OpenAPI Specification vs Postman: What are the differences?

Developers describe OpenAPI Specification as "An API description format for REST APIs". It defines a standard, language-agnostic interface to RESTful APIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection. On the other hand, Postman is detailed as "Only complete API development environment". Postman is the only complete API development environment, used by nearly five million developers and more than 100,000 companies worldwide.

OpenAPI Specification and Postman can be primarily classified as "API" tools.

Typeform, Bukalapak, and PedidosYa are some of the popular companies that use Postman, whereas OpenAPI Specification is used by Medidata Solutions, Kapten, and Unmetric. Postman has a broader approval, being mentioned in 1755 company stacks & 2238 developers stacks; compared to OpenAPI Specification, which is listed in 22 company stacks and 8 developer stacks.

From a StackShare Community member: "I just started working for a start-up and we are in desperate need of better documentation for our API. Currently our API docs is in a README.md file. We are evaluating Postman and Swagger UI. Since there are many options and I was wondering what other StackSharers would recommend?"

I use Postman because of the ease of team-management, using workspaces and teams, runner, collections, environment variables, test-scripts (post execution), variable management (pre and post execution), folders (inside collections, for better management of APIs), newman, easy-ci-integration (and probably a few more things that I am not able to recall right now).

I use Swagger UI because it's an easy tool for end-consumers to visualize and test our APIs. It focuses on that ! And it's directly embedded and delivered with the APIs. Postman's built-in tools aren't bad, but their main focus isn't the documentation and also, they are hosted outside the project.

I recommend Postman because it's easy to use with history option. Also, it has very great features like runner, collections, test scripts runners, defining environment variables and simple exporting and importing data.

Postman supports automation and organization in a way that Insomnia just doesn't. Admittedly, Insomnia makes it slightly easy to query the data that you get back (in a very MongoDB-esque query language) but Postman sets you up to develop the code that you would use in development/testing right in the editor.
