Flask app built with Cursor? Let’s review it.
Expert code review for Flask apps built with Cursor. We find Cursor-specific bugs, fix Flask security issues, and optimize performance. From $19.
Cursor issues we find in Flask projects
Problems specific to Cursor's code generation patterns when building Flask apps.
Exposed API keys in client code
Cursor often places sensitive keys and secrets directly in client-side components or .env files without the NEXT_PUBLIC prefix distinction, making them accessible in the browser.
Missing input validation on API routes
Server actions and API routes generated by Cursor frequently accept user input without sanitization or schema validation, opening the door to injection attacks.
Unhandled async errors
Cursor wraps code in try/catch inconsistently. Failed API calls, database queries, and file operations often crash the app silently or show raw error messages to users.
Race conditions in state management
Multiple rapid state updates or concurrent API calls cause stale data, UI flickers, and inconsistent behavior — especially in forms and real-time features.
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 Cursor?
Yes. We regularly audit Flask projects built with Cursor and understand the specific patterns and issues it introduces. Our review covers security, performance, and deployment readiness.
What Flask issues does Cursor typically create?
Common issues in Cursor-generated Flask code include: exposed api keys in client code, missing input validation on api routes, unhandled async errors. Combined with Flask-specific concerns like debug mode in production and hardcoded secret key.
How do I make my Cursor Flask project production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Cursor-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 Cursor-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.
