About The collaboration platform for API development. Simplify each step of building an API and streamline collaboration so you can create better APIs—faster. Postman is a collaboration platform for API development. Postman's features simplify each step of building an API and streamline collaboration so you can create better APIs—faster. Quickly and easily send REST, SOAP, and GraphQL requests directly within Postman. Automate manual tests and integrate them into your CI/CD pipeline to ensure that any code changes won't break the API in production. Communicate the expected behavior of an API by simulating endpoints and their responses without having to set up a backend server. Generate and publish beautiful, machine-readable documentation to make your API easier to consume. Stay up-to-date on the health of your API by checking performance and response times at scheduled intervals. Provide a shared context for building and consuming APIs, and collaborate in real-time.	About ReqKey adds API key authentication, usage credits, rate limiting and request analytics to an API you own. Your own middleware makes a single verify call per incoming request: ReqKey validates the caller’s key, deducts a credit from that consumer’s pool, enforces their rate limit, and records the request with status code, latency and location. It never sits in front of your API — no proxy, no gateway, no DNS change — so it adds no hop to your critical path. Validation averages under 5ms. Credits pool per consumer rather than per key, so issuing a customer a second key does not hand them a second quota, and balances stay synced across regions. Also included: shadow limits, controlled overage, reusable plans, low-credit alerts, and per-request logs filterable by endpoint, status, consumer and time range. ReqKey meters and tracks usage — you keep your own billing stack. SDKs for Python, Node.js, Go, Rust, PHP, .NET and Java, with framework adapters for FastAPI, Express, Django, and more.

Pros & Cons from Real Users Pros I have used Postman for more than 5 years now and never have i faced any lags or stutters in my usage, even with low end computers. Earlier it was available as only desktop application but now it is also available as web application making it more accessible and easy to use, i can login from anywhere and test my endpoints. It keeps my collection and environments saved so i wont have to worry about that also. 1. The application's user interface is intuitive and easy to learn for a new user. 2. Collection and environment can be easily imported. 3. It gives detailed information about each API call with a brief response body which can also be converted into different formats like raw, text or JSON. 4. It supports dark mode which is very useful for all of us developers who likes to work late nights. This is our go-to solution for API testing. It is easy to set up endpoints and save them to a shared workspace. Postman is an excellent software for running APIs. Usage for me, it excelled at was running quick requests and then being able to transform the call into multiple formats. For example, by running a cURL request, you can get the NodeJS, Python, Axios code quite easily. You can also store requests in folders, something that always came in handy was Postman storing a history of previous made requests, so if you didn't save or lost a request, you could always go back to it. The user interface and experience of the application is simplified and curated in such a way that all the necessary features gets highlighted on the screen. It has all the required tools to test the APIs extensively and further share or collaborate with other team members on a project. It has all the requests options for testing like, GET, POST, PUT, DELETE etc. The load time of the requests are pretty quick. All in all, a great tool to test APIs on a live server as well as in a mocking environment. Cons If you are using an free account it does not allow collaboration with many people. I can only think of this cons as of now, also, if you have a company or do serious freelance work you would have business account anyways. I have faced a weird problem with Postman, sometimes when I do an API call I modify the request body and does not save it, and if I close the app and reopen it the request body and API endpoint gets replaced with some random endpoint from the collection that I am using. Would like to see a better mock server implementation. There are no real cons to Postman, it does its job exceptionally well with every feature. For testing SOAP APIs, there are still a lot of improvements needed to be done in the application.
