FastAPI app built with Sweep AI? Let’s review it.
Expert code review for FastAPI apps built with Sweep AI. We find Sweep AI-specific bugs, fix FastAPI security issues, and optimize performance. From $19.
Sweep AI issues we find in FastAPI projects
Problems specific to Sweep AI's code generation patterns when building FastAPI apps.
PRs may be too narrow, missing related bug sources
Sweep fixes the specific symptom described in the GitHub issue but often misses related root causes in adjacent code. The bug reappears from a different trigger after the narrow fix.
Security changes in PRs not reviewed for regression
When a GitHub issue involves auth or permissions, Sweep's generated PR modifies security-sensitive code. These changes require careful human review that automated PR creation workflows can bypass.
Generated tests verify implementation, not behavior
Sweep writes tests alongside its code changes, but the tests assert that the specific implementation works rather than that the feature behaves correctly across realistic input scenarios.
Edge cases not covered when issue description is vague
Sweep implements what the issue says literally. Vague issue descriptions lead to implementations that miss important edge cases — null inputs, concurrent requests, or invalid data.
FastAPI issues we check for
Common FastAPI problems that affect production readiness.
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.

Frequently asked questions
Can you review FastAPI code generated by Sweep AI?
Yes. We regularly audit FastAPI projects built with Sweep AI and understand the specific patterns and issues it introduces. Our review covers security, performance, and deployment readiness.
What FastAPI issues does Sweep AI typically create?
Common issues in Sweep AI-generated FastAPI code include: prs may be too narrow, missing related bug sources, security changes in prs not reviewed for regression, generated tests verify implementation, not behavior. Combined with FastAPI-specific concerns like blocking calls inside async endpoints and missing authentication on endpoints.
How do I make my Sweep AI FastAPI project production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Sweep AI-built FastAPI projects, the typical path is: fix security gaps, address FastAPI-specific performance issues, then configure deployment. We provide a fixed quote after the audit.
How much does it cost to review Sweep AI-generated FastAPI code?
Our code audit starts at $19 and covers security, performance, architecture, and deployment readiness. For fixes, our Fix & Ship plan is $199. Larger projects get a custom fixed quote — no hourly billing or surprises.
