Testing for your Claude Code-built FastAPI app
Expert testing for FastAPI apps built with Claude Code. We audit Claude Code-generated FastAPI code for testing issues. From $19.
Claude Code issues we find in FastAPI projects
Problems specific to Claude Code's code generation patterns when building FastAPI apps.
Over-permissive CORS configuration
Claude Code sometimes sets CORS to allow all origins during development and forgets to restrict it for production, allowing any website to make API requests.
Missing rate limiting
API endpoints are generated without rate limiting, allowing attackers to brute-force auth endpoints or abuse expensive operations.
Over-engineered abstractions
Claude Code creates multiple layers of abstraction, generic utilities, and design patterns for simple problems — making the code harder to understand and maintain.
FastAPI testing issues we check for
Testing-specific FastAPI problems that need attention before production.
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.
