Mid-market and enterprise teams building APIs or JavaScript-heavy web apps need Probely (Snyk API & Web) because it actually discovers what you're running before it scans it, eliminating the guesswork that kills DAST programs. The headless Chrome spider handles modern SPAs and the native API scanning accepts OpenAPI and Postman Collections directly from your existing tooling, cutting weeks off typical deployments. Skip this if your primary concern is SAST or supply chain risk; Probely owns the runtime security layer (NIST ID.RA and PR.PS) but doesn't pretend to be your code scanner.
