Deploy and Host a CRUD API Builder with Railway

A production-ready FastAPI + SQLModel CRUD API with PostgreSQL storage, 6 REST endpoints, automatic OpenAPI docs, health checks, and CORS support. Deploy in one click with Railway's auto-detect — no Dockerfile needed.

About Hosting CRUD API Builder

The app uses FastAPI with SQLModel (SQLAlchemy + Pydantic) for PostgreSQL ORM. On startup, it auto-creates database tables from your Python models. The API includes full CRUD operations with proper HTTP status codes (201 for create, 204 for delete, 404 for not found), pagination via skip/limit, and automatic schema generation at /docs and /redoc.

Common Use Cases

Mobile app backend — Instantly deploy a REST API for user data, notes, tasks, or any CRUD resource
SaaS MVP — Skip the boilerplate; start with a working data layer and customize from there
Hackathon starter — Deploy a fully functional backend in under 2 minutes
Learning reference — Clean, well-structured FastAPI + SQLModel + PostgreSQL example with tests
Microservice — Lightweight API service in a larger architecture
