AppCheck SPA Scanner vs AppCheck Web App Scanner: Side-by-Side Comparison (2026)

AppCheck SPA Scanner

Teams securing modern frontend applications built on React, Vue, or Angular need AppCheck SPA Scanner because its event-based crawler actually navigates SPAs the way users do, catching authorization flaws and IDORs that traditional DAST misses on client-heavy apps. The tool handles scripted authentication including TOTP and multi-domain scanning across frontend and backend interactions, covering OWASP categories and 100,000+ CVEs without framework lock-in. Skip this if your application portfolio is primarily server-rendered monoliths or you need extensive SIEM integration; AppCheck's integrations lean toward CI/CD tooling like TeamCity and Jira rather than security operations platforms.

AppCheck Web App Scanner

SMB and mid-market teams without dedicated AppSec staff should pick AppCheck Web App Scanner for its automated authentication handling, which removes the manual setup that kills most DAST programs before they start. The scriptable browser interface handles multi-stage login flows and TOTP/MFA natively, so your developers can actually run scheduled scans without constant tuning. Skip this if you need SAST integration or code-level vulnerability tracking; AppCheck is web-facing attack surface only, and its Jira integration won't replace your code scanning pipeline.
