Deploy your PlanetScale app to Fly.io
Step-by-step deployment help for PlanetScale apps on Fly.io. We fix PlanetScale-specific deployment issues, configure Fly.io, and get your app live. From $19.
PlanetScale issues we fix before deploying
Common PlanetScale problems that affect Fly.io deployments.
Foreign key constraint workarounds
PlanetScale doesn't support traditional foreign keys. AI-generated code creates them anyway, causing deployment failures, or skips referential integrity entirely.
Connection string exposure
PlanetScale database URLs with credentials committed to source control or embedded in client-side code.
Missing connection pooling
Serverless functions opening new connections on every invocation instead of using PlanetScale's connection pooling or @planetscale/database driver.
No branch workflow for schema changes
Schema changes deployed directly to the main branch without using PlanetScale's deploy request workflow, risking production data.
Fly.io deployment issues we check for
Common Fly.io problems that break PlanetScale apps in production.
Dockerfile missing or misconfigured
Fly.io requires a Dockerfile for deployment. AI tools that scaffold without one force flyctl to auto-generate a suboptimal Dockerfile that misses build steps.
Volume only available in a single region
Fly volumes are pinned to one region. Multi-region deployments try to access a volume that doesn't exist in other regions, causing crashes.
Machine restarts losing in-memory state
AI-generated apps store session data or caches in memory. Fly machines can restart or migrate, wiping all in-memory state without warning.
Internal DNS resolution failing between services
Services within a Fly organization communicate via <app>.internal hostnames, but AI-generated code hardcodes localhost or public URLs.

Frequently asked questions
How do I deploy a PlanetScale app to Fly.io?
We handle PlanetScale deployments to Fly.io end to end. Start with our code audit ($19) to identify deployment blockers specific to your PlanetScale project, then we configure Fly.io, fix issues, and get your app live in production.
What PlanetScale issues affect Fly.io deployments?
PlanetScale projects commonly have foreign key constraint workarounds and connection string exposure. On Fly.io, these combine with dockerfile missing or misconfigured and volume only available in a single region to cause deployment failures.
Can SpringCode deploy my PlanetScale project to Fly.io?
Yes. We specialize in deploying PlanetScale applications to Fly.io. We audit your codebase for PlanetScale-specific issues, configure Fly.io correctly, and handle the full deployment so your app runs reliably in production.
What does PlanetScale deployment to Fly.io cost?
Our code audit ($19) identifies all Fly.io deployment blockers in your PlanetScale project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
