About Postman

Postman is a widely adopted API development platform that enables developers to build, test, debug, and document APIs from a single interface. It supports REST, GraphQL, gRPC, WebSocket, and other protocols, making it versatile for modern development workflows. Teams use it to collaborate on API collections, run automated tests, and create mock servers without writing extensive boilerplate code. Its intuitive GUI lowers the barrier to entry for API testing, while power features like scripting, environments, and monitors serve advanced users. Postman has become something of an industry standard, with millions of developers relying on it daily.

B
About Insomnia

Insomnia is an open-source API client that helps developers design, debug, and test REST, GraphQL, gRPC, and WebSocket APIs. Originally created as a lightweight alternative to Postman, it offers a clean, intuitive interface that stays out of your way while providing powerful features like environment variables, code generation, and request chaining. It supports OpenAPI spec design and linting through its integration with the Kong ecosystem. Insomnia is well-suited for individual developers and small teams who want a fast, focused API development workflow without excessive complexity.
