Review Summary
Generated using AI from real user reviews
LambdaTest receives overwhelmingly positive feedback, with the vast majority of recent reviews rating it 5 stars and praising its core strengths in cross-browser testing and parallel execution speed.
Users consistently highlight three major benefits. First, parallel testing significantly reduces execution time—reviewers report cutting test cycles from 50 minutes to 10 minutes, or full builds from days to hours. Second, the platform's browser and device coverage is extensive (2000+ browsers cited) with fast updates to latest versions. Third, infrastructure management is handled, eliminating the burden of maintaining local test machines while supporting local app testing via tunneling features. Integration with CI/CD tools like Jenkins, CircleCI, and GitLab, plus project management platforms like Jira and Slack, is widely appreciated.
The support experience and pricing compared to competitors like SauceLabs and BrowserStack are frequently mentioned as deciding factors. Users describe 24/7 support as responsive and solution-focused. Several reviewers switched from BrowserStack or SauceLabs specifically citing cost savings.
Minor criticisms are rare but exist: a few users mention wanting native mobile app testing beyond web simulators, and one requests more device options for screenshot testing. Overall, the negative feedback is negligible relative to the consistent praise for speed, coverage, ease of use, and value.

“LambdaTest’s Smart Testing helped us identify Visual Regression bugs! While…”
LambdaTest’s Smart Testing helped us identify Visual Regression bugs! While we develop our web applications, our top concern was to verify the unintentional changes to the application's visuals. We need to make sure that changing one component doesn't break the styling of another component. LambdaTest's Smart testing helped us to identify visual regression bugs for every new build. We could capture our website screenshots belonging to different environments i.e stage and production & upload them on the Visual Testing platform. We were able to discover visual deviations with pixel to pixel comparison by capturing screenshots, comparing them against the baseline image, and highlighting visual changes. The slider mode is very helpful to compare the visual discrepancies between the two images by toggling them. Overall, Smart testing helped us perform reliable visual testing at scale and eliminated the risk of delivering visual bugs.

LambdaTest has optimized our Selenium Testing experience to deliver a seamless user experience across every browser and device. With its cloud Selenium Grid, we were able to run our test cases concurrently across thousands of desktop and mobile browsers. It helped us to reduce our test suite's build execution time by over 10x with parallel testing. We don't need to worry about updating versions, adding devices, maintaining device sanity anymore. We have been able to easily automate and continuously run all of our test cases through the CI pipeline on LambdaTest's reliable cloud infrastructure. We even use the Lambda tunnel to test our local web apps before the final web launch. The integration with Jenkins CI helped us to accelerate and deploy our quality builds faster.

“To be honest we were skeptical for any cloud infrastructure…”
To be honest we were skeptical for any cloud infrastructure to be able to serve our needs of flexibility, browser coverage and quick responses we benchmarked for our existing agile pipelines. But LambdaTest has been featureful and proactive enough to keep the confidence in their cloud infrastructure. I have been seeing it for quite some time that they get us the latest desktop and mobile browsers to test on within 2 week and they are getting faster with it. We specifically wanted more machines with a specific browser configuration and they quickly acted upon our request, moreover an easy integration with Monday helped us in quickly resolving the bugs encountered as we hate long mail trails. It is been 10 months we are using LambdaTest and it took over all our testing needs faster than I expected

“As technology advances, enterprises are switching from manual testing to…”
As technology advances, enterprises are switching from manual testing to Selenium Test Automation. But one area most enterprises are still struggling is with the scalability of running several tests in parallel. LambdaTest has been a boon for us when it comes to Selenium automation. With a Selenium Grid based on the cloud, we don't need to stress about setting up and maintaining infrastructure anymore. We can run hundreds of tests in parallel on 2000+ browsers and OS versions running on real machines. LambdaTest really helped us in reducing our web testing cost and at the same time scale it as and when required. To leverage on marketing campaigns, we needed to ensure all our deliverables render seamlessly on different mobile and desktop browsers our users use to view them from across the world. The geolocation testing functionality helped us set the location and test our website over various locations. At LambdaTest, we can now run geolocation testing to test our website across 40+ countries. The pricing plan is pretty simple and easy to grasp, with no hidden costs at all.

“Our overall test execution time for every release was very…”
Our overall test execution time for every release was very high, since we shifted to remote working. We had to find a solution that would help us radically reduce our test execution time and help us with faster deployments. Moreover our UI had multiple API dependencies which prompted us to leverage browser automation testing. By running tests in parallel on the lambdatest platform we reduced our testing time from 50 minutes to 10 minutes. This really helped the team in getting faster feedback, in a better way using LambdaTest integrations and put more focus on code quality.

“Using LambdaTest we could run all our functionality tests across…”
Using LambdaTest we could run all our functionality tests across various browsers, OS, and resolutions. We have a significantly large user base with some users accessing the product through browsers like Internet Explorer. LambdaTest was a big help to test over those rare combinations of browsers and OS. W could find UI misalignments and browser compatibility issues faster than before. Especially test automation helped us bring down the time, effort, and cost of our deployment. Thanks to the support team for being available 24*7, and solving rare hiccups, then and there.

LambdaTest is brilliant. The ease of testing locally hosted URLs over hundreds of browsers & operating systems without worrying about infrastructure issues has led us to deliver better softwares, faster! Using LambdaTest Selenium Grid, we have radically reduced the manual testing effort while ensuring our web application's cross-browser compatibility. It's crucial for us (as a healthcare provider) to make sure that there are no errors. We had to incorporate a lot of changes due to COVID-19 and our in-house infrastructure plateaued the testing cycles, delaying our go-to-market. That’s where LambdaTest came to pull us through. Leveraging LambdaTest cloud infrastructure, we could scale our automation test cycles without much of a struggle. Our automation team could execute Selenium scripts in their preferred language, and the ability to test parallely helped us optimize our continuous deployment. Thanks to LambdaTest, we can find more critical bugs with less manual testing efforts.

“We have been using LambdaTest for almost 6 months now.…”
We have been using LambdaTest for almost 6 months now. Back then, we were thinking of implementing shift left testing to catch bugs ASAP. With browser testing being one of the most rigorous and time-consuming validations, we were looking for a solution that could help us achieve continuous testing through our GitLab CI/CD pipeline. That is when we landed over a webinar of LambdaTest which demonstrated setting up GitLab CI/CD and integrating it with their cloud. We thought of giving the integration a go and it worked like a charm. We were able to leverage the Git based triggers to execute our CI/CD pipeline. So every time a new commit was pushed from our end, the pipeline ran an automated build over the LambdaTest Grid, which allowed us to ensure our UI on every major and minor release with access to numerous browsers, platforms and devices. Integrating LambdaTest in our GitLab CI/CD pipeline allowed us to deploy quality builds faster. In the new normal where companies are forced to perform remote testing due to COVID-19, a cloud based solution like LambdaTest has been a life-savour. It gives us the flexibility to run tests from anywhere at any time without being bothered about maintaining an inhouse infrastructure.
