UserTesting helps UX researchers, designers, product teams, and marketers gather actionable insights through research, testing, and feedback. With a network of real people ready to share their perspectives, UserTesting enables organizations to make customer-first decisions at scale.
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.
UserTesting has been great for moderated customer interviews/usability testing as well as for unmoderated testing of messaging, imagery, prototypes and live experiences. I would say that the scope of what you want needs to be limited, as the participants are only paid so much and tests are supposed to not exceed a certain amount of time. For customer interviews, I think it can be difficult to onboard customers to UserTesting if they have never used it before. If I set up interviews, I don't even have them use the UserTesting scheduling tool, I actually set up all the interviews with the customers myself through the tool (being mindful of time zones!). When we run the meeting, they really don't even know UserTesting is involved. Might be nice for UserTesting to allow the upload/connecting to of a Zoom interview and let it do the transcription/analysis from there.
Sometimes there are restrictions around types of research that can be used for moderated user-testing with our own users.
For tests on relatively small areas of a website or app, the AI analysis seems rather overblown, like it's trying too hard to come up with something insightful when the test is actually about something quite small (e.g. structure of a mobile app menu).
It's difficult to invite our own users to unmoderated user-testing because they wouldn't know how the UserTesting interface works - this is particularly an issue for mobile research.
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.
I'm very happy with my experience of the product and the level of service and learning resources they provide. If the service becomes more expensive than it currently is then we might not be able to justify additional cost - but this is theoretical. I would recommend UserTesting and would ideally renew our contract.
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.
It's very good, I have used other tools in the past and this is by far the most intuitive and user friendly. Testament to this is the ease with which other non researchers who have been onboarded to the tool with our additional seat have found it easy to use
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.
I have contacted UserTesting's customer service online, by email, or by phone a few times, and each time, I have encountered the same professionalism and expertise. Even in person during a work event, they were there, and it was the same experience.
From a technical perspective, the implementation was extremely smooth. Most of the change management / implementation hurdles were clearing use of the tool through our various security, legal, and information privacy teams. Once these concerns were addressed (UserTesting.com was very helpful in providing all the needed documentation), the implementation process was very simple and we were able to get going right away.
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.
The quality of the participants: they usually have good feedback and act like "professional" users. Which is good when we want a few insights in a short amount of time. Also, the interface is good. I miss having more features, like a good transcription tool like we have in Condens
