## What it is
Caffeine is a lightweight REST service written in Go that stores JSON data with CRUD operations, JWT auth, schema validation, jq-style search, and SSE realtime notifications. It requires no database setup, supporting in-memory, sqlite, postgres, or filesystem storage, and auto-generates Swagger/OpenAPI specs.

## Use cases
- prototype a backend without setting up a database
- spin up a quick REST API for an MVP
- mock backend for frontend development
- store JSON data with simple CRUD endpoints
- add JWT auth to a throwaway API
- get realtime data change notifications via SSE
- auto-generate OpenAPI docs for a test API

## When to choose
- you need a working JSON backend in minutes for prototyping or MVPs
- you want zero database setup with optional sqlite/postgres persistence
- you want built-in auth, validation, search, and Swagger docs out of the box
- you want an easily deployable containerized backend stub

## When to avoid
- you need a production-grade backend with complex business logic or relations
- you need high scalability or advanced query capabilities
- the project sees infrequent releases and you need active long-term support
- you need non-JSON data formats or GraphQL
