Provides real-time application monitoring, but the technical support services need improvement
They could improve the platform's customer support services. Many users, including myself, have experienced significant delays in response times and unsatisfactory resolutions when reaching out for assistance. The support team often provides generic recommendations that do not address the specific issues raised, leading to prolonged downtime. Additionally, there needs to be more proactive communication and follow-up on reported problems. Another area for improvement is keeping pace with updates to the latest libraries and technologies. For example, Sauce Labs' proprietary driver and Saucectl need to be updated more frequently to support the latest versions of popular testing frameworks like Playwright. This lag in compatibility means that users may miss out on critical features and improvements available in newer versions, necessitating workarounds or compromises in their testing workflows.

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

"As stated earlier we use Sauce Labs for a combination of automated testing and manual testing. Therefore the most useful features are the ability to run the functional automated tests via a Sauce Labs tunnels which allows access to applications in our internal network. The second most useful feature is the manual side."
"Easy to integrate with the other platform for tracking purposes."
"It provides a comprehensive selection of browsers and platform versions for our test automations and CI/CD pipeline process. It also provides a comprehensive set of virtual mobile devices, which we can configure for our automation and availability. These features are valuable for us when it comes to testing our applications. We have a website and mobile applications that we want to test and diversify to various browsers and mobile devices as well as restore various versions. This helps us to find bugs that users might be facing and correct them."
"They update for the latest browsers and mobile phones and support a lot of combinations. They have 1,000-plus desktop combinations and browser versions, which is really great. We need that at Applause. The all-in-one testing suite aspect of it is really important because most of our clients prefer to go to one place."
"APPIUM for mobile testing has improved our organization by allowing us to test our website on more devices and browsers than we currently possess."
"I have found the live test section with Sauce Labs to be extremely valuable. When you can't quite figure out why a test is failing, you can go to the live test results section within their tool and launch your test (specifying a given OS/browser, or device) manually and step through the test to see the issue more clearly, usually opening up the developer's tool console and watching the network calls and console (within Chrome) to usually find the underlying issue."
"Sauce Labs provides us with more combinations to test, so we can keep adding platforms and devices to our network. That's been a very seamless experience. Let's say there's an iOS or a private device we need. Sauce Labs has helped get all those set up when needed."
"It runs on the cloud, so you don't have physical setups to run all of this."
"The most valuable features are that it's essentially on-demand, and you only focus on getting the code that needs to be executed without having to worry about the OS, hardware, etc."
"The real devices feature is the most valuable feature for us."
"Our test execution time was reduced to 16 mins from five hours when executed in parallel on multiple VMs. This has been extremely helpful!"
"We use the solution for automation testing and monitoring."
"In case something goes wrong at LambdaTest end, the Support team is extremely responsive to analyze any platform-related issues."
"I was really surprised by LambdaTest; it was a very good service and for the price, I think it is a very good solution."
"It is a scalable solution."
"HyperExecute adds significant speed to execution, enhancing the overall testing process."
 

Cons

"The pricing model of Sauce Labs could be more flexible. Sauce Labs has just one price for the type of solution and a set number of devices. Other solutions have a fee for the base solution and an additional cost per device. If you're a smaller organization, you have to consider your needs. Some smaller companies still need to test various devices, so my advice is to start small and scale up as needed. We had initially planned to start big, but that would have been a big waste."
"They could improve the platform's customer support services."
"One of the challenging areas for us is the reporting and the matrix. It should be based on roles, but right now it is only available for the admin role. The admin role can really do a lot of stuff, but our infrastructure team, which holds the admin role, is not ready to hand it over to us on the testing team. If Sauce Labs had permissions associated with roles, where this role could do this activity and that role could do that activity, it would be easier for us."
"Unable to segregate reports for tests that are currently being developed, and might not be returning useful results."
"I would like for there to be more detail in regards to the quality of our code i.e. how many failures occurred, how many passed based on industry standard metrics, etc."
"We encountered minor issues with stability from time to time but Sauce Labs continues to make improvements."
"With the desktop browser, we can inspect any screen with the web developer option, but they should provide something for mobiles so that we can quickly inspect elements on the device. To write the Selenium scripts, we require web locators. We have to capture them from the local and execute the script on Sauce Labs. If Sauce Labs can provide a solution where we can inspect any of the mobile devices online, it will be very helpful for us."
"User account management needs an overhauls, allowing for user groups rather than just a hierarchy structure."
"If possible to simulate the finger pinch, it would make it more realistic."
"Responsive testing UI is a bit cluttered, whereas the LT browser is much better to use."
"The analytics over the automation dashboard can be more intuitive."
"I didn't like the solution's technical support and how they communicated and tried to fix the issues of customers like me."
"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."
"The tool can improve its testing speed. Changing or switching to another mobile phone can be very slow on a real device."
"You cannot perform native-app testing, as they offer simulation for web testing only."
 

Pricing and Cost Advice

"The pricing is reasonable due to the amount of diversity that they provide. However, I feel they might be more flexible to bargain based on their relationship with our organization."
"They could improve on the pricing because it seems pretty expensive. I'm sure it's justified, but it's expensive."
"We did initially go with Sauce Labs because of the pricing and integration."
"Cost-wise, it's decent. If you have to get the base version out of it, it's the best solution to go with. As compared to other cloud service providers, the pricing of Sauce Labs is decent."
"It could be less like pay-per-use with a lower rate."
"Trial the product and see if it suits your needs."
"Compared with other services, Sauce Labs is a bit expensive."
"Go ahead please. Try it at a smaller scale."
"It is free to start, which means you can actually see how it works and then take the decision to buy."
"This is an affordable product."
"The pricing could be made cheaper."
"From the customer side, LambdaTest is cheaper for big company usage and works fine as other similar applications."
"The pricing for LambdaTest is affordable, and one of the reasons we implemented it."
"LambdaTest is paid per execution."
"LambdaTest's pricing is cheaper than that of other similar platforms."
"The tool is not cheap, but it is not expensive."
