Deploy your Netlify app to Fly.io

Step-by-step deployment help for Netlify apps on Fly.io. We fix Netlify-specific deployment issues, configure Fly.io, and get your app live. From $19.

Netlify issues we fix before deploying

Common Netlify problems that affect Fly.io deployments.

Deployment

Missing redirect rules for SPAs

Single-page apps without a _redirects file or netlify.toml rewrite rules, causing 404 errors when users navigate directly to routes.

Security

Environment variable misconfiguration

Build-time vs runtime environment variable confusion, or sensitive keys set in the wrong context (deploy previews, branch deploys).

Performance

Serverless function cold starts

Netlify Functions with large dependencies or no connection pooling, causing timeout errors on the first invocation after idle periods.

Deployment

Missing build optimization

No caching configured for node_modules or build artifacts, causing unnecessarily long build times and deployment delays.

Fly.io deployment issues we check for

Common Fly.io problems that break Netlify apps in production.

Config

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.

Networking

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.

Performance

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.

Networking

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 Netlify app to Fly.io?

We handle Netlify deployments to Fly.io end to end. Start with our code audit ($19) to identify deployment blockers specific to your Netlify project, then we configure Fly.io, fix issues, and get your app live in production.

What Netlify issues affect Fly.io deployments?

Netlify projects commonly have missing redirect rules for spas and environment variable misconfiguration. 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 Netlify project to Fly.io?

Yes. We specialize in deploying Netlify applications to Fly.io. We audit your codebase for Netlify-specific issues, configure Fly.io correctly, and handle the full deployment so your app runs reliably in production.

What does Netlify deployment to Fly.io cost?

Our code audit ($19) identifies all Fly.io deployment blockers in your Netlify project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
