Deploy your Ruby on Rails app to Heroku
Step-by-step deployment help for Ruby on Rails apps on Heroku. We fix Ruby on Rails-specific deployment issues, configure Heroku, and get your app live. From $19.
Ruby on Rails issues we fix before deploying
Common Ruby on Rails problems that affect Heroku deployments.
Mass assignment vulnerabilities
AI-generated Rails controllers that use permit! or don't properly whitelist params, allowing attackers to modify any database column including admin flags and passwords.
Missing authorization checks
Controllers that authenticate users but don't check authorization — a logged-in user can access or modify any other user's data by changing the ID in the URL.
N+1 query problems
ActiveRecord code that loads associated records in loops without includes, eager_load, or preload — causing hundreds of database queries on pages with lists.
Unsafe use of raw SQL
AI tools sometimes generate raw SQL with string interpolation instead of using ActiveRecord's parameterized query methods, enabling SQL injection attacks.
Heroku deployment issues we check for
Common Heroku problems that break Ruby on Rails 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 Ruby on Rails app to Heroku?
We handle Ruby on Rails deployments to Heroku end to end. Start with our code audit ($19) to identify deployment blockers specific to your Ruby on Rails project, then we configure Heroku, fix issues, and get your app live in production.
What Ruby on Rails issues affect Heroku deployments?
Ruby on Rails projects commonly have mass assignment vulnerabilities and missing authorization checks. 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 Ruby on Rails project to Heroku?
Yes. We specialize in deploying Ruby on Rails applications to Heroku. We audit your codebase for Ruby on Rails-specific issues, configure Heroku correctly, and handle the full deployment so your app runs reliably in production.
What does Ruby on Rails deployment to Heroku cost?
Our code audit ($19) identifies all Heroku deployment blockers in your Ruby on Rails project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
