Microcodegen.py – PRD → FastAPI app, one file, no LLM calls

Microcodegen.py is a developer tool that generates a complete, single-file FastAPI application directly from a Product Requirements Document (PRD), eliminating the need for LLM calls. It is designed for backend developers and API designers who want to rapidly prototype or scaffold production-ready APIs from structured specifications. Its interesting value lies in combining deterministic code generation with a PRD-driven workflow, offering speed and reliability without the cost or unpredictability of AI inference.
