Insomnia REST Client vs Soap UI: 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, Soap UI is detailed as "An open source SOAP and REST API testing tool". It is an open source functional Testing tool for API Testing. It supports multiple protocols such as SOAP, REST, HTTP, JMS, AMF and JDBC. It supports functional tests, security tests, and virtualization.
Insomnia REST Client and Soap UI can be primarily classified as "API" tools.

According to the StackShare community, Insomnia REST Client has a broader approval, being mentioned in 35 company stacks & 30 developers stacks; compared to Soap UI, which is listed in 11 company stacks and 4 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.
