Reviews for Postman
Hear what real users highlight about this tool.
Reviews praise Postman’s reliability for testing, collaboration, and documentation, with many noting quick onboarding and strong collection/workspace workflows. Makers of LOQUIS, Krepling, and ezyClients highlight smooth API testing at scale, citing concurrent endpoint tests, transaction-volume simulation, and easy sharing. Users value the collection runner, scripts, and request-to-code generation. Common drawbacks: high memory usage, occasional slowness/bloat, confusing UI in places, and minor hiccups like tab management and lost GraphQL history. Best suited for exploratory testing and team collaboration; some automate elsewhere.
This AI-generated snapshot distills top reviewer sentiments.
Postman was critical in helping our engineering team run concurrent testing across multiple API endpoints under simulated transaction volumes. Its collection-level scripts and pre-request chaining helped us replicate real-world payment behaviors with near-perfect accuracy.
Essential for testing and documenting our API. Postman made it easy to debug requests, share collections, and stay consistent across frontend/backend work.
Helped us quickly test and refine our API responses.
Still my go-to for API testing when I’m debugging backend calls. The clean interface and collection sharing make team workflows smooth. It’s reliable and familiar, but I’m building KraiNode to bring that same ease to blockchain RPCs.
We use Postman to test, automate, and document APIs, ensuring quality before every release.
I used Postman to test, debug, and document my APIs throughout development. It helped me quickly catch issues, organize requests, and share endpoints efficiently. I honestly can’t imagine working on APIs without it.
As a solo dev, Postman helped me stay in control of all API interactions — from initial testing to troubleshooting edge cases.
I've used Postman in multiple projects to sanity-check endpoints before they go into automated flows. The collection runner’s been great for quick regression passes, and I like using it to explore edge cases before they get scripted.
Postman was essential for testing and refining the APIs that power ManaBoard’s backend scraping and job listing processing. It helped ensure reliability while I built solo and iterated quickly.
Testimonial: "Postman made designing and testing our synthetic medical data API incredibly smooth. The collaboration features helped us document endpoints for healthcare developers, and the testing automation caught bugs before our first customers ever saw them. Game-changer for API-first products!"
With its intuitive GUI, built-in testing and collaboration features, Postman streamlines API development far more effectively than plain-text curl scripts
We design and test all of our API endpoints using Postman. But what's really cool is that anyone can trigger a crypto trade from Postman, by calling our API. This helps users execute an immediate trade, programatically. It's also really helpful for testing a Tradingview integration to see if it is working as expected.
Postman is the best tool for exploratory testing of APIs and for collaborating with your team. But for automation, you'll likely outgrow it and want to use a developer based testing framework like RestAssured (Java), SuperTest (JS), or Pytest + Requests (Python)
