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
