OpenReq vs SoapUI

OpenReq is a free, community-driven API testing application released under the MIT License. It runs as a self-hosted web application, a standalone desktop application, and a Windows client. HTTP, WebSocket, and GraphQL requests are supported as first-class request types, with visual test flows, collection runs, assertions, scripts, delays, conditions, loops, and reports. Automated test runs and API documentation are included, and API testing has no stated usage limits. Collections can become read-only public documentation links, optionally protected by passwords; viewers do not need accounts. OpenReq generates request code for cURL, Python, JavaScript, Go, Java, C#, and PHP. Integrations include Ollama, Postman, OpenAPI, raw cURL, Chrome, and Electron. Ollama can provide local AI features without a cloud API key or sending data away from the machine. The Windows desktop client is frontend-only and needs a separately hosted backend. Most endpoints use JWT bearer authentication, while local proxy setup uses HMAC-signed tokens.

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.
