Parasoft SOAtest vs WuppieFuzz

Parasoft SOAtest automates functional, security and performance testing for APIs and microservices. It can create data-driven, multi-step API tests from recorded traffic or natural-language input without code, and supports more than 120 message formats and protocols, including MCP-based systems. Teams can reuse functional cases for penetration testing or convert them into scriptless, protocol-based performance tests that scale across machines and connect to CI/CD pipelines. Change Advisor identifies API changes and supports bulk refactoring of affected cases; Test Impact Analysis links tests to code changes so teams can run a smaller set. Named integrations include Jenkins, Azure DevOps, Bamboo and TeamCity, with an extension framework for other workflows. The product runs on Windows, Linux and macOS, with desktop, automation-server and web-server deployment options. Appium supports mobile testing on iOS and Android. Reports are available in HTML, PDF, XML and customizable formats, with centralized reporting and analytics available through Parasoft DTP. Pricing is on request. The product page offers a 14-day trial guided by a Parasoft Solution Engineer.

WuppieFuzz is a free, open-source, self-hosted REST API fuzzer built on LibAFL. It generates and mutates requests from an OpenAPI specification to seek potential errors and security flaws. Black-box, grey-box, and white-box testing are supported, along with authentication and input-validation testing. Authentication formats include Bearer, custom, cookie, OAuth, and Web Fuzzing Commons. Code coverage is supported for Java, JavaScript, and Python, while code coverage reports currently support JaCoCo. The tool can produce endpoint coverage reports, and a Grafana dashboard can visualize request information from a fuzzing campaign. It runs on Windows, macOS, and Linux and uses the Apache 2.0 license. TNO says fuzzing data is not shared with TNO or third parties. The tool is described for software development, supply-chain quality control, or penetration testing. WuppieFuzz requires an OpenAPI document in JSON or YAML to generate requests, and API discovery is not supported. Its plan costs nothing.
