Why Postman?

Postman is the leading API platform for organizations, streamlining API development and driving innovation. Unlike traditional, single-player API management tools, Postman fosters team collaboration across the entire API development lifecycle, from creation to deployment.

What about Postman vs. Kong?

Insomnia is a subsidiary of Kong, which offers a range of point solutions for managing APIs and microservices. Kong's products were not developed as part of a single, cohesive strategy; many, like Insomnia, were acquired and later integrated into the ecosystem, resulting in a fragmented user experience. In contrast, Postman was built with a unified vision to serve every stage of the API lifecycle within a single platform.

Postman is trusted by over 500,000 companies, 35 million developers, and 98% of the Fortune 500

One of the first things I do every morning is look at the automated Postman tests that run overnight. We'll know right away if something needs attention. It's a huge time-saver for our team.

Visma company logo
The biggest change has been moving from manual testing to fully automated testing. It's changed our CI/CD pipelines and how we collaborate. All our new features are fully automated and tested with Postman.

We've watched the Postman grow to become a monumental asset. It's made a huge difference. We're able to do audits on what's being tested so we can actually gauge what teams need to be able to better test.

I love that Postman allows us to really organize our APIs. We can add documentation to each API, and add examples of API requests and responses so our developers are never guessing what an API should return.

Senior Software Engineer, WhatsApp Business Platform

One of my favorite things about Postman is the structured way we can run tests. We don't have to duplicate tests for every request; we can just write them once and automate the rest.
