Is your Claude Code app production-ready?

Platform-aware security audit for apps built with Claude Code. What it covers, what it typically finds, and how to run one in 30 seconds.

OWASP Top 10 CWE Top 25 CVSS v3 CVE scanning
TL;DR: Claude Code produces high-quality, functional code. The patterns we find most often in Claude Code-built apps: missing rate limiting on API endpoints, no error tracking configured, and dependencies that haven't been audited for known CVEs. Our scanner detects Claude Code's output patterns and runs platform-specific checks on every scan. Free scan: launchreadycode.com.

What a Claude Code security audit covers

A Claude Code security audit covers four dimensions — the same four we check on every app, regardless of how it was built. For Claude Code apps specifically, Security and Monitoring are where the most actionable findings concentrate.

1. Security (highest risk for Claude Code apps)

2. Reliability

3. Performance

4. Monitoring

Claude Code-specific patterns we check

Every AI code tool has characteristic output patterns — the way it structures middleware, handles imports, manages environment variables, and configures error handling. Our scanner is calibrated to Claude Code's patterns, which means faster detection and fewer false positives on the issues that matter.

The three issues we find most often in Claude Code-built apps on first scan: (1) API endpoints without rate limiting middleware — the routes are well-structured but unprotected against abuse; (2) no error tracking configured — the code handles errors internally but nothing surfaces them to the developer in production; (3) dependency versions with known CVEs — packages selected at generation time may have accumulated vulnerabilities.

None of these are flaws in Claude Code. They are standard production hardening steps — rate limiting, observability, and dependency management — that require explicit implementation decisions after code generation.

How to run a Claude Code security audit

Option 1 — Free scan (URL-based, 30 seconds)

Paste your live URL at launchreadycode.com. No code access required. No signup. You get a Launch Readiness Score /100 across all four dimensions plus the top findings. Takes about 30 seconds.

Option 2 — Full audit report ($499 one-time)

The Launch Readiness Audit Report covers every finding with CVSS v3 severity, exact file references where applicable, and specific recommended fixes. Delivered in under 2 minutes. OWASP Top 10 · CWE Top 25 · CVSS v3 methodology.

Option 3 — Self-check (free, manual)

Three things to check before your Claude Code app goes live:

# 1. Check for CVEs in your dependencies
npm audit --audit-level=high
# or
pip-audit  # for Python projects

# 2. Check rate limiting on your auth routes
# Send 20 rapid requests to /api/login or /api/signup
# A 429 response means rate limiting is working
# Repeated 200/401 responses mean it is not

# 3. Verify error tracking is wired up
# Trigger a deliberate error in production
# If you don't receive an alert — monitoring is not configured

Pre-launch security checklist for Claude Code apps

  1. Run npm audit (or equivalent) and resolve all high and critical CVEs before launch. Set up automated dependency scanning (Dependabot or Snyk).
  2. Add rate limiting middleware on every auth route and any AI-backed or payment endpoint.
  3. Configure error tracking (Sentry free tier) and connect it to your deployment environment before go-live.
  4. Set HTTP security headers: Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Strict-Transport-Security.
  5. Add CSRF protection on every state-changing API route.
  6. Audit all environment variables — confirm no secrets appear in client-side code or version control history.

This list addresses the six most common critical and high-severity findings. An LRC scan checks all of these plus 40+ additional vectors across reliability, performance, and monitoring.

Frequently asked questions

Is Claude Code itself unsafe?

No. Claude Code is a capable and well-regarded development tool. The security gaps arise from the inherent scope of code generation — rate limiting decisions, dependency management, observability setup, and security header configuration require production deployment context that goes beyond what any code generator can fully determine. These are standard hardening steps.

How long does it take to fix the issues found?

The six most common issues are all fixable in under 2 hours total: dependency updates (20–30 min), rate limiting middleware (20 min), error tracking setup (10 min), HTTP headers (10 min), CSRF middleware (10 min), environment variable audit (20 min). The scan tells you exactly what to fix. Our Code Care DFY Technical Setup ($1,999 setup fee + $2,999/mo) implements all of it for you.

Do you need code access to run a Claude Code security audit?

No. The LRC scanner is URL-based — it tests what is publicly exposed from your live app, which is where real attackers start. No GitHub access, no source code, no deployment credentials required.

How is this different from a Lovable or Windsurf audit?

The four dimensions and methodology are the same. The platform-specific checks differ — each AI tool produces characteristic patterns in how it structures routes, manages dependencies, and configures error handling. See also: Lovable security audit · Windsurf security audit.
