover problems before they are coded in order to improve the usability of the site and create a good user experience.

The Mockplus team has gathered the top 23 free usability testing tools that will help boost website usability.

Once you are done testing your prototype & have the code ready for it from your developers. It would be a good practice to check how well it renders when your website is accessed from different browsers. There is a very good possibility that your website may look different on different browsers, because every browser possesses a unique rendering engine responsible for interpreting your code. The process to validate browser compatibility is called cross browser testing, & if ignored, it may hamper the usability of your web applications.

We recommend using LambdaTest a cross browser testing tool on cloud which offers more than 2000 real browsers for both mobile & desktop web applications.
