Performance for your Claude Code-built FastAPI app
Expert performance for FastAPI apps built with Claude Code. We audit Claude Code-generated FastAPI code for performance 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 performance issues we check for
Performance-specific FastAPI problems that need attention before production.
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.
No rate limiting on public endpoints
Public API endpoints (especially AI wrapper endpoints that call OpenAI or similar) have no rate limiting, so a single user can run up massive costs.
Database connections not pooled
Creating a new database connection on every request instead of using a connection pool, causing connection exhaustion under load.
