Enterprise-level monitoring facilitates global observability and seamless script creation with intuitive tools
SmartBear, as a vendor, is focusing more on API management and testing rather than monitoring. AlertSite could benefit from more future-focused innovation, especially with competencies in generative AI. Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7. Outside of critical platform issues, there's no continuous support available.

Automated testing optimizes API workflow and collaboration
Since I am using the free tier, one improvement would be to increase the number of requests you can send in a short time period. Currently, if I send 200-300 requests in a short period, Postman Enterprise requires a 30-second wait before sending another bundle of requests unless you upgrade to a higher tier. Secondly, Postman Enterprise sometimes takes several minutes to load the whole workspace. With 2,000-3,000 requests in a workspace, it can take a minute or two to load all requests. When creating a new workspace and moving requests between workspaces, depending on internet speed, it can take a longer period to copy those requests or workspace from one place to another.

Quotes from Members

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

Pros

"This solution has numerous advantages. It's extremely simple to configure. Either digital monitors or single-URL monitors are simple to configure and build."
"The alerting capabilities were really helpful."
"The alerting capabilities of AlertSite were really helpful."
"If there are any issues, it triggers an alert within 30 seconds. When it triggers the alert, we go ahead and check it immediately. The alert is triggered on a real-time basis."
"I highly recommend AlertSite to other users."
"The best feature of AlertSite is that it shows you a visual graph and also sends you notifications about errors, so you get immediate notifications about errors which means that your support team can start taking steps and more quickly make sure the site is up and that customer experience isn't interrupted in terms of using your system and your products. AlertSite is a very good tool. It's user-friendly, and you can see everything on the dashboard. Configuring it is also easy."
"I found multiple features in AlertSite that I like. One is data monitoring history, for example, a history of the blackouts and the data. Sometimes, there's a glitch in the application that AlertSite can capture, and the tool notifies you about that glitch. It also identifies issues that could happen in the future. AlertSite is also a fast tool that you can use to monitor on-premise servers, internal applications, and even global applications. The data is available on a single UI in AlertSite, so there's no need to monitor and click on different applications or URLs. I also love that the tool is quite user-friendly, apart from being fast."
"There are custom reports available along with the inbuilt reports."
"It is easy to install, as well as to learn, particularly for new users, even if they are not developers."
"The environment variables are a valuable feature because I can easily switch them and see all the developments in different cycles and stages."
"The developers put the API in a common workspace which is a nice feature. It makes things much easier and faster to start testing."
"It is a scalable solution."
"I like that it is very easy to use. I also like the automation feature."
"I have enjoyed using parameters and setting parameters while powering directly."
"It allowed us to understand the working and performance of the APIs."
"It is a very stable solution."
 

Cons

"AlertSite sometimes triggers false alerts or fake alerts, which needs to be rectified. When we see an alert and go ahead and run certain tests on it, the test always passes. However, on the main screen, it shows up as critical. Therefore, the false alert needs to be fixed."
"What needs improvement in AlertSite is the documentation, particularly the lack of documentation. If there's a specific activity you want to do, you can't even find information on how to do it, so you have to contact the AlertSite support team to assist you, and only then would the issue be resolved. At the moment, it's not easy to find or get full documentation on how to deal with different issues. You always have to go back to AlertSite support and get help. The documentation for AlertSite could be improved and it's what I'd like to see in the next release of the tool because at the moment, the documentation isn't complete, so you'll have to contact support, but contacting support isn't an issue because the team responds to you quickly."
"I could use a few changes to the user interface."
"It is not compatible with all of the product platforms that we use."
"I would like the ability to get more data points with regard to some of the unique requirements that we have."
"One area that needs improvement in AlertSite is the slow UI. I'm using the classic UI because it's quite user-friendly, or in human-readable format, but it's a little slow. It takes time to load all the monitors, so if that could be sped up, that would be helpful. The AlertSite support team also needs improvement in terms of availability. Most of the agents in the team aren't available 24 x 7, so if there's something you need to discuss, you need to tell the support team ahead of time to schedule it. Multiple times, when a case comes up during weekends or whenever my team is doing an update, support needs improvement, availability-wise. I use AlertSite for synthetic monitoring, so whatever is available right now is okay, but if I want to request a new feature on a website, currently, the UI refreshes automatically. I would like to have the option on AlertSite to configure that manually. The UI auto-updates every few minutes, so if I can control that manually, that would be helpful."
"Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7."
"I don't think there is any need for comments on improvements."
"I would like to see more integrations with other platforms."
"The solution can be improved by providing detailed error logs including the line the error took place to make it easier to correct."
"To get this email reporting function, we have to integrate Postman with Newman. If the two are not integrated, we won't be getting all these things in one group."
"If we have a certain build on one machine it won't work with another build even if we are using the same URL. It would give us a connection refuse. So developing environment compatibility would make it better."
"There are some limitations regarding large result sets in Postman. When dealing with several hundred records, accessing all the information can be challenging."
"Postman needs more advanced data-driven testing."
"Postman quality assurance could improve when doing tests."
 

Pricing and Cost Advice

"The cost is high."
"My company pays to use AlertSite, but I'm unsure of the exact costs because it depends on how many monitors you have."
"We purchased the license once and had the option of selecting the number of user licenses."
"I use the tool's free version."
"We do not pay any money for Postman."
"Postman is a free service."
"We are using the free version that is available."
"The solution's price is reasonable."
"This is an open source solution."
"I rate the product's price a nine or ten on a scale of one to ten, where one is cheap, and ten is very expensive. Postman is an expensive tool for Turkey."
"The solution is free for individuals, but for companies that use it across the organization, you have to pay per user."
