TestMu AI (Formerly LambdaTest)Reviews of testmuai.com

I used their mac app to test website in different mobile devices. It worked amazingly well, was able to see the responsiveness of the website in multiple devices at once, saved lot of time to do it in actual devices and more accurate than browser’s inspect view for different resolutions.

I’m genuinely disappointed with my experience using LambdaTest. I canceled my subscription last year right after receiving the invoice, so I was very surprised to be charged again this year. When I tried canceling today, the process was extremely confusing and required clicking through multiple unnecessary steps. Even after receiving a “cancellation successful” message, the subscription still appeared as active under “Recurring Products.” I had to go through the entire procedure a second time before it finally showed as canceled. I contacted support and was told my subscription “is set to cancel,” but the unclear interface and redundant steps made the whole experience frustrating and time-consuming. Based on this, I cannot recommend LambdaTest. A cancellation process should be transparent and straightforward — this one isn’t.

I was looking for a tool that could manage parallel test execution for my small QA team and this one worked out really well.

The main issue is the speed. Launching a VM for real-time testing takes forever, and once you are actually in a session, the input lag is unbearable—especially on iOS simulators. I’m clicking a button and waiting 3-4 seconds for a response. It makes debugging responsive design issues impossible. Worse, their local tunnel (UnderPass) is incredibly unstable. It disconnects randomly in the middle of automated CI/CD pipelines, causing false negatives that waste hours of our developers' time. We've reached out to support three times this week, and every time we get a generic copy-paste response asking us to "check our firewall settings" or "clear browser cache," completely ignoring the logs we sent. We are cancelling our subscription and moving back to BrowserStack. You get what you pay for.

Best tool for tesrting website and Application. From now, no need to purchase any real devices as this tool provide in all of them. Thank you team.

Lambdatest proved super useful to us. We were easily able to test and resolve our production issue affecting our customers on Safari for iOS. Testing using this tool felt like a breeze, better than a real hardware. We are using lambdatest's MCP servers as well that makes it super easy for the agentic llms we use to integrate and generate configs!

I found LambdaTest to be a very useful platform for cross-browser testing. It allowed me to test my application on multiple browsers and devices without setting up anything locally. The automation setup with Selenium was smooth, and the reporting with screenshots and video logs made debugging easy. I liked how it integrates with CI/CD tools like Jenkins and GitHub, which helps in continuous testing. The dashboard is user-friendly and provides clear insights. Sometimes it feels a bit slow depending on internet speed, but overall, it saves a lot of time and effort compared to maintaining local test environments.

It is a excellent tool, smooth, fast, and provides accurate results. The UI is very easy to use.
