Performance for your FastAPI project
Expert performance for FastAPI applications. We find and fix FastAPI-specific performance issues that affect production apps. From $19.
FastAPI performance issues we find
Common performance problems specific to FastAPI applications.
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.
What our FastAPI performance covers
Page load speed
Bundle size optimization, code splitting, image optimization, and reducing time to first meaningful paint.
Runtime performance
Eliminating unnecessary re-renders, optimizing state management, and fixing memory leaks.
Database optimization
Query optimization, adding indexes, implementing pagination, and eliminating N+1 queries.
API response times
Caching strategies, response compression, connection pooling, and reducing round trips.
Core Web Vitals
LCP, FID, and CLS optimization for better user experience and search rankings.
Caching strategy
Browser caching, CDN configuration, server-side caching, and cache invalidation.
