In their own words
SoapUI
SoapUI is an open-source tool for testing REST, SOAP, and GraphQL web services. It supports drag-and-drop creation of functional and regression tests, assertions, and data-driven tests, and can create service mocks from WSDL. The listed protocols also include JMS and SOAP/WSDL. Functional tests can be extended into load testing, including runs from command-line tools. Named automation integrations include Maven, Hudson, Bamboo, JUnit, and Ant, and SoapUI can run from other CI tools. It can configure incoming and outgoing WS-Security, including encryption, signatures, SAML, keystores, and truststores. SoapUI is described as cross-platform for Windows, Mac, and Linux/Unix. The open-source edition is listed for basic functional and performance testing; security testing appears among expanded capabilities associated with ReadyAPI. The listed SoapUI Open Source plan is free and includes API testing, mocking, and command-line automation. SmartBear describes it as a starting point for developers and testers, with support and a community forum linked on the site.
Yaak
Yaak is a local-first desktop API client for sending requests, debugging APIs, and collaborating through Git. It runs on Linux, macOS, and Windows, and supports HTTP/REST, GraphQL, gRPC, WebSocket, and server-sent events. Users can arrange requests in workspaces and folders, switch environments, and reuse authentication and variables. Directory sync stores requests, folders, and environments as individual YAML files for Git workflows.
Yaak imports work from Postman, Insomnia, Bruno, OpenAPI, and curl. Plugins support authentication, importers, and template functions, with a 1Password plugin for retrieving passwords. The desktop app stores data locally and sends API requests directly to chosen servers; it has no built-in analytics or tracking. Optional workspace secret encryption uses XChaCha20-Poly1305, with the master key protected by the operating system keychain. Free use is for personal purposes; commercial use requires a license. Individual Annual costs $79 a year, and a 30-day trial is available.
