QA Architect at a tech services company with 51-200 employees
Provides efficient test automation for web applications and has good technical support services
The platform's most valuable features include its recorder, which allows users to create test cases with minimal effort, significantly simplifying the process. Vision AI enhances image recognition capabilities, improving the accuracy and efficiency of visual testing. The audit trail feature helps track changes and maintain compliance, which is particularly important in regulated industries. Smart fix automatically resolves issues, reducing manual intervention, while the self-healing feature ensures that test cases remain accurate and functional, even when system changes occur.

Practice Specialist at a government with 1-10 employees
Cloud-based testing has simplified remote mobile validation and provides flexible device coverage
I was not impressed with how detailed their analytics and logs are from LambdaTest. The solution we were testing is being used because many of us are working from home. It was easy to implement because with a real phone, we have to bring a real phone to each person. Since three years ago, many employees have been working from home, so we were trying to find a solution for this challenge. We had no need to exploit the information for the analytics generated in the background. The purpose was simply to make it easy for our employees to access a phone. The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers. The contrast on a real iPhone provides better contrast than with the cloud solution. The only aspect that was less favorable than on a real phone was the contrast of the color.
