Built with Databutton? Deploy it to Fly.io.
Step-by-step deployment help for Databutton-built apps on Fly.io. We fix deployment issues, configure Fly.io correctly, and get your app live in production. From $19.
Databutton issues we fix before deploying
Problems specific to Databutton's code generation that affect Fly.io deployments.
SQL injection in AI-generated query strings
Databutton's generated FastAPI endpoints sometimes build SQL queries using f-strings or string concatenation with user-supplied parameters, bypassing parameterized query protections entirely.
No authentication on data API endpoints
Data pipeline endpoints are frequently generated without authentication middleware, exposing raw database access and sensitive business metrics to anyone who discovers the API URL.
Unhandled data type mismatches crashing pipelines
Generated data processing code assumes clean input schemas. When upstream data contains nulls, type changes, or unexpected formats, pipelines throw unhandled exceptions and fail silently.
Missing pagination on large dataset queries
Data queries load entire tables into memory without limit or offset clauses. With more than a few thousand rows, responses time out and memory usage spikes.
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 Databutton-built app to Fly.io?
Yes. We regularly deploy Databutton-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 Databutton projects typically have?
Databutton projects commonly have sql injection in ai-generated query strings and no authentication on data api endpoints. 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 Databutton project live on Fly.io?
Start with our code audit ($19) to get a prioritized list of deployment blockers. For Databutton-built projects targeting Fly.io, the typical path is: fix Databutton-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 Databutton app to Fly.io?
Yes. We handle end-to-end deployment: auditing your Databutton 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).
