Built with Firebase Studio? Deploy it to Fly.io.
Step-by-step deployment help for Firebase Studio-built apps on Fly.io. We fix deployment issues, configure Fly.io correctly, and get your app live in production. From $19.
Firebase Studio issues we fix before deploying
Problems specific to Firebase Studio's code generation that affect Fly.io deployments.
Firestore security rules too permissive by default
Firebase Studio frequently generates Firestore rules that allow authenticated users to read and write any document in the database, without scoping access to documents owned by that user.
Client-side security logic that can be bypassed
Access control checks are placed in frontend React components rather than Firestore rules or Cloud Functions, allowing users to bypass restrictions by making direct Firestore SDK calls.
Cloud Function cold start latency degrading UX
Infrequently-called Cloud Functions take 2-5 seconds to cold start, causing noticeable delays on first API calls and making the app feel slow during low-traffic periods.
Unhandled Firestore transaction conflicts
Concurrent writes to the same documents cause transaction conflicts that are not properly caught or retried, resulting in lost updates and silent data inconsistencies.
Fly.io deployment issues we check for
Common Fly.io problems that break AI-generated 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
Can you deploy a Firebase Studio-built app to Fly.io?
Yes. We regularly deploy Firebase Studio-generated projects to Fly.io. We handle the platform-specific configuration, fix deployment errors, and ensure your app runs reliably in production on Fly.io.
What Fly.io issues do Firebase Studio projects typically have?
Firebase Studio projects commonly have firestore security rules too permissive by default and client-side security logic that can be bypassed. When deploying to Fly.io, these combine with platform-specific issues like dockerfile missing or misconfigured and volume only available in a single region.
How do I get my Firebase Studio project live on Fly.io?
Start with our code audit ($19) to get a prioritized list of deployment blockers. For Firebase Studio-built projects targeting Fly.io, the typical path is: fix Firebase Studio-specific code issues, configure Fly.io settings correctly, then deploy. We provide a fixed quote after the audit.
Can you handle the full deployment of my Firebase Studio app to Fly.io?
Yes. We handle end-to-end deployment: auditing your Firebase Studio codebase, fixing deployment blockers, configuring Fly.io correctly, setting up environment variables, and getting your app live in production. Start with our code audit ($19).
