Built with Base44? Deploy it to Fly.io.
Step-by-step deployment help for Base44-built apps on Fly.io. We fix deployment issues, configure Fly.io correctly, and get your app live in production. From $19.
Base44 issues we fix before deploying
Problems specific to Base44's code generation that affect Fly.io deployments.
Platform lock-in makes it expensive to migrate to self-hosted infrastructure
Base44 applications run on Base44's infrastructure with proprietary abstractions. If you need to migrate to AWS, Vercel, or a custom backend, you must substantially rewrite the application since the generated code is tightly coupled to Base44's runtime.
Auto-generated backend API lacks input validation and allows malformed data into the database
Base44's generated REST API endpoints often accept and persist any data that matches the field type without business-rule validation — missing required fields, out-of-range values, or invalid relationships are stored without error.
Limited customization of business logic after the initial app generation
Once Base44 generates the application structure, adding custom business logic that deviates from the generated patterns — complex workflows, conditional processing, third-party integrations — requires working around the platform rather than with it.
Database schema changes after initial generation are difficult and risk data loss
Modifying the generated database schema after data has been collected — adding columns, changing relationships, renaming tables — is fragile in Base44 and may require manual data migration that the platform does not assist with.
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 Base44-built app to Fly.io?
Yes. We regularly deploy Base44-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 Base44 projects typically have?
Base44 projects commonly have platform lock-in makes it expensive to migrate to self-hosted infrastructure and auto-generated backend api lacks input validation and allows malformed data into the database. 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 Base44 project live on Fly.io?
Start with our code audit ($19) to get a prioritized list of deployment blockers. For Base44-built projects targeting Fly.io, the typical path is: fix Base44-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 Base44 app to Fly.io?
Yes. We handle end-to-end deployment: auditing your Base44 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).
