In their own words
WuppieFuzz
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.
