Built with Fine.dev? Deploy it to Heroku.
Step-by-step deployment help for Fine.dev-built apps on Heroku. We fix deployment issues, configure Heroku correctly, and get your app live in production. From $19.
Fine.dev issues we fix before deploying
Problems specific to Fine.dev's code generation that affect Heroku deployments.
Spec interpretation may differ significantly from intent
Fine.dev builds exactly what the specification says, not what you meant. Ambiguous specs lead to technically correct implementations that miss the actual product requirement.
Cross-file changes may miss security implications
When Fine.dev generates features spanning multiple files, security-sensitive changes — new endpoints, auth checks, data access patterns — are spread across the PR without a consolidated security review surface.
Generated tests may not cover real-world edge cases
Fine.dev writes tests for the happy path and obvious failure cases from the spec. Edge cases not explicitly mentioned — concurrent requests, null inputs, rate limits — are frequently untested.
Cross-file changes introduce inconsistencies
Large implementations touching many files accumulate subtle inconsistencies — type assumptions that don't hold across modules, different error handling patterns in different files.
Heroku deployment issues we check for
Common Heroku problems that break AI-generated 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
Can you deploy a Fine.dev-built app to Heroku?
Yes. We regularly deploy Fine.dev-generated projects to Heroku. We handle the platform-specific configuration, fix deployment errors, and ensure your app runs reliably in production on Heroku.
What Heroku issues do Fine.dev projects typically have?
Fine.dev projects commonly have spec interpretation may differ significantly from intent and cross-file changes may miss security implications. When deploying to Heroku, these combine with platform-specific issues like free dyno sleeping causes cold starts and ephemeral filesystem loses uploaded files.
How do I get my Fine.dev project live on Heroku?
Start with our code audit ($19) to get a prioritized list of deployment blockers. For Fine.dev-built projects targeting Heroku, the typical path is: fix Fine.dev-specific code issues, configure Heroku settings correctly, then deploy. We provide a fixed quote after the audit.
Can you handle the full deployment of my Fine.dev app to Heroku?
Yes. We handle end-to-end deployment: auditing your Fine.dev codebase, fixing deployment blockers, configuring Heroku correctly, setting up environment variables, and getting your app live in production. Start with our code audit ($19).
