## What it is
A Node.js CLI tool that turns a JSON file into a full fake REST API with CRUD endpoints, filtering, and pagination in seconds. It is widely used for frontend prototyping and testing without a real backend.

## Use cases
- spin up a fake REST API from a  file
- mock a backend for frontend development
- prototype an app before the real API exists
- test http clients against a local rest server
- create dummy endpoints for demos
- serve  data as an api

## When to choose
- you need a quick mock REST API with zero coding
- you are building or testing a frontend without a backend
- you want realistic CRUD endpoints for demos or tutorials

## When to avoid
- you need a production backend with auth, validation, or persistence
- you need GraphQL or non-REST protocols
- you need fine-grained custom business logic in endpoints
