What is the best security scanner for Windsurf apps?
The best security scanner for Windsurf apps tests the deployed site, not just the code. CheckVibe (from $0) leads for Windsurf: 100+ checks including the Windsurf-signature failure modes, plus SEO/AEO scanning no competitor offers. VibeEval, Vibe App Scanner, and Scanbee are strong security-only options.
TL;DR
- Cascade's multi-file autonomy makes "review every diff" unrealistic — external verification of the deployed app is the control that scales with agent speed.
- CheckVibe: free tier (4 scans/mo), $24–59/mo paid; the only option that also scans SEO + AEO visibility.
- VibeEval ($19/mo, $199 lifetime) goes deepest on autonomous agent-based security testing.
- Vibe App Scanner ($9–19 one-time) is the cheapest single pre-launch audit.

Windsurf's Cascade agent writes whole features across many files autonomously — which means more code lands per session than you actually read, in exactly the places security bugs live: auth flows, database access, configs. The diffs are too big to review line-by-line; verifying the deployed result externally is the workable strategy.
How we picked
- Tests the deployed app from the outside (what attackers and crawlers actually see), with Windsurf listed as a supported platform or stack-relevant coverage.
- Catches the platform's signature failure modes, not just generic OWASP items.
- Honest pricing with a usable free option where available.
- Output a vibe coder can act on — fix guidance, ideally AI-editor-ready.
The picks
1.CheckVibe
Free (4 scans/mo) · $24–59/moPaste your deployed Windsurf-built URL and get 100+ security checks plus 68 SEO and 46 AEO checks in about 30 seconds — no repo access, no setup. For Windsurf specifically: scan the deployed app after each Cascade session and paste the generated fix prompts straight back into the agent — the loop matches how Cascade works (task in, multi-file change out). Findings ship as copy-paste AI fix prompts, and monitoring (uptime, vitals, threats) covers you after launch.
Best for: All-in-one security + visibility, from $0
2.VibeEval
Free surface scan · $19/mo · $199 lifetimeAutonomous browser-agent security testing of the live app — including behind auth walls and CAPTCHAs (their claim). Security-only. Lists Windsurf as a supported platform.
Best for: Deep agent-based security testing
3.Vibe App Scanner
$9–19 one-time · $99/mo continuousOne-time security audits of the deployed app: exposed secrets, database access rules (Supabase/Firebase), headers, auth. No free scan tier listed as of June 2026. Lists Windsurf as a supported platform.

Do I really need a security scanner for a Windsurf app?
If the app has users, data, or payments — yes. AI-generated apps ship with a consistent set of gaps (exposed keys, missing access control, no headers), and every tool on this list catches issues a manual click-through never will. Start with a free scan; the result settles the question.
Are free security scans enough?
A free scan is enough to find out where you stand today. Paid tiers buy continuity (scheduled scans, monitoring, alerts) and depth (more pages crawled, more checks). For a side project, free-tier scans before each launch may genuinely suffice.
Is code from Windsurf less secure than hand-written code?
Not inherently — but it ships faster than it gets reviewed, and agent-written auth/database code carries the classic AI-codegen patterns (interpolated SQL, missing CSRF, permissive CORS) unless prompted otherwise. The risk is review bandwidth, not the tool.
How do I fix what a scan finds in a Windsurf app?
Feed the findings back to Cascade as tasks. CheckVibe formats each finding as a paste-ready fix prompt; one Cascade task per finding ("add security headers middleware", "parameterize this query") closes them quickly.
