Like

Using remote servers and connections for running the automation tests is a good feature and helps in eliminating local configs leading to different outputs/errors.

Like

LambdaTest SmartUI is a game-changer in the UI testing world. This tool gives options for many project types such as webhook testing, CLI testing, Figma testing, PDF testing, and more. It has many features that make UI testing easy and smooth. You can test on multiple browsers and their viewports in a single run. It also supports across all versions of selenium. Before using SmartUI, I had to use many different tools, but now everything is available in one place. The layout feature is great as it checks the structure and placement of UI elements, not their content or styling. Also, the figma design to live website comparison is an excellent idea and this feature is only is only available in LambdaTest. Integration is very simple, as it can connect with almost any tool, and the UI is easy to use. I would recommend every QA to try this tool for their testing needs.

Dislike

1. Can be more cost effective - giving users packages with more users for the same account at the same time usage 2. We have test logs, which are the earlier tested history - for which if we can have browse and reuse the test logs option like web browser history usage - click and go to the respective used page, it would be very helpful. 3. Smart comparison page is not showing up the images properly - baseline image section and comparison image section Mobile Testing limitations 5. Limited Free tire

Dislike

Proper setup steps and submission details are challenging to understand which can be improved.

Dislike

When running multiple URLs together, sometimes a few screenshots are not captured, and the SmartIgnore feature needs improvement. Apart from that, all my cases were fulfilled using this tool.

    Integral part of our flows and CI/CD pipelines

    Nov 14, 2025
    Because of our setup and configuration, LambdaTest was a bit difficult to setup and the issues do not always translate to a clear explanation what it is that's going wrong. But once everything is setup it's a smooth ride and a lot of very interesting functionalities that helps our teams understand why certain tests are failing. An extra rating star because LambdaTest always seems willing to help us out with whatever might be going wrong and most of them are very capable.
