VibeCheck is the first AI Enforcement Security tool — it proves whether AI-written code actually enforces the security it claims.
Traditional scanners find bugs. We audit claims vs reality. That's a fundamentally different job.
100% local verification • No uploads • No SaaS dependency
AI-generated code hallucinates security guarantees.
// Protected by auth middlewareimport { rateLimit } from 'express-rate-limit'// TODO: Add validation before prodconst isAdmin = checkRole('admin')We're creating a new category. It's important to be clear about what that means.
We don't scan for code patterns
We don't check CVE databases
We don't enforce code style
We don't tick boxes
We verify controls actually run
We test comments against code
We prove what's true, not assumed
We show evidence, not assertions
The bridge to understanding
Does the code say it's secure but isn't? Is validation claimed but missing? Is auth assumed but not enforced? This is how developers first understand VibeCheck.
The philosophy
No uploads. No SaaS dependency. No CI lock-in required. Deterministic, local verification. Your source code never leaves your machine.
The emerging frontier
Security isn't just auth — it's cost explosion, prompt injection, and compute misuse. VibeCheck audits AI-era risks that traditional tools ignore.
Purpose-built for modern web apps. Understands Next.js, Express, and common auth patterns.
Unprotected routes, middleware gaps, role enforcement
Client-only validation, ignored Zod schemas
SSRF, CORS, open redirects, missing timeouts
Unpinned deps, postinstall scripts, deprecated packages
Unused imports, comment-only protection, phantom middleware
Unbounded AI calls, missing cost controls, prompt injection
The free version gives you all scanners and proof-based findings. Pro adds visualization, traces, and advanced policy features.
No account, no limits
For solo founders shipping fast
Advanced tools for developers who want more than just findings
Visual dashboard to explore enforcement evidence, filter by claim type, and drill into code
See exactly how data flows through your app — from request to enforcement checkpoint
Simulate waivers and downgrades before committing. See how policy changes affect your posture
Compare scans over time. Catch when enforcements disappear or new gaps appear
AI-powered pattern detection across findings. Spots auth+validation gaps, middleware bypasses
Interactive route maps showing enforcement coverage, middleware layers, and security boundaries
Export findings as PDF reports for compliance, audits, and client deliverables (Pro-only)
Direct email support with faster response times from the team that builds VibeCheck
Your code never leaves your machine. No cloud uploads, no telemetry, no phone-home. This is the ethos of AI Enforcement Security.
All enforcement verification runs locally. Your source code stays on your machine.
Ed25519 signatures verified locally. No internet required after activation.
The only server interaction is generating keys. Nothing else phones home.

Simple, transparent licensing with complete offline verification
Choose monthly or annual billing through Stripe. Secure checkout, instant access.
Access your Pro Portal and generate a 90-day license key. Generate new keys anytime.
Paste your key in the viewer or run `vibecheck activate`. Verification happens offline.
VibeCheck reminds you before expiry. Generate a fresh key from the Portal in seconds.
VibeCheck never contacts our servers during scans. License verification uses cryptographic signatures that work completely offline. The Portal is only used for billing and key generation.
Common questions about AI Enforcement Security
AI Enforcement Security is a new category of tools that prove whether security, privacy, and abuse controls actually exist and are enforced in AI-generated code — not just implied, commented, or assumed. Traditional security tools scan for vulnerabilities. VibeCheck verifies enforcement reality. That's a fundamentally different job.
Vulnerability scanners look for known bugs and CVEs. VibeCheck doesn't find bugs — it audits claims vs reality. When AI writes '// Protected by auth' but the middleware doesn't actually cover that route, that's not a bug in the traditional sense. It's an enforcement gap. We prove what's true, not what's claimed.
AI-generated code often hallucinates security guarantees. It writes comments claiming protection exists, imports security libraries but doesn't use them, or creates middleware that never gets wired up. The code looks secure on inspection but provides no actual protection. VibeCheck detects these patterns.
The free version includes all 30+ enforcement verification scanners, proof-based findings with evidence, and exportable reports (JSON/Markdown/SARIF). You get the full verification engine — Pro adds the interactive viewer, proof traces, regression tracking, PDF exports, and advanced policy features.
Security tools that analyze your source code shouldn't require uploading that code anywhere. VibeCheck runs 100% locally with no cloud dependency. Even license verification uses cryptographic signatures that work offline. This isn't just privacy — it's philosophical: verification should be deterministic and self-contained.
VibeCheck works best with Next.js, Express, and Node.js projects. It understands NextAuth, Clerk, Supabase Auth, and other common auth libraries. Framework-specific scanners detect patterns like unprotected API routes in Next.js App Router or missing middleware in Express.
Yes! VibeCheck outputs SARIF format for GitHub Security tab integration, plus JSON and Markdown for custom workflows. Run `vibecheck scan --format sarif` in your pipeline. The free version works great for CI — Pro adds baseline comparisons and regression detection.
Security isn't just about auth anymore. AI-powered apps face new risks: unbounded API calls that explode costs, missing rate limits on AI endpoints, prompt injection vulnerabilities. VibeCheck is one of the first tools to audit these AI-era risks alongside traditional security controls.
AI Enforcement Security is a new category — and VibeCheck is leading it. Prove what's enforced, not what's claimed.
