Hurl writes requests and response assertions in plain text files with request chaining, is open source under Apache-2.0, and needs no Node.js, though it lacks OpenAPI imports.
httpYac
A command-line and VS Code client for sending HTTP, GraphQL, SOAP and gRPC requests from files.
httpYac runs plain-text request files as CI/CD tests across REST, SOAP, GraphQL and gRPC, with built-in authentication, and also offers a VS Code extension.
Newman

Newman runs Postman collections from the terminal in CI pipelines with Docker images, but depends on collections built in Postman instead of YAML workflows.

Schemathesis generates tests automatically from OpenAPI or GraphQL schemas with property-based fuzzing and ready CI setups, instead of workflows written by hand.
Bruno

Bruno pairs a desktop client with a command line runner for continuous integration, storing collections as plain files in Git, and is open source under MIT.
Insomnia
An API client for REST, GraphQL and gRPC that can keep everything local or sync through Git instead of a cloud.
