In their own words
Pynt
Pynt tests API security by analyzing API traffic and creating simulated attacks to identify vulnerabilities. It uses application and API context—including structure, sessions, parameters, users, and roles—to shape its tests. Listed coverage includes OWASP Top 10 risks for APIs, web applications, and LLMs, as well as business-logic scenarios and custom attacks. Findings can include vulnerability evidence, suggested fixes, risk scores, and CWE associations. A CLI supports CI/CD automation, and results are provided in JSON. Pynt can analyze testing assets, Burp XML, HAR recordings, and live traffic sources such as eBPF and ALB mirroring. Listed integrations include Postman, Newman, Python, Rest Assured, Burp, Go, Jest, ReadyAPI, Insomnia, GitHub Actions, GitLab, Jenkins, Azure DevOps, Jira, and Kubernetes. The free Starter plan is limited to 10 API endpoints; Business cloud scans are available under a free trial. Local use requires Docker and Python 3.9 or later. Postman integration requires the desktop app rather than the web interface.
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.
