Deploy your Convex app to Fly.io
Step-by-step deployment help for Convex apps on Fly.io. We fix Convex-specific deployment issues, configure Fly.io, and get your app live. From $19.
Convex issues we fix before deploying
Common Convex problems that affect Fly.io deployments.
Missing access control on mutations
Convex mutations without identity checks, allowing any client to create, update, or delete data without authentication.
Overly broad queries
Queries that fetch entire tables without filters, sending massive amounts of data over real-time subscriptions and consuming read bandwidth.
No schema validation
Missing schema.ts definitions, allowing any shape of data to be inserted and causing type mismatches at runtime.
Inefficient reactive queries
Queries that re-execute on unrelated data changes because they scan too broadly, causing unnecessary re-renders in the frontend.
Fly.io deployment issues we check for
Common Fly.io problems that break Convex 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 Convex app to Fly.io?
We handle Convex deployments to Fly.io end to end. Start with our code audit ($19) to identify deployment blockers specific to your Convex project, then we configure Fly.io, fix issues, and get your app live in production.
What Convex issues affect Fly.io deployments?
Convex projects commonly have missing access control on mutations and overly broad queries. 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 Convex project to Fly.io?
Yes. We specialize in deploying Convex applications to Fly.io. We audit your codebase for Convex-specific issues, configure Fly.io correctly, and handle the full deployment so your app runs reliably in production.
What does Convex deployment to Fly.io cost?
Our code audit ($19) identifies all Fly.io deployment blockers in your Convex project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
