Deploy your Convex app to Heroku
Step-by-step deployment help for Convex apps on Heroku. We fix Convex-specific deployment issues, configure Heroku, and get your app live. From $19.
Convex issues we fix before deploying
Common Convex problems that affect Heroku deployments.
Missing access control on mutations
Convex mutations without identity checks, allowing any client to create, update, or delete data without authentication.
Overly broad queries
Queries that fetch entire tables without filters, sending massive amounts of data over real-time subscriptions and consuming read bandwidth.
No schema validation
Missing schema.ts definitions, allowing any shape of data to be inserted and causing type mismatches at runtime.
Inefficient reactive queries
Queries that re-execute on unrelated data changes because they scan too broadly, causing unnecessary re-renders in the frontend.
Heroku deployment issues we check for
Common Heroku problems that break Convex 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 Convex app to Heroku?
We handle Convex deployments to Heroku end to end. Start with our code audit ($19) to identify deployment blockers specific to your Convex project, then we configure Heroku, fix issues, and get your app live in production.
What Convex issues affect Heroku deployments?
Convex projects commonly have missing access control on mutations and overly broad queries. 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 Convex project to Heroku?
Yes. We specialize in deploying Convex applications to Heroku. We audit your codebase for Convex-specific issues, configure Heroku correctly, and handle the full deployment so your app runs reliably in production.
What does Convex deployment to Heroku cost?
Our code audit ($19) identifies all Heroku deployment blockers in your Convex project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
