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

"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."
"My company went with AlertSite because as a tool, it's fast, easy to maintain, and provides great support."
"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."
"The return on investment of this solution is well witnessed in our organization because of the integration and various capabilities that it offers to interact with the upstream or downstream systems."
"The alerting capabilities of AlertSite were really helpful."
"The alerting capabilities were really helpful."
"This solution has numerous advantages; it's extremely simple to configure, and either digital monitors or single-URL monitors are simple to configure and build."
"This is a fairly good tool and I would recommend it to others."
"Postman helps reduce almost 90% of the manual effort in processes that we feel could take a lot of manual work."
"It's easy to see different versions of responses."
"The best thing about Postman is it was very easy to use, and we could test APIs and get immediate results."
"The solution has helped us make better APIs, and it is able to provide us with error reports if there are problems with the APIs, which has saved our developers time."
"What is most valuable for me is that we can create and share collections between the team members."
"It is stable and does not lag."
"I rate Postman as a ten out of ten."
 

Cons

"What needs improvement in AlertSite is the documentation, particularly the lack of documentation."
"In terms of support, it is all based on the cost of the subscription that our company purchased, but it wasn't great, and it could've been much better."
"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."
"I would like the ability to get more data points with regard to some of the unique requirements that we have."
"I could use a few changes to the user interface."
"AlertSite requires improvements related to security, even at the enterprise level."
"It is not compatible with all of the product platforms that we use."
"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."
"An area that needs some improvement would be to allow multiple windows with different collections to be open at the same time."
"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."
"When you try to code something and put it in the code, it's not useful."
"If there is any way to have a record and playback feature through UI, as we do in Selenium and IDEs such as Eclipse, it would be great."
"There are definitely features that could be improved; for example, if you derive it from Ready API, maybe Postman can be a good contender and replicate some features such as more scripting and control over API calls."
"The reporting could be better. It should give you a detailed PDF report after you run a test."
"If you have knowledge of JavaScript, the initial setup is easy and straightforward. If not, it may take some time to learn about JavaScript before starting the implementation."
"We need better version compatibility."
 

Pricing and Cost Advice

"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."
"The cost is high."
"This tool is open-source and free to download and use."
"I rate the price of Postman a four out of five."
"The solution is free for individuals, but for companies that use it across the organization, you have to pay per user."
"Postman is a free service."
"I use the tool's free version."
"I am using the free option."
"It is free."
"This is an open source solution."
