Deploy your FastAPI app to GitHub Pages
Step-by-step deployment help for FastAPI apps on GitHub Pages. We fix FastAPI-specific deployment issues, configure GitHub Pages, and get your app live. From $19.
FastAPI issues we fix before deploying
Common FastAPI problems that affect GitHub Pages 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.
GitHub Pages deployment issues we check for
Common GitHub Pages problems that break FastAPI apps in production.
Client-side routing returns 404 on refresh
React Router and other SPA routers break on page refresh because GitHub Pages doesn't support URL rewrites. Only the root index.html is served for the base path.
API routes have no server to run on
AI-generated Next.js or Express backends can't run on GitHub Pages. There's no server-side execution — only static HTML, CSS, and JavaScript are served.
Base path not configured for project sites
Project sites deploy to username.github.io/repo-name, but AI tools build with root (/) as the base path, breaking all asset and route references.
Custom domain DNS propagation issues
CNAME file missing from the build output or DNS records misconfigured, causing the custom domain to point nowhere or show GitHub's 404 page.

Frequently asked questions
How do I deploy a FastAPI app to GitHub Pages?
We handle FastAPI deployments to GitHub Pages end to end. Start with our code audit ($19) to identify deployment blockers specific to your FastAPI project, then we configure GitHub Pages, fix issues, and get your app live in production.
What FastAPI issues affect GitHub Pages deployments?
FastAPI projects commonly have blocking calls inside async endpoints and missing authentication on endpoints. On GitHub Pages, these combine with client-side routing returns 404 on refresh and api routes have no server to run on to cause deployment failures.
Can SpringCode deploy my FastAPI project to GitHub Pages?
Yes. We specialize in deploying FastAPI applications to GitHub Pages. We audit your codebase for FastAPI-specific issues, configure GitHub Pages correctly, and handle the full deployment so your app runs reliably in production.
What does FastAPI deployment to GitHub Pages cost?
Our code audit ($19) identifies all GitHub Pages deployment blockers in your FastAPI project. Full deployment assistance is scoped with a fixed quote after the audit — no hourly billing or surprise charges.
