I use Postman almost every time I'm working with backend APIs because it lets me test endpoints before connecting them to the frontend. I especially like collections and environment variables since they save me from repeatedly changing base URLs, tokens, and IDs while switching between local and deployed environments. The ability to inspect headers, payloads, status codes, and response times in one place makes debugging much faster. Review collected by and hosted on G2.com.

Once collections start growing, keeping requests organized takes some effort and the desktop app can become noticeably heavier during long sessions. I also wish more collaboration and monitoring features were available on the free plan since many individual developers and students rely on it for learning and personal projects.

I use Postman pretty much every day, and the features I rely on the most are Environments and Variables. Being able to switch between development, staging, and production without editing every single request saves me from making a lot of silly mistakes, especially when I'm juggling multiple projects at the same time. I've also really liked how the API Collaboration features have evolved. Sharing collections, documentation, examples, and test cases with the rest of the team has replaced a bunch of separate documents we used to maintain. Everything lives in one place now, which makes life a lot easier. On top of that, the documentation around Postman itself is some of the best I've worked with. Performance has been solid too. Even with fairly large collections, I rarely run into stability issues. Review collected by and hosted on G2.com.

The only thing I'd point out is that some of the newer features, like Flows and a few of the more advanced collaboration tools, take a bit longer to get comfortable with. Postman has grown into a much bigger platform over the years, so learning the basics is easy, but getting the most out of everything it offers definitely takes some time.

The interface makes it super easy to organize requests, manage APIs, and even automate tests with collections. Plus, the environment variables and scripting with pre-request or test scripts make it super powerful for both manual and automated workflows. Review collected by and hosted on G2.com.

Especially when you have a lot of collections or workspaces open, sometimes the learning curve can be a bit steep if you're diving into things like tests or complex workflows for the first time. So, it’s powerful, but it can be a little heavy at times. Review collected by and hosted on G2.com.

What I like best about Postman is its user-friendly interface and the ability to test APIs quickly without writing additional code. Features like Collections, Environment Variables, and automated testing scripts make API development and debugging much more efficient. It also simplifies collaboration by allowing teams to share API requests, documentation, and test cases in a centralized workspace. Review collected by and hosted on G2.com.

The learning curve can be a bit steep for beginners, especially when working with automated tests, scripting, and complex environment configurations. However, the extensive documentation helps overcome this challenge. Review collected by and hosted on G2.com.

Postman has genuinely transformed the way our team handles API development, and I mean that in the most practical sense — not just as a buzzword.

UI/UX is where Postman first won me over. The interface feels intuitive without being dumbed down. I remember the first time I set up a request chain using pre-request scripts — something that sounds complicated — and it just clicked naturally. The sidebar organization, tabs, and the way collections are structured make navigating even large projects feel manageable.

Integrations have been a pleasant surprise. We plugged Postman into our CI/CD pipeline using Newman (Postman's CLI tool), and now our API tests run automatically on every deployment. It also connects smoothly with GitHub, Slack, and Jira, which means fewer context switches during the day.

Performance is decent for most tasks, though I'll be honest — the desktop app can feel a little slow to load when you have a lot of collections open. Once it's running, though, it's smooth.

Pricing/ROI is where it gets interesting. The free tier is surprisingly generous for individual developers. For teams, the paid plan does add up, but when I think about the hours saved on debugging, documentation, and onboarding — it pays for itself pretty quickly.

Support/Onboarding is solid. Their documentation is some of the best I've seen for a dev tool, and the learning center helped our junior developers get productive fast.

AI features are newer but promising — the AI-assisted test generation has already caught a few edge cases I would have missed writing tests manually. Review collected by and hosted on G2.com.

As much as I enjoy using Postman, there are a few pain points worth mentioning.

The biggest frustration has been the gradual move of features behind the paid plan. Features that used to be free — like certain collaboration tools and increased collection runs — are now restricted unless you upgrade. For solo developers or small teams on a tight budget, that stings a bit. It feels like the product is slowly being nudged toward enterprise customers.

The app performance is another gripe. On older machines or when you have multiple large collections open, Postman can get noticeably sluggish. For a tool I have open all day, startup times and occasional UI freezes are more annoying than they might seem on paper.

I've also noticed that the shift to a cloud-first model hasn't been entirely smooth. Being required to log in to access your own collections felt like a step backward for developers who prefer keeping things local for security or compliance reasons. It caused some friction in our team when it was first introduced.

Lastly, the learning curve for advanced features like writing test scripts, chaining requests, or setting up monitors can be steeper than expected for newer developers. The documentation helps, but some of these features could use better in-app guidance.

None of these are dealbreakers for me personally, but they're real enough that I'd want someone evaluating Postman to know about them going in. Review collected by and hosted on G2.com.

What I like best about Postman is that it provides a complete platform for API development, testing, and collaboration. The user interface is intuitive and easy to navigate, making it simple to create, organize, and test APIs. It integrates well with backend technologies and supports collections, environments, and automated testing, which improves development efficiency. Postman delivers fast performance when sending requests and analyzing responses, helping reduce debugging time. The free version offers significant value for students and developers, making it a cost-effective solution. Its documentation, tutorials, and community resources make onboarding easy even for beginners. I also appreciate the AI-powered features and intelligent suggestions that help streamline API design and testing workflows. Overall, Postman has improved my productivity and made API development more organized, reliable, and efficient. Review collected by and hosted on G2.com.

While Postman is a powerful tool, some advanced features such as extensive collaboration options, monitoring, and API governance are restricted to higher-tier plans, which can be limiting for students and small teams. The interface can occasionally feel overwhelming due to the large number of features available, creating a learning curve for new users. Performance may also slow slightly when working with very large collections or complex automated test suites. Although the onboarding resources are helpful, more guided tutorials for advanced workflows and AI-powered features would improve the experience. Better optimization of workspace synchronization and clearer pricing for premium features would make the platform even more accessible and user-friendly. Review collected by and hosted on G2.com.

Postman is honestly one of the best tools for API testing. Collections make it really easy to organise all your API requests in one place, and environment variables are a lifesaver when switching between dev and production. Mock servers are also very helpful when the backend isn’t ready yet, but you still need to test the frontend. Review collected by and hosted on G2.com.

The app has become noticeably heavier and slower to load than it used to be. It feels like they keep adding more features, and as a result it’s getting increasingly bloated. Automated testing is also a bit complicated to set up for beginners, and the scripting side takes some time to understand. Review collected by and hosted on G2.com.

What I like best about Postman is that we can hit any endpoint, tweak the headers/body/auth, resend and debug in seconds. The requests can be organized into reusable flows which makes onboarding and collaboration much easier.

One more advantage is that we can switch between local/staging/prod environments without rewriting requests using globals which reduces the manual errors of typing the hosts and saves lot of time. Review collected by and hosted on G2.com.

One issue in Postman is that as the collections grow and there are a lot of environments, the app can feel a bity heavy like slow startup. Review collected by and hosted on G2.com.

it is working with APIs very simple and easy to understand . you can quickly test how an API work by sending request and checking the response without writing any code . it also helps you save your work in collection so you can rescue it later . postman is very helpful for teams because everyone can share and test APIs together in one place. overall, it saves time and make API testing faster and more organized Review collected by and hosted on G2.com.

it can sometimes run slowly , especially when we have many request and last collection . some useful features are only available in the paid version , which makes it hard for free user to use everything . it also for beginners , it can feel a little confusing at first because there are many buttons and option . overall, postman is good tool , but it could be made faster and easier to use for everyone Review collected by and hosted on G2.com.

What I like best about Postman is how simple it makes API testing and development. The interface is easy to use, even when working with complex requests, authentication methods, or collections. I regularly use it to test APIs, validate responses, and organize requests in a structured way during development and troubleshooting.

I also find the collection sharing and environment management features very useful because they make collaboration easier across teams. Features like automated testing and request history help save time and improve workflow efficiency during API development. Review collected by and hosted on G2.com.

One thing I dislike about Postman is that the application can sometimes feel resource-heavy, especially when working with large collections or multiple environments at the same time. Performance may slow down occasionally on lower-spec systems during extended usage.

I also feel that some advanced collaboration and workspace features can become a bit complex for new users who are mainly looking for simple API testing. While the platform is powerful overall, there can be a learning curve when exploring advanced automation and team management capabilities. Review collected by and hosted on G2.com.
