Score: 6.5/10 (Innovation: 6, Technical: 6, Documentation: 8, Utility: 6)

This project implements a 'spec compiler' that transforms a PRD markdown file into a bootable FastAPI application with CRUD, auth, migrations, and tests, using deterministic model-to-text generation without LLM calls. Its innovative approach combines formal spec-driven development (with ArchiMate typing) with practical web app scaffolding, offering a reproducible alternative to agent-based code generation.

Target audience: backend devs
