FAQ

Will this work with Django or Flask instead of FastAPI?

The auth-JWT, rate-limiting, structured-logging, and observability rules apply across Python web frameworks. The FastAPI-specific rules are FastAPI-only. If you're on Django or Flask, ignore those three; the rest still help.

Does this require SQLModel or can I use raw SQLAlchemy?

The sqlmodel-patterns.mdc rule is SQLModel-specific. Raw SQLAlchemy 2.x users can adapt the typed-query and session-per-request principles directly; the rule is short enough to fork.

Personal vs Commercial?

Personal is one developer, unlimited Personal Projects. Commercial covers an entire legal entity (all paid contributors), permits use inside products you sell, and permits internal forking. See LICENSE.
