    We compared numerous responsive testing tools, however, the efficient scroll sync in LT browser was a clear winner for us. The mirrored interactions allowed us to compare our website in a side by side view over numerous devices. The feature has been a time saver for us. Kudos to LambdaTest.


    Only 2 devices to test simultaneously in a single comparison view.

    LT browser has helped me save a lot of time on debugging my website for responsiveness. The convenience to view 2 devices emulated side by side with the option to debug using Developer tools has worked like a charm for me. Plus the integration to JIRA has been very productive for my team.

    LT Browser helps in making responsive testing process faster. It’s fairly easy to start using and you get the hang of it pretty fast. So not much of a learning curve involved and anyone from the team can start performing responsive testing from day one. Winning points are for primarily it’s UI is self explanatory and nice, switching devices is very easy with a good comparison view. Inbuilt dev tools can be really helpful as you can make changes on the go. However you can also take screenshots or video recordings and share it across with the team.


    Right now we can only see two devices side by side. Would be great if we can add multiple devices side by side.

    To test your website on multiple devices at the same time, it uses scroll-sync. Shares the performance statistics of your website with your colleagues and team. It employs network simulation to test webpages on low-latency networks.


    Would be appreciated if performance was obtained.
