Deploy your Flask app to Cloudflare Pages
Step-by-step deployment help for Flask apps on Cloudflare Pages. We fix Flask-specific deployment issues, configure Cloudflare Pages, and get your app live. From $19.
Flask issues we fix before deploying
Common Flask problems that affect Cloudflare Pages 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.
Cloudflare Pages deployment issues we check for
Common Cloudflare Pages problems that break Flask apps in production.
Workers runtime missing Node.js APIs
AI-generated server code uses Node.js built-ins (Buffer, fs, crypto) that don't exist in the Cloudflare Workers runtime, causing build or runtime errors.
Function invocation limits exceeded
Free tier allows 100,000 function invocations per day. AI-generated SPAs that use functions for every API call burn through limits quickly in production.
KV namespace not bound in wrangler.toml
AI tools reference KV storage in code but forget to declare the KV namespace binding in wrangler.toml, causing undefined binding errors at runtime.
Request body size limited to 100MB
Cloudflare Workers have a strict 100MB request body limit. AI-generated file upload handlers don't implement chunked uploads, failing on larger files.
