Deploy your Firebase app to Heroku
Step-by-step deployment help for Firebase apps on Heroku. We fix Firebase-specific deployment issues, configure Heroku, and get your app live. From $19.
Firebase issues we fix before deploying
Common Firebase problems that affect Heroku deployments.
Open security rules
Firestore and Realtime Database rules set to allow all reads and writes, making your entire database public.
Client-side admin SDK usage
Firebase Admin SDK credentials or service account keys exposed in client-side code.
Inefficient Firestore queries
Reading entire collections when only a few documents are needed, or missing composite indexes causing query failures.
No offline data handling
Apps crash or show stale data when connectivity drops because offline persistence isn't configured properly.
Heroku deployment issues we check for
Common Heroku problems that break Firebase 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 Firebase app to Heroku?
We handle Firebase deployments to Heroku end to end. Start with our code audit ($19) to identify deployment blockers specific to your Firebase project, then we configure Heroku, fix issues, and get your app live in production.
What Firebase issues affect Heroku deployments?
Firebase projects commonly have open security rules and client-side admin sdk usage. 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 Firebase project to Heroku?
Yes. We specialize in deploying Firebase applications to Heroku. We audit your codebase for Firebase-specific issues, configure Heroku correctly, and handle the full deployment so your app runs reliably in production.
What does Firebase deployment to Heroku cost?
Our code audit ($19) identifies all Heroku deployment blockers in your Firebase project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
