Deploy your Flask app to Render
Step-by-step deployment help for Flask apps on Render. We fix Flask-specific deployment issues, configure Render, and get your app live. From $19.
Flask issues we fix before deploying
Common Flask problems that affect Render 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.
Render deployment issues we check for
Common Render problems that break Flask apps in production.
Free tier services spin down after 15 minutes
Render's free web services sleep after inactivity, causing 30-50 second cold starts that break webhook integrations and frustrate users.
Build command not set for monorepo projects
AI-generated monorepos lack a root directory or build filter configuration, causing Render to build from the wrong directory or skip the project entirely.
Persistent disk not attached for file uploads
User-uploaded files disappear on redeploy because AI tools write to the ephemeral filesystem instead of attaching a Render persistent disk.
Environment groups not linked across services
Database URLs and shared secrets are duplicated across services instead of using Render environment groups, leading to configuration drift.

Frequently asked questions
How do I deploy a Flask app to Render?
We handle Flask deployments to Render end to end. Start with our code audit ($19) to identify deployment blockers specific to your Flask project, then we configure Render, fix issues, and get your app live in production.
What Flask issues affect Render deployments?
Flask projects commonly have debug mode in production and hardcoded secret key. On Render, these combine with free tier services spin down after 15 minutes and build command not set for monorepo projects to cause deployment failures.
Can SpringCode deploy my Flask project to Render?
Yes. We specialize in deploying Flask applications to Render. We audit your codebase for Flask-specific issues, configure Render correctly, and handle the full deployment so your app runs reliably in production.
What does Flask deployment to Render cost?
Our code audit ($19) identifies all Render deployment blockers in your Flask project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
