The Postman Open Philosophy

Postman was founded on a straightforward premise: we wanted to simplify each step of building an API so developers could create better APIs—faster. From the very beginning, we open-sourced the Postman Runtime, Postman Collection Format, and our SDKs to allow developers the flexibility to work with APIs in any environment or workflow.

Postman has always believed in open dialogue with our community; we continuously make improvements and add new features based on feedback from our community of more than 10 million developers.

We are transparent with our roadmaps, we constantly communicate our issues, and we support all major API specifications.

That's the Postman Open Philosophy.

But it's more than just a philosophy. We put our commitment to openness into practice every day. Below, you'll find details on a selection of these real-world efforts and projects.

How We're Protecting Your Postman API Keys in GitHub

Developers contribute code to open source projects in GitHub every day; unfortunately, during this process sometimes security credentials are shared by accident. So Postman has implemented a new token-scanning service in GitHub that will send you a notification if you accidentally commit a Postman API key to a public repository. This gives you a chance to respond quickly before there’s any unauthorized access your data.
