Deploy your Cloudflare app to Heroku
Step-by-step deployment help for Cloudflare apps on Heroku. We fix Cloudflare-specific deployment issues, configure Heroku, and get your app live. From $19.
Cloudflare issues we fix before deploying
Common Cloudflare problems that affect Heroku deployments.
Node.js API incompatibility
Code using Node.js-specific APIs (fs, Buffer, crypto) that don't exist in the Cloudflare Workers runtime, causing deployment failures.
Missing security headers
No Content-Security-Policy, X-Frame-Options, or HSTS headers configured, even though Cloudflare makes them easy to add via Workers or page rules.
KV storage race conditions
Cloudflare KV is eventually consistent. Code that reads-then-writes without accounting for propagation delays causes data loss and stale reads.
Worker size limits exceeded
Bundled Workers exceeding the 1MB compressed size limit due to large dependencies, preventing deployment.
Heroku deployment issues we check for
Common Heroku problems that break Cloudflare apps in production.
Free dyno sleeping causes cold starts
Eco and Basic dynos sleep after 30 minutes of inactivity. AI-generated apps with webhook receivers or background jobs break when the dyno is asleep.
Ephemeral filesystem loses uploaded files
AI tools save user uploads and generated files to the local filesystem, but Heroku's ephemeral FS wipes all changes on every dyno restart or deploy.
Database connection pool exhaustion
Heroku Postgres plans have strict connection limits (20 on Hobby). AI-generated apps open a new connection per request, exhausting the pool under moderate traffic.
Procfile missing or incorrect
AI-generated projects lack a Procfile, causing Heroku to guess the start command. For non-standard setups, this guess is often wrong.

Frequently asked questions
How do I deploy a Cloudflare app to Heroku?
We handle Cloudflare deployments to Heroku end to end. Start with our code audit ($19) to identify deployment blockers specific to your Cloudflare project, then we configure Heroku, fix issues, and get your app live in production.
What Cloudflare issues affect Heroku deployments?
Cloudflare projects commonly have node.js api incompatibility and missing security headers. On Heroku, these combine with free dyno sleeping causes cold starts and ephemeral filesystem loses uploaded files to cause deployment failures.
Can SpringCode deploy my Cloudflare project to Heroku?
Yes. We specialize in deploying Cloudflare applications to Heroku. We audit your codebase for Cloudflare-specific issues, configure Heroku correctly, and handle the full deployment so your app runs reliably in production.
What does Cloudflare deployment to Heroku cost?
Our code audit ($19) identifies all Heroku deployment blockers in your Cloudflare project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
