Building a mvp / prototype with Flask? Let us review it.
Expert code review for mvp / prototype apps built with Flask. We fix Flask-specific security gaps, optimize performance, and handle deployment. From $19.
Common Flask issues we find
Real problems from Flask codebases we've reviewed.
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.
MVP / Prototype challenges to solve
Key mvp / prototype concerns that AI-generated code often misses.
Identifying what actually needs fixing
Not everything needs to be production-grade for an MVP. The challenge is knowing which shortcuts are acceptable (visual polish, advanced features) and which aren't (security, data loss, broken core flows). Our audit prioritizes fixes by impact.
Security minimum
Even an MVP handles user data. You need authentication that works, data isolated per user, no exposed secrets, and HTTPS. You don't need enterprise-grade security, but you need the basics done right.
Deployment
Your app runs locally but deploying it involves environment variables, domain configuration, SSL, and build optimization. First-time deployment is where most AI prototypes hit unexpected issues.
Error handling
When something goes wrong (and it will), your users should see a helpful message — not a white screen or a raw error. Basic error handling is the difference between 'this app is buggy' and 'something went wrong, please try again.'
What we check
Key areas we review for Flask mvp / prototype projects.
Core user flow — does signup to core action work reliably?
Authentication — secure login, session handling, password reset
Data security — user data isolation, no exposed secrets
Deployment readiness — env vars, build configuration, domain setup
Not sure if your app passes? Our code audit ($19) checks all of these and more.

Frequently asked questions
Can you review a mvp / prototype built with Flask?
Yes. We regularly audit Flask mvp / prototype projects and understand the specific patterns and pitfalls of this combination. Our review covers security, performance, and deployment readiness.
What issues do you find in Flask mvp / prototype apps?
Common issues include debug mode in production and hardcoded secret key on the Flask side, combined with mvp / prototype-specific concerns like identifying what actually needs fixing and security minimum. We check for all of these and more.
How do I make my Flask mvp / prototype production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Flask mvp / prototype projects, the typical path is: fix security gaps, address mvp / prototype-specific requirements, optimize Flask performance, then configure deployment. We provide a fixed quote after the audit.
How long does it take to audit a Flask mvp / prototype?
Our code audit delivers a full report within 24 hours. For Flask mvp / prototype projects, we check security, architecture, performance, and deployment readiness across all Flask-specific patterns. Fixes are scoped separately with a fixed quote.
