Portman

Ports OpenAPI specs to Postman Collections with contract/variation tests auto-injected, runnable via Newman.

Desktopfreeglobal

A desktop tool that converts OpenAPI documents into Postman Collections and injects spec-driven contract and variation tests that can be run with Newman, reducing the need to manually write and keep tests in sync as specs change. Intended for API teams and QA engineers working from an existing OpenAPI spec, it supports self-hosted use and is available as an open-source project under the Apache-2.0 license.
