    One day, I needed to test a specific issue that was occurring only on Pixel phones. I turned to LambdaTest, quickly identified the problem, and was able to fix it. There hasn't been a situation where I felt LambdaTest didn't help, it's my go-to solution for testing, as it solves many problems.

    • More real devices should be added like I have Samsung mobile but it was not in the list
    • It takes time in checking the link on LambdaTest if we compare with real mobiles
    • Sometimes exact results are not matching as from real mobiles

    The reason i have given the 10 points becasue the problem LambdaTest solves is providing access to all devices in one place, allowing developers to identify the same errors they would encounter on real devices. This makes life much easier, especially for developers who regularly face cross-device functionality issues. It's a big plus point that positions LambdaTest as an all-in-one solution.

    Because of the ease of use of the platform, we just save a lot of time and effort with this as its a feature rich solution, we just need to upload app binary once and for everytime we need to test on a different device we can just directly install that binary on the device without the pain of reupload.

    The customer support team is very active and cooperative. Once, I contacted them in their off timings because of an issue, I got an instant reply from the executive and he resolved the issue very efficiently. This is why we have been using LambdaTest for more than two years. It is best suited for us.

    While BrowserStack is also a well-established platform, we found LambdaTest to offer similar and even better features at reasonable pricing. LambdaTest is more cost-effective than BrowserStack. LambdaTest provides a free forever plan, while BrowserStack does not. Even manual testing plans are better priced than BrowserStack’s. In terms of UI and onboarding, we found LambdaTest more user-friendly as well.

    • Automation testing has a bit of a learning curve
    • Lack of real device keep that bug in your head if not on the website.
    • Need to wait for a while for a new OS or browser version on the contrary of immediate availability in case of owning a lab
