It's a scalable open-source enterprise application that's easy to maintain and configure

We use NGINX for API routing. API is an open-source solution. It serves as a reverse proxy, routing users to our services without leaving us exposed. API routing is the most valuable feature. The UI could be more attractive. I have used API Gateway for about three months. I rate NGINX API…

Solution simplifies web service testing with impressive speed and accessibility

It is very easy for me to use and I highly prefer it compared to SoapUI and other products for performing its job. It is more handy and faster. It has impacted us very nicely. Postman is used for free by us. I'm not sure if there might be a paid version for multiple users. It is a very good product used for development. It is easy to install, as well as to learn, particularly for new users, even if they are not developers. I taught my business analyst to use it. I just showed them once, and it was easy for them to understand. For example, I gave them the URL and request format and asked them to test independently. They were able to use it on their own and do their testing as well. It was a good experience, especially for generally smart people, like those we usually hire in our company. It is pretty easy to explain, and learning it is not complex.

Quotes from Members

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

Pros

"API routing is the most valuable feature."

"We do not face any lags."

"It's easy to install, and the performance is good."

"It is simple, easy to use and a good tool."

"In Postman, we have an option to directly import a call, make it a Postman collection, and execute it in a batch. This feature is very useful. It saves a lot of time. The manual effort is also reduced when we can just pick it in a Postman collection and then run and execute it to get the results."

"The solution provides visibility for PDF reports without needing to install plugins."

"We use it for REST API testing. Feature-wise, it is pretty lightweight. It is pretty fast, and we don't have to do a lot of things. We can just simply go and post our endpoint, and it gives different kinds of authorizations. We usually use authentication 2.0, which is the most common industry practice. So, it has the support for authorization through 2.0."

"I like that it is very easy to use. I also like the automation feature."

"Postman uses the DRY framework of JavaScript and that framework is easy and a good way to put assertions on responses."

"One of the biggest advantages of Postman is its user-base approach."

"Postman allows you to incorporate and export the test cases we create. It enables me to share the test cases with my colleagues, so I don't have to copy them into an Excel sheet. Postman lets me export the dataset and share it with my team. They can use my test case for their testing."

Cons

"The product must improve its security features."

"The UI could be more attractive."

"It could be more secure because security is always a problem."

"Initially, the setup is a little bit complex. Whenever a user comes to Postman for the first time, it is just a bit complex since they do not know where to start and what is the structure."

"We'd like to see some better UI in newer versions."

"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."

"I have display issues in my Windows that need to be fixed."

"Should have a more improved easy-to-use interface."

"I would like to see improvements in the maintenance of the scripts and their collections. It is really painful that the user cannot drag and drop. It was also painful to create the standard suite of operations for the product. I am not sure if this is improved in the tool’s latest versions. The maintenance of the complex scenarios prompted us to use the solution only for unit testing. In the future, we may switch to the k6 framework."

"One of the primary challenges with Postman is handling authentication issues, especially relating to tokens and passwords."

"If they could implement auto-validations and assertions from SoapUI, that would be a very good feature."

Pricing and Cost Advice

"We are using the open source version, so there is no cost involved."

"We are using the open-source version."

"I use the tool's free version."

"We use the open-source version. They introduced a new licensing model where your company must subscribe to their services if you're using it for business purposes. However, I think they charge too much if you're only using the basic features. It limits what your organization can do if you're not a paying customer."

"The solution is open-source and free."

"The solution has moderate pricing."

"Postman is a free service."

"It is free."

"I rate the price of Postman a four out of five."

"We are using its free version."

Overview

The NGINX Plus API gateway authenticates API calls, routes requests to appropriate backends, applies rate limits to prevent overloading services and to mitigate volumetric attacks, offloads SSL/TLS traffic, and handles errors and exceptions. NGINX's API gateway takes all API requests from a client, determines which services are needed, and delivers the result in a high‑performance manner.

NGINX Plus API gateway is used to protect APIs with rate‑limiting policies, enforce specific request methods, and provide fine‑grained access control:

Ensures application backends are not overwhelmed by a problematic or malicious API clients through rate limits based on attribute of the request.
NGINX Plus allows only specific request methods for app services. For example, you can accept only the GET method to ensure that access to your inventory service is read‑only (just returns the inventory).
Controls access to specific resources using JSON Web Tokens (JWTs). For example, you can allow write access to a service for API clients with admin credentials, but only read access for clients with standard user credentials.

Postman's Tools Support Every Stage of the API Lifecycle. Through design, testing and full production, Postman is there for faster, easier API development - without the chaos.
