Deploy your FastAPI app to Netlify
Step-by-step deployment help for FastAPI apps on Netlify. We fix FastAPI-specific deployment issues, configure Netlify, and get your app live. From $19.
FastAPI issues we fix before deploying
Common FastAPI problems that affect Netlify 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.
Netlify deployment issues we check for
Common Netlify problems that break FastAPI apps in production.
Netlify Functions timeout at 10 seconds
AI-generated API routes perform heavy database queries or external API calls that exceed Netlify's default 10-second function timeout, returning 502 errors to users.
Build plugin conflicts with framework adapters
AI-scaffolded projects include conflicting netlify.toml settings and framework adapters, causing build failures or incorrect routing behavior.
Redirect rules not matching SPA fallback
Single-page apps need a /* to /index.html rewrite, but AI tools either omit it or place conflicting rules in both _redirects and netlify.toml.
Forms not detected during build
Netlify Forms require a static HTML form with a netlify attribute at build time. Dynamically rendered forms from React or Next.js are invisible to the build parser.

Frequently asked questions
How do I deploy a FastAPI app to Netlify?
We handle FastAPI deployments to Netlify end to end. Start with our code audit ($19) to identify deployment blockers specific to your FastAPI project, then we configure Netlify, fix issues, and get your app live in production.
What FastAPI issues affect Netlify deployments?
FastAPI projects commonly have blocking calls inside async endpoints and missing authentication on endpoints. On Netlify, these combine with netlify functions timeout at 10 seconds and build plugin conflicts with framework adapters to cause deployment failures.
Can SpringCode deploy my FastAPI project to Netlify?
Yes. We specialize in deploying FastAPI applications to Netlify. We audit your codebase for FastAPI-specific issues, configure Netlify correctly, and handle the full deployment so your app runs reliably in production.
What does FastAPI deployment to Netlify cost?
Our code audit ($19) identifies all Netlify deployment blockers in your FastAPI project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
