Managing Technical Consultant at a tech vendor with 10,001+ employees
Cross-platform testing has accelerated releases and now needs smarter AI-driven test creation
The best features that BrowserStack offers include the ability to run manual and automated tests on real devices. We can create bugs, integrate it with other platforms like Jira or Azure, and use self-healing scripts with Selenium. We also have the test runs for different versions or with different frameworks, not just Selenium but with Playwright as well. Additionally, there are real-time dashboards and notifications sent when tests fail or when we need screenshots or recordings of test executions, and we can easily integrate this into our pipelines. BrowserStack has positively impacted my organization by providing an out-of-the-box solution for whole test executions across different projects for our automobile customers. We have worked on around twenty to thirty projects, and the need for a stable, customizable single test execution platform that supports different platforms has been met. It has helped manage the entire quality assurance of the product efficiently. The measurable improvements due to BrowserStack include a significant efficiency gain, allowing the whole team to collaborate on testing and communicate faster. Also, the easier integration with project management tools has been beneficial. The documentation of findings has improved, which helps us share insights with different project stakeholders.

One area where k6 could improve is by introducing a GUI similar to JMeter. While k6 is a powerful tool for performance testing, it leans heavily towards coding. Having a GUI, even if it is a low-code approach, could make it more accessible to a broader audience. It would be beneficial to strike a balance where basic tasks can be performed graphically through a user-friendly interface, while still allowing the flexibility for more complex operations through code, similar to how JMeter operates. This could enhance the user experience and make k6 more approachable for those who may not be as comfortable with scripting.

Quotes from Members

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

Pros

"BrowserStack has lots of devices to choose from."
"BrowserStack has positively impacted my organization primarily through time savings because it is very easy to use and replicates physical devices for testing, which is crucial since we usually do not have physical devices."
"For BrowserStack, it's helpful for me to test on different devices."
"The BrowserStack interface is easy to use and the webinar has a lot of information."
"BrowserStack has positively impacted our organization by improving collaboration and showing quality improvements in releases, with the number of defects leaking into production significantly reduced."
"It allows us to test our development against a huge range of product combinations that we could not realistically maintain in house, and it really adds to our core capabilities."
"BrowserStack has positively impacted my organization by saving money that would be spent on buying new devices."
"The most valuable feature of BrowserStack is the ability to do manual testing."
"The standout feature of k6 is its strong focus on API performance testing."
"The tool's big advantage is that it is more performance-test oriented for experienced testers who know what they are doing. In a normal working setup, performance engineers frequently work with DevOps and development teams. For these teams, k6 Open Source's syntax is much simpler and easier to understand and apply in the working process."
 

Cons

"We are having difficulty with the payment system for the BrowserStack team, as they only accept credit cards and we are encountering some issues."
"I would like application performance improvement to be better as, for me, it looked a bit slow."
"I think false positives are an area where BrowserStack can improve, as I have often seen things working fine on actual devices, but on BrowserStack devices, issues arise due to network slowness or AWS region connectivity problems that cause lag."
"Customer support could be better. We tried to implement and explore this product with the vendor or reseller's help, but we haven't had any good response about the product."
"I would like for there to be more integration with BrowserStack and other platforms."
"Occasionally, there are disruptions in the connection which can interfere with our testing processes, especially when testing on phones."
"It is difficult to use for someone who has little to no experience."
"Sometimes connectivity can be a problem. We will be in the middle of testing and we will lose connectivity sometimes."
"One area where k6 could improve is by introducing a GUI similar to JMeter."
 

Pricing and Cost Advice

"There are different licenses available that can be customized. You can select the features that you want only to use which can be a cost-benefit."
"My company found the product's license to be very compatible with our budget, and we pay 5,000 to 10,000 per year for licenses."
"The price of BrowserStack is high."
"This solution costs less than competing products."
"BrowserStack could have a better price, but good things have a price."
"The price is fine."
"As for pricing, I can't provide a clear evaluation as I'm not directly involved in those discussions."
"Compared to other solutions, BrowserStack is one of the cheapest."
