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 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."
"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."
"HeadSpin is highly advanced; it has got all the performance structures to provide visibility into how my app is performing in the real world and helps to identify the gaps."
"Large companies and enterprises are using this product."
"HeadSpin allowed us to manage remote work during Covid, enable continuous automation execution, and facilitate collaboration between various departments (product managers, developers, etc..)"
"The most valuable features of the product are the performance parameters it gives us."
"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."
"The support docs are precise and you can get started with them easily."
"LambdaTest Selenium Grid has helped us radically reduce the manual testing effort and ensure browser compatibility."
"We use the solution for automation testing and monitoring."
"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."
"The real devices feature is the most valuable feature for us."
"This product offers out-of-the-box geolocation testing in automation, which is amazing!"
"LambdaTest is easy to use, and the documentation provides all the needed information."
 

Cons

"Sometimes, devices go offline and some features are not functioning on some devices, specifically on iOS."
"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."
"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."
"HeadSpin needs to improve the hardware. With the mobile, the battery life reduces and must be continuously charged."
"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."
"Support and pricing could be improved."
"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."
"It would be nice to have an API for visual regression testing."
"Sometimes, when multiple users use the tool simultaneously, it can slow down, affecting efficiency."
"The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers."
"The scalability is good with Amazon, but IBM had some issues."
"Mobile application testing will be an added benefit for us if LambdaTest implements this really soon."
"LambdaTest needs to improve its speed and memory because it takes a long time to load."
"I didn't like the solution's technical support and how they communicated and tried to fix the issues of customers like me."
"LambdaTest needs to have native application testing, which would be a great help to my team."
 

Pricing and Cost Advice

"We have a yearly license for 16 devices."
"It's not cheap, but there are a few different packages and different prices for enterprises with different product versions."
"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."
"I believe the licensing cost is cheap because it's a total solution, hardware, license and software."
"LambdaTest is on the cloud, offers both free and paid plans which start at $19 USD per month."
"This is an affordable product."
"It is 60% cheaper and there is no fuss in maintaining the lab, so we have more time to do the testing."
"The tool is not cheap, but it is not expensive."
"LambdaTest is paid per execution."
"LambdaTest's pricing is cheaper than that of other similar platforms."
"It is free to start, which means you can actually see how it works and then take the decision to buy."
"The pricing could be made cheaper."
