Deploy your Flask app to Replit Deployments
Step-by-step deployment help for Flask apps on Replit Deployments. We fix Flask-specific deployment issues, configure Replit Deployments, and get your app live. From $19.
Flask issues we fix before deploying
Common Flask problems that affect Replit Deployments deployments.
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.
Replit Deployments deployment issues we check for
Common Replit Deployments problems that break Flask apps in production.
Development server used in production
AI tools configure Replit to run the dev server (next dev, vite dev) in production instead of building and serving optimized output, wasting resources and exposing debug features.
Secrets exposed in .replit or replit.nix
API keys and database credentials end up in version-controlled configuration files instead of Replit's Secrets manager, visible to anyone who forks the project.
Reserved VM resources insufficient for workload
Replit's reserved VM allocations have fixed CPU and RAM limits. AI-generated apps with heavy processing or multiple services exceed these limits and get throttled.
Outbound networking blocked on free tier
Free Replit deployments restrict outbound network requests, breaking API calls to external services that AI-generated backends depend on.
