Enables users to create scripts easily and provides excellent real-time monitoring features
It is easy to create scripts. We don't have to write any script. Ready-made options are available. We can select, drag, and drop the options, and the script is ready. The solution’s real-time monitoring features have had a huge impact on our service delivery. If we have an application and the script for it, we keep monitoring it. When the script goes red, it indicates that something is not working. So, we check and analyze the applications. We keep track of applications and monitor whether they are live or not. The tool is also useful for monitoring cloud services.

Offers good scalability and has the ability to integrate with various systems and services
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

"As always, within the IT industry, everybody's always looking to upgrade and update everything else like that. Apica has been one of those things but it's really hard to replace because it offers us the unique capability to see what the customer is seeing. A lot of other ones can do Selenium script and things like that, but there's a lot in Apica that we use right now. We utilize a lot of the scenario options in Apica right now, and there's a lot of other ones that do parts of it, but it doesn't do everything that Apica does."
"We see the benefit almost every day. It allows us to be alerted whenever there is a store that is not responding properly around the world. We do have a network operation center (NOC) who receives these alerts, immediately checking if everything is okay."
"It is easy to set up and configure."
"The GUI is powerful and doesn't require scripting or regular expressions. It has a vast finder for correlation, which is easier than other tools like JMeter and LoadRunner. It's also easy to integrate with other tools with a separate execution environment. The tool is also easy to use."
"Anyone can understand the solution easily because it doesn't require a specific scripted language."
"APICa allows me to record APIs easily and enhances scripts through options like auto-correlation, enabling me to access dynamic fields."
"The solution captures all our requests and responses."
"One of the biggest advantages of moving to Apica is the ability get to a hybrid model with the architecture in the cloud and our agents on-prem. We also have access to Apica's cloud agent across the globe. That has changed the way that we have our load testing setup at this point. Previously, it was always internal. Now, with this change in the way it is implemented for load testing, we can test anywhere across the globe and from the list of agents available within Apica's cloud. If I don't have an agent available in a second location, it just takes an email to their customer support, then it is spun up within 24 hours. That flexibility has changed the way that we perceive our load tests, not just in the US, but globally."
"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."
"The standout feature of k6 is its strong focus on API performance testing."
 

Cons

"I have noticed that the tool isn't widely recognized outside our organization. Also, there aren't any tutorials or dedicated resources for this tool, making it challenging for newcomers to learn. It would be beneficial if someone experienced with it could provide guidance."
"Apica was a relatively new tool when I started using it. Although Apica had good documentation, it still felt less developed or advanced than a tool like LoadRunner."
"Apica cannot perform endurance or scale-up tests independently."
"Apica should add more features and integrations with different tools and certain ticketing systems, like ServiceNow."
"Learning the tool has always been a little difficult from a scripting perspective because the framework is proprietary and unique. Once we became used to what it does and how to perform it, then it became easier for my team and me. I would like to see some of the testing steps be part of a more well-known language, like Java or Python. That would be a big improvement."
"It is difficult to create a script using ZebraTester."
"The reporting part that we use for our executives needs a bit more customization capabilities. Right now, you can use only the three main templates for reporting. We would like to be able to customize them."
"Apica is costly, and there's no way to test mobile applications through Apica."
"One area where k6 could improve is by introducing a GUI similar to JMeter."
 

Pricing and Cost Advice

"Apica is pretty cost-effective if you buy both solutions together: Synthetic and LoadTest. If you are going for one solution, the cost is on par with any tool in the market."
"The solution's pricing is not cheap, but it is in the midrange."
"The pricing is very reasonable, but it is not cheap."
"The product is less expensive compared to LoadRunner."
"Another main difference between Apica and the other products was the cost. We really thought that the balance in Apica between the features and costs was the best among all the products on which we did a PoC."
"The tool is completely free and open source. I've been using it for about two and a half years and installed it on both my personal and client machines without needing a license. All features are available for use without any hidden fees."
"License management is another area that Apica could do better. We have already had these conversations with our account teams. This is something that they are looking at largely improving in upcoming releases. I believe that this is already on their roadmap."
"The pricing is fair. It is neither too cheap nor too expensive."
