Deploy your SQL app to Heroku
Step-by-step deployment help for SQL apps on Heroku. We fix SQL-specific deployment issues, configure Heroku, and get your app live. From $19.
SQL issues we fix before deploying
Common SQL problems that affect Heroku deployments.
SQL injection from string concatenation
Building queries by concatenating user input directly into SQL strings instead of using parameterized queries, enabling full database compromise.
Missing indexes on queried columns
Queries filter and join on columns without indexes, causing full table scans that slow exponentially as data grows.
SELECT * in production queries
Fetching all columns when only a few are needed, wasting bandwidth, memory, and preventing covering index optimizations.
N+1 query patterns
Executing one query per row in a loop instead of a single JOIN or batch query, multiplying database round trips by the number of records.
Heroku deployment issues we check for
Common Heroku problems that break SQL 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 SQL app to Heroku?
We handle SQL deployments to Heroku end to end. Start with our code audit ($19) to identify deployment blockers specific to your SQL project, then we configure Heroku, fix issues, and get your app live in production.
What SQL issues affect Heroku deployments?
SQL projects commonly have sql injection from string concatenation and missing indexes on queried columns. 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 SQL project to Heroku?
Yes. We specialize in deploying SQL applications to Heroku. We audit your codebase for SQL-specific issues, configure Heroku correctly, and handle the full deployment so your app runs reliably in production.
What does SQL deployment to Heroku cost?
Our code audit ($19) identifies all Heroku deployment blockers in your SQL project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
