## What it is
Cuba is a Ruby microframework for web development built on top of Rack, inspired by the Rum request mapper. It offers minimal routing with composable matchers, template integration via Tilt, and testing support through Cutest and Capybara.

## Use cases
- build a small Rack-based web application in Ruby
- write a lightweight API with minimal routing
- create a microservice with minimal dependencies
- learn minimalist Ruby web development
- serve simple pages with template rendering via Tilt

## When to choose
- you want a tiny, dependency-light Rack framework
- you prefer explicit, composable route matchers over DSL magic
- you're building small apps, prototypes, or microservices in Ruby

## When to avoid
- you need batteries-included features like ORM, background jobs, or asset pipelines
- you're building a large application and want a full-stack framework like Rails
- you need a framework with a large active community and ecosystem

## Facets
- artifact type: framework
- maturity: maintenance
- function: web-framework, routing, templating, middleware
- domain: web-development, backend, apis
- platform: ruby
- tags: rack, microframework, minimalist, tilt, web-server
