Flask app built with Claude Code? Let’s review it.
Expert code review for Flask apps built with Claude Code. We find Claude Code-specific bugs, fix Flask security issues, and optimize performance. From $19.
Claude Code issues we find in Flask projects
Problems specific to Claude Code's code generation patterns when building Flask apps.
Over-permissive CORS configuration
Claude Code sometimes sets CORS to allow all origins during development and forgets to restrict it for production, allowing any website to make API requests.
Missing rate limiting
API endpoints are generated without rate limiting, allowing attackers to brute-force auth endpoints or abuse expensive operations.
Over-engineered abstractions
Claude Code creates multiple layers of abstraction, generic utilities, and design patterns for simple problems — making the code harder to understand and maintain.
Edge cases in complex logic
While Claude handles the main flow well, complex conditional logic sometimes has edge cases that produce incorrect results with unusual inputs.
Flask issues we check for
Common Flask problems that affect production readiness.
Debug mode in production
Flask's built-in debugger left enabled in production, exposing an interactive console that allows remote code execution on the server.
Hardcoded secret key
SECRET_KEY set to a default or short string like 'secret' instead of a cryptographically random value loaded from environment variables.
No CSRF protection
Forms and state-changing endpoints without Flask-WTF CSRF tokens, enabling cross-site request forgery attacks.
Running with flask run in production
Using Flask's development server in production instead of gunicorn or uWSGI, which is single-threaded and not designed for real traffic.

Frequently asked questions
Can you review Flask code generated by Claude Code?
Yes. We regularly audit Flask projects built with Claude Code and understand the specific patterns and issues it introduces. Our review covers security, performance, and deployment readiness.
What Flask issues does Claude Code typically create?
Common issues in Claude Code-generated Flask code include: over-permissive cors configuration, missing rate limiting, over-engineered abstractions. Combined with Flask-specific concerns like debug mode in production and hardcoded secret key.
How do I make my Claude Code Flask project production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Claude Code-built Flask projects, the typical path is: fix security gaps, address Flask-specific performance issues, then configure deployment. We provide a fixed quote after the audit.
How much does it cost to review Claude Code-generated Flask code?
Our code audit starts at $19 and covers security, performance, architecture, and deployment readiness. For fixes, our Fix & Ship plan is $199. Larger projects get a custom fixed quote — no hourly billing or surprises.
