Deploy your Supabase app to Fly.io
Step-by-step deployment help for Supabase apps on Fly.io. We fix Supabase-specific deployment issues, configure Fly.io, and get your app live. From $19.
Supabase issues we fix before deploying
Common Supabase problems that affect Fly.io deployments.
Missing Row-Level Security policies
Tables without RLS policies are accessible to anyone with the anon key. This is the #1 security issue in Lovable and Supabase-based apps.
Overly permissive RLS policies
RLS policies that use 'true' as the condition, effectively making the table public while giving a false sense of security.
Service role key in client code
The service_role key (which bypasses RLS) exposed in frontend code, giving attackers full database access.
Missing database indexes
Queries slow down as data grows because commonly queried columns lack indexes.
Fly.io deployment issues we check for
Common Fly.io problems that break Supabase 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 Supabase app to Fly.io?
We handle Supabase deployments to Fly.io end to end. Start with our code audit ($19) to identify deployment blockers specific to your Supabase project, then we configure Fly.io, fix issues, and get your app live in production.
What Supabase issues affect Fly.io deployments?
Supabase projects commonly have missing row-level security policies and overly permissive rls policies. 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 Supabase project to Fly.io?
Yes. We specialize in deploying Supabase applications to Fly.io. We audit your codebase for Supabase-specific issues, configure Fly.io correctly, and handle the full deployment so your app runs reliably in production.
What does Supabase deployment to Fly.io cost?
Our code audit ($19) identifies all Fly.io deployment blockers in your Supabase project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
