Pentest-Tools.com API Scanner vs WuppieFuzz

Pentest-Tools.com API Scanner is a cloud service for assessing APIs and detecting vulnerabilities such as SQL injection, SSRF, local file inclusion, code injection, and request URL override. It supports REST and GraphQL APIs, Postman Collections, and OpenAPI 2 and 3 specifications in YAML, YML, or JSON. Authenticated scans can use request headers, including Basic Authorization and JWT tokens. Reports include risk summaries, vulnerability evidence, remediation advice, and a list of more than 40 tests; export options vary by plan and include PDF, HTML, CSV, XLSX, or editable DOCX. Listed integrations include Jira, Slack, Microsoft Teams, Discord, webhooks, Nucleus, Vanta, Burp Suite, AWS, Azure Marketplace, GitHub Actions, and a REST API. A free plan is available. Paid plans start at $95 per month; API scanning is limited in NetSec and included in WebNetSec. The seven-day full-scanner trial requires a business email and card, and costs nothing if canceled before day eight. The company says customer data is encrypted at rest and in transit, and reports are deleted 30 days after generation.

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.
