Deploy your MySQL app to Heroku
Step-by-step deployment help for MySQL apps on Heroku. We fix MySQL-specific deployment issues, configure Heroku, and get your app live. From $19.
MySQL issues we fix before deploying
Common MySQL problems that affect Heroku deployments.
SQL injection vulnerabilities
String concatenation used to build queries instead of parameterized statements, allowing attackers to read, modify, or delete data.
Missing database indexes
Tables without indexes on columns used in WHERE, JOIN, and ORDER BY clauses, causing full table scans as data grows.
No connection pooling
Opening a new database connection per request instead of using a connection pool, exhausting MySQL's max_connections limit under load.
Credentials in source code
Database host, username, and password hardcoded in application files or committed to version control.
Heroku deployment issues we check for
Common Heroku problems that break MySQL 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 MySQL app to Heroku?
We handle MySQL deployments to Heroku end to end. Start with our code audit ($19) to identify deployment blockers specific to your MySQL project, then we configure Heroku, fix issues, and get your app live in production.
What MySQL issues affect Heroku deployments?
MySQL projects commonly have sql injection vulnerabilities and missing database indexes. 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 MySQL project to Heroku?
Yes. We specialize in deploying MySQL applications to Heroku. We audit your codebase for MySQL-specific issues, configure Heroku correctly, and handle the full deployment so your app runs reliably in production.
What does MySQL deployment to Heroku cost?
Our code audit ($19) identifies all Heroku deployment blockers in your MySQL project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
