Insomnia REST Client vs OpenAPI Specification: What are the differences?
Developers describe Insomnia REST Client as "The most intuitive cross-platform REST API Client 😴". Insomnia is a powerful REST API Client with cookie management, environment variables, code generation, and authentication for Mac, Window, and Linux. On the other hand, OpenAPI Specification is detailed 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.
Insomnia REST Client and OpenAPI Specification can be primarily classified as "API" tools.
Insomnia REST Client is an open source tool with 10.2K GitHub stars and 590 GitHub forks. Here's a link to Insomnia REST Client's open source repository on GitHub.
According to the StackShare community, Insomnia REST Client has a broader approval, being mentioned in 35 company stacks & 30 developers stacks; compared to OpenAPI Specification, which is listed in 22 company stacks and 8 developer stacks.
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.
