Performance for your Devin-built FastAPI app

Expert performance for FastAPI apps built with Devin. We audit Devin-generated FastAPI code for performance issues. From $19.

Devin issues we find in FastAPI projects

Problems specific to Devin's code generation patterns when building FastAPI apps.

highSecurity

Autonomous security decisions

Devin makes security-related decisions without human review — choosing auth strategies, setting permissions, and configuring access controls that may be inadequate.

highCode Quality

Compounding architectural errors

When Devin makes an early architectural mistake, it builds subsequent features on top of it. By the time you notice, the issue is deeply embedded in the codebase.

mediumBugs

Workarounds instead of fixes

When Devin encounters an error, it sometimes adds workarounds that mask the root cause rather than fixing the underlying issue.

FastAPI performance issues we check for

Performance-specific FastAPI problems that need attention before production.

performance

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.

performance

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.

performance

Database connections not pooled

Creating a new database connection on every request instead of using a connection pool, causing connection exhaustion under load.
