Snyk API & Web is the better pick if you mainly scan APIs inside a Snyk shop, or want a free DAST plan with a 14-day full trial. AttackerView is the better fit if you want published pricing, attack chains and AI pentests without an Enterprise contract.
Snyk API & Web, formerly Probely, is Snyk's cloud DAST scanner for web apps and APIs. Snyk acquired Probely in 2024 and relaunched it in 2025; it is sold standalone or as part of the Snyk platform.
