Postman Review: The Best API Testing Tool for Developers in 2025?

When you’re working with APIs every day, having the right tools makes a huge difference. Postman has been a staple for developers and QA engineers for years — and for good reason. It’s reliable, full of features, and incredibly easy to get started with. But with so many alternatives popping up lately, does Postman still hold up in 2025?

First Impressions

The installation process is smooth. The desktop app runs on Windows, macOS, and Linux. Once launched, the UI feels clean and modern. You don’t need a manual to figure things out — everything is laid out intuitively. You can send your first API request within minutes of opening the app.

Core Features That Actually Matter

Postman lets you test REST, SOAP, and GraphQL APIs. You can save requests, group them into collections, set environment variables, and use scripting with JavaScript to automate pre-request logic and response validation. It also supports OAuth2, Bearer tokens, basic auth, and more.

Collections are probably the most useful feature. You can structure your API requests like a folder tree, and even write automated tests in the same space. Whether you’re building an internal API or consuming a third-party one, collections save you time and keep everything tidy.

Collaboration and Team Workflows

If you’re working in a team, Postman’s collaboration features are a huge bonus. You can share collections, use version control, and comment directly within requests. Workspaces (both personal and team) help separate different projects and stages of development. If you’re using Postman with GitHub or CI/CD pipelines, integration is straightforward.

Pros of Using Postman

• ✅ Extremely user-friendly – even beginners can pick it up in minutes.
• ✅ Rich feature set – testing, automation, monitoring, documentation, and mock servers.
• ✅ Great for both manual and automated testing workflows.
• ✅ Active community and tons of learning resources.
• ✅ Works offline – no forced cloud dependency.

Cons and Limitations

• ❌ The app can get heavy on RAM when working with large collections.
• ❌ Team features like advanced collaboration require a paid plan.
• ❌ Doesn’t feel as “code-driven” as tools like Insomnia or VS Code extensions.

Postman vs Alternatives

There’s no shortage of competition in 2025. Tools like Insomnia, Hoppscotch, and Thunder Client have gained popularity, especially among developers who prefer lightweight or open-source tools.

Insomnia offers a slick UI and native GraphQL support. It’s more focused on speed and performance. Hoppscotch is browser-based and completely open-source — great for those who want minimal setup. Thunder Client is perfect if you spend most of your time in VS Code and want to skip the external app entirely.

Still, none of them match the overall ecosystem of Postman — especially when it comes to integrations, testing capabilities, and documentation generation.

Is Postman Still Worth It in 2025?

If you’re solo and just need a quick tool to test APIs, even the free plan gives you more than enough. If you’re part of a team working on complex APIs, Postman’s collaborative features save hours — and probably headaches too.

With features like mock servers, built-in monitors, scripting, test automation, and API documentation — Postman is more than just a request sender. It’s a full API lifecycle tool.

Final Verdict

Postman in 2025 is still one of the most well-rounded tools out there for API testing. It strikes a great balance between ease of use and power under the hood. Whether you’re testing a simple endpoint or working on an enterprise-level API, Postman has your back.

That said, it’s not for everyone. If you’re a power user who prefers writing scripts and managing APIs purely in code, tools like Insomnia or CLI-based testers might be more your thing. But for the majority of developers — especially those who value speed and collaboration — Postman is still hard to beat.

Worth trying? Definitely. Worth sticking with? For most developers, yes.
