Deploy your FastAPI app to Supabase
Step-by-step deployment help for FastAPI apps on Supabase. We fix FastAPI-specific deployment issues, configure Supabase, and get your app live. From $19.
FastAPI issues we fix before deploying
Common FastAPI problems that affect Supabase deployments.
Blocking calls inside async endpoints
Synchronous database calls, file operations, or HTTP requests inside async def endpoints block the entire event loop, making your API unresponsive under load.
Missing authentication on endpoints
API routes that handle sensitive data or actions without any auth middleware — Depends() for authentication is simply not included in the route definition.
No CORS configuration
CORSMiddleware either missing (blocking all cross-origin requests) or set to allow_origins=['*'] (allowing any website to call your API).
Pydantic models without validation constraints
Request models that accept any string length, any number range, and any format. No Field() constraints, so invalid data flows through your system.
Supabase deployment issues we check for
Common Supabase problems that break FastAPI apps in production.
Row Level Security disabled on tables
AI tools create tables without enabling RLS, allowing any user with the anon key to read, modify, or delete all data in those tables.
Service role key exposed in client-side code
The service_role key bypasses RLS entirely. AI tools sometimes embed it in frontend code instead of restricting it to server-side operations only.
Edge Functions hitting CPU time limits
Supabase Edge Functions have a 150ms CPU time limit on the free plan. AI-generated functions with heavy computation or unoptimized queries hit this limit under load.
Storage policies too permissive
Supabase Storage buckets created by AI have public access enabled or policies that allow any authenticated user to read all files, ignoring per-user access control.

Frequently asked questions
How do I deploy a FastAPI app to Supabase?
We handle FastAPI deployments to Supabase end to end. Start with our code audit ($19) to identify deployment blockers specific to your FastAPI project, then we configure Supabase, fix issues, and get your app live in production.
What FastAPI issues affect Supabase deployments?
FastAPI projects commonly have blocking calls inside async endpoints and missing authentication on endpoints. On Supabase, these combine with row level security disabled on tables and service role key exposed in client-side code to cause deployment failures.
Can SpringCode deploy my FastAPI project to Supabase?
Yes. We specialize in deploying FastAPI applications to Supabase. We audit your codebase for FastAPI-specific issues, configure Supabase correctly, and handle the full deployment so your app runs reliably in production.
What does FastAPI deployment to Supabase cost?
Our code audit ($19) identifies all Supabase deployment blockers in your FastAPI project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
