CST VerdictShort answer
Security teams managing REST, SOAP, and GraphQL APIs across multiple domains will get the most from AppCheck API Scanner because it actually discovers endpoints instead of relying on incomplete specs, then tests authorization flaws that static scanners consistently miss. The fixture data generation from Swagger and GraphQL schemas, combined with HMAC and AWS v4 signing support, means you're scanning real API behavior rather than guessing payloads. Skip this if your APIs are behind strict API gateways or if you need post-breach response capabilities; AppCheck is built for vulnerability identification, not incident recovery. Pentesters running high-volume screenshot assessments will appreciate eyeballer for its speed; the CNN model cuts manual review time by flagging UI/UX vulnerabilities that slip past code-focused tools. At 1,240 GitHub stars with zero licensing friction, it's proven enough in the offensive security community to justify a trial. Skip this if your team needs a polished commercial UI or integration with mainstream pentest platforms; eyeballer is a scrappy specialist that works best as a standalone screenshotting aid, not a reporting backbone.
