It fulfills everything from automation to manual performance
The most valuable features of the product are the performance parameters it gives us, as well as the seamless connectivity with our automation suites. I am also pleased with the continuous enhancements made to HeadSpin. There have been many features added since we started using the product, and all of them are useful.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature is that this is the first connected intelligence all-in-one platform."
"The technical support is really helpful because we can set up direct calls with them if we want to. We can use Zoom or Google Meet to interact with them directly, and if there is an issue in our system, they will help us by reproducing the issue in their machines and trying to figure out a solution. The support is really smooth, and we like that they're very supportive."
"HeadSpin allowed us to manage remote work during Covid, enable continuous automation execution, and facilitate collaboration between various departments (product managers, developers, etc..)"
"The initial setup of HeadSpin was very easy and user-friendly, and it was easy to configure and write a script to achieve the desired outcome."
"Large companies and enterprises are using this product."
"The most valuable feature of HeadSpin it's the integration with other solutions; it is great, and I can search for an element or do a quick debugging on the application right on HeadSpin, which is very useful."
"It has an interesting feature called AV box testing. A lot of companies that are in the OTT segment don't really understand what their streaming is like. They can't test for streaming quality. There are restrictions where you cannot simulate live streaming. For example, on Netflix, you can't simulate how a movie is being streamed on a remote device. That's why HeadSpin has got this AV box testing feature. It is a patented feature. They send an AV box to your location, and you can test live streaming, which is something that no other company does."
"The most valuable features of the product are the performance parameters it gives us."
"LambdaTest proved to be a savior for us here, as one platform does the job!"
"It is a scalable solution."
"The technical support services are excellent."
"Without a doubt, LambdaTest is one of the big reasons behind our faster deployment and better team collaboration."
"Builds that took days to complete with in-house infrastructure were executed in a couple of hours."
"LambdaTest easily integrates with leading project management, bug tracking, and CI-CD tools like Jira, Asana, Jenkins, Circle CI, and more."
"The most valuable feature is the real-time testing, which helps you to test your website on more than two thousand combinations of browsers and operating systems."
"LambdaTest has helped me gain more customers."
 

Cons

"Support and pricing could be improved."
"If you want to do some testing or check the devices manually or check the application in a particular device manually, it is really laggy. That's a disappointment because sometimes we would like to do manual testing when our local devices are not available."
"Sometimes, devices go offline and some features are not functioning on some devices, specifically on iOS."
"They should automate their onboarding. A lot of things are still manual. They can create a video assistant or something like that to completely automate the entire process."
"HeadSpin needs to improve the hardware. With the mobile, the battery life reduces and must be continuously charged."
"There is a great scope to improve professional services; the time to deploy is quite long, and while they can set up automation through scripts at this stage, they are very expensive."
"HeadSpin could improve on the user interface because it is very poor."
"HeadSpin could improve on the user interface because it is very poor. The checks that are done on the iOS devices are very difficult, but for Android, it runs great. For all iOS devices, the user interface and how it interacts with the device are very poor."
"LambdaTest's technical support comes in different tiers - most issues get resolved, but there's room for improvement with critical issues."
"Mobile application testing will be an added benefit for us if LambdaTest implements this really soon."
"I feel that the automated screenshot testing takes a little longer on MacOS sometimes."
"Load flow compared to other stacks needs improvement."
"Their smart testing module needs improvement."
"It would be nice to have an API for visual regression testing."
"Performing automation testing from UI is a little slow and could be improved."
"We get logged out of the devices if there is some inactivity."
 

Pricing and Cost Advice

"It has a yearly license. There is no other option. It is expensive. There are a lot of other cheaper players in the market, but it is like a Mercedes. You pay an extra premium for it, but you get the benefits. I would love to see them come up with project-based costing. Companies that are low on funds or new-age can do with pricing that is easily digestible. They can give them a pricing model for three months. They can provide a startup package."
"It's not cheap, but there are a few different packages and different prices for enterprises with different product versions."
"I believe the licensing cost is cheap because it's a total solution, hardware, license and software."
"We have a yearly license for 16 devices."
"The pricing could be made cheaper."
"The product can be described as an averagely-priced solution."
"I used the product for free."
"LambdaTest is priced well, which is why we migrated to it."
"It is free to start, which means you can actually see how it works and then take the decision to buy."
"LambdaTest's pricing is cheaper than that of other similar platforms."
"LambdaTest is on the cloud, offers both free and paid plans which start at $19 USD per month."
"The pricing for LambdaTest is affordable, and one of the reasons we implemented it."
