Hi HN - author here. FastBackend reads a SQLAlchemy or Prisma schema, compiles it to a framework-agnostic IR, and a runtime adapter serves CRUD + relationships as REST with OpenAPI on the side. Try it in ~2 min: npm i -g @fastbackend/cli git clone https://github.com/darula-hpp/fastbackend cd fastbackend/examples/sqlalchemy-fastapi pip install -r requirements.txt fastbackend generate fastbackend dev open http://localhost:8301/docs What s shipped: - CLI + core on npm (@fastbackend/cli 0.1.2) - FastAPI adapter on PyPI (fastbackend-fastapi) - Express + Prisma adapter on npm - Custom routes and overrides for non-CRUD logic Honest limits: - FastAPI adapter uses in-memory storage (MVP) - Express + Prisma is more production-shaped - No hosted platform — self-hosted codegen/runtime The IR is the interesting part: same schema could be served by different backend adapters. OpenAPI is the frontend handoff (Orval, openapi-typescript, etc.). Roadmap (not shipped): declarative wiring for storage/OAuth with secrets in .env. Happy to answer architecture questions or comparisons to Supabase, PostgREST, FastAPI-CRUD, etc.
