A backend runtime, not a codegen tool. Point FastBackend at a SQLAlchemy or Prisma schema — it serves CRUD routes, relationships, and OpenAPI at runtime. Routes live in memory, not on disk.
$ fastbackend init my-api --schema sqlalchemy
# → Scaffolds schema, config, and custom endpoints
$ fastbackend generate && fastbackend dev
# → Your API is live at http://localhost:8301/docsThe CLI writes `.fastbackend/ir.json` and OpenAPI from your schema. No CRUD route code is written to disk.
FastAPI and Express adapters register CRUD, relationships, and validation at startup from IR.
SQLAlchemy and Prisma parsers produce the same IR. More formats planned.
Replace any runtime CRUD route with custom handlers using the `@override` decorator.
OpenAPI output works with Orval, openapi-typescript, Hey API, or UIGen. Any frontend stack can consume the spec.
Scaffold Dockerfile templates with `fastbackend init --docker` and build with `docker:build`.
Core IR engine, FastAPI runtime, and CLI are ready for local development.
