Generate FastAPI project README, setup guides, and human-readable API documentation. Codec8 complements your OpenAPI spec with architecture context and developer onboarding docs.
FastAPI auto-generates Swagger UI, but Swagger is not the documentation your users need. They need a README explaining what the API does, a setup guide for local development, and architecture context that no schema can provide.
Tailored documentation features for FastAPI codebases
Documents Pydantic request and response models with field descriptions and validation rules
Generates endpoint reference beyond Swagger — with auth requirements and error responses explained
Produces Docker Compose setup guide from your compose file and .env requirements
Documents FastAPI dependency injection chains so contributors understand your auth and DB layers

Codec8 follows your APIRouter includes and generates a unified endpoint reference, organized by router prefix, even when routes are spread across dozens of files.
