Testing for your Databutton-built FastAPI app

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

Databutton issues we find in FastAPI projects

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

highSecurity

SQL injection in AI-generated query strings

Databutton's generated FastAPI endpoints sometimes build SQL queries using f-strings or string concatenation with user-supplied parameters, bypassing parameterized query protections entirely.

highSecurity

No authentication on data API endpoints

Data pipeline endpoints are frequently generated without authentication middleware, exposing raw database access and sensitive business metrics to anyone who discovers the API URL.

mediumBugs

Unhandled data type mismatches crashing pipelines

Generated data processing code assumes clean input schemas. When upstream data contains nulls, type changes, or unexpected formats, pipelines throw unhandled exceptions and fail silently.

FastAPI testing issues we check for

Testing-specific FastAPI problems that need attention before production.

security

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.

security

No CORS configuration

CORSMiddleware either missing (blocking all cross-origin requests) or set to allow_origins=['*'] (allowing any website to call your API).

bugs

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.
