Altair GraphQL Client vs SoapUI

Altair GraphQL Client is an IDE for running and debugging GraphQL queries, mutations and subscriptions. It formats queries, supports file uploads using the multipart specification, and can export query collections. Users can set environment variables for endpoints, headers and queries, then browse schema types and operations in a documentation explorer. Pre-request and post-request scripts and an extensible plugin system add customization options. Altair GraphQL Cloud provides centralized query management, collections, query versioning and shareable query URLs. Official integration packages include Express middleware, Koa middleware, a static build and a Gatsby plugin. The free Basic plan lists up to two team members and 20 queries; Pro costs $7.99 a month per user and lists unlimited team members, teams and queries. The client is available as a web app and on desktop platforms, including Linux, macOS and Windows, with extension and self-hosted options. The maker says the web app is for quick or one-time use, not full development, because it has limitations. Documentation warns that introspection can expose an API schema and that Content Security Policy support is beta.

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.
