Security gaps and vulnerabilities hide in every app. Scan yours in minutes.

Vibio runs 50+ checks, validates them with AI, then sweeps for bugs. Trusted by experienced developers, solo builders & vibe coders for production-readiness audits.

Not just for vibe coders

Whether you shipped fast with AI or spent months hand-crafting every module, production gaps hide in every codebase. Vibio gives experienced developers and teams a systematic audit they can trust: deterministic checks backed by evidence, validated by AI, with nothing left to guesswork.

Think of it as a production-readiness checklist that actually reads your code.

Vibe coders & solo builders

Built fast with Cursor, Copilot, or v0? Vibio catches the gaps AI assistants leave behind: missing auth on routes, no validation, weak CI, hardcoded secrets.

Teams & experienced developers

Use Vibio as a pre-launch audit or an ongoing production health check. 50+ checks across auth, security, CI, observability, and more. With AI review that finds what manual code reviews miss.

How it works

Scan your real codebase. Ship fixes in focused packs.

Step 1

Choose URL or repo scan

Start with a URL scan or connect your GitHub repo. Vibio maps findings and fix packs directly to your production app.

Step 2

Deterministic checks + AI deep review

50+ rule-based checks find concrete issues with file-level evidence. Then AI validates every finding and sweeps for deeper problems the rules can’t catch: auth patterns, error handling, and more.

Step 3

Apply fix packs

Get ordered, scoped Fix Packs with Cursor prompts and PRs. Each pack addresses a cluster of related findings with step-by-step guidance.

What Vibio catches

50+ deterministic checks + AI-powered deep review across your URL surface and codebase, each backed by evidence. Deterministic checks come first because AI-only reviews can miss critical issues or raise false alarms.

Deterministic checks

Rule-based analysis that scans your codebase for concrete, provable issues. Every finding includes the exact file path, line number, and code snippet. This is your security foundation, not a best-guess model output.

AI-powered deep review

AI validates every deterministic finding (agree/disagree, severity adjustments), then runs a full sweep for deeper issues: auth logic flaws, error handling gaps, cookie misconfigurations, and structural problems the rules can't catch. It is a second layer, not the source of truth.

Auth & Sessions

Auth library coverage, unprotected mutation routes, session handling patterns.

Guards & Validation

Zod/Yup/Joi coverage on mutations, input validation boundaries per route.

Security

Secret leakage, env validation, CORS, XSS, SQL injection, security headers.

Payments & Webhooks

Stripe webhook signature verification, idempotency patterns, handler presence.

CI/CD

GitHub Actions presence, build/lint/typecheck/test steps, frozen-lockfile installs.

Type Safety

tsconfig strictness, explicit "any" hotspots in security-critical files.

Tests

Test framework presence, test directories, test execution in CI pipelines.

Observability

Structured logging, request ID middleware, error monitoring (Sentry etc).

Database

Migrations, seed scripts, unscoped query patterns

Dependencies

Lockfile presence, single package manager enforcement, deterministic CI installs.

Works with Next.js, NestJS, Express, Fastify · TypeScript & JavaScript · Supabase, Prisma, Stripe, and more

Frequently asked questions

Everything you need to know about Vibio.

No. You can run a URL scan with zero repo access, or connect your GitHub repo for full codebase analysis. URL scans check headers, exposed keys, rate limiting, and auth surfaces. Repo scans run 50+ deterministic checks + AI-powered deep review with file-level evidence. GitHub permissions are read-only.
We extract your code into a temporary workspace only for the duration of the scan. Once the analysis is complete and findings are generated, the workspace is deleted. We store the scan results (findings, fix packs, artifacts) but not your source code. GitHub connections use read-only permissions.
The URL scan performs external checks on your public-facing app: security headers (CSP, HSTS, X-Frame-Options), exposed API keys or secrets in responses, rate limiting behavior, CORS configuration, and basic auth surface analysis. It gives fast coverage of internet-facing risk and works on its own or alongside a repo scan.
No. Vibio is completely read-only. For URL scans, we only make standard HTTP requests to your public endpoints. For GitHub scans, we download a snapshot of your code, analyze it, and discard it. We never modify files, push commits, or make changes to your infrastructure.
Yes. Vibio has framework-aware detection for Next.js (App Router and Pages Router), NestJS, Express, and Fastify. It understands Supabase auth patterns, Prisma/Drizzle database layers, and Stripe webhook verification. The scanner tailors its checks and fix pack recommendations to your specific stack.
Vibe-coded apps built with AI assistants often have structural gaps: missing auth middleware on API routes, no input validation on mutations, weak tsconfig settings, no CI pipeline, and hardcoded secrets. Vibio scans for all of these and produces ordered Fix Packs so you can close the gaps incrementally without rewriting your app.
Common mistakes include missing RLS policies on tables (allowing public read/write), overly permissive policies, not validating JWTs on API routes, exposing service role keys in client-side code, and not scoping database queries to the authenticated user. Vibio checks for these patterns and flags them with file-level evidence.
Not safely. AI can miss critical vulnerabilities and can also raise false positives. Vibio uses deterministic checks with file-level evidence as the foundation, then adds AI deep review as a second layer to validate findings and catch edge cases.
Claude Code is excellent for building and refactoring code, but it is not a deterministic security scanner. Vibio runs repeatable, rule-based checks with file-level evidence, then layers AI review on top for deeper logic issues and edge cases.
