## What it is
Sinatra is a Ruby DSL for quickly creating web applications with minimal effort, built on Rack. It provides routing, filters, sessions, and support for many template languages in a lightweight microframework.

## Use cases
- build a small web api in ruby
- create a lightweight web app without rails
- serve json endpoints quickly
- prototype a web service
- build a webhook receiver
- create a simple website with templates

## When to choose
- you want a minimal ruby web framework with a simple DSL
- you need a small service or api without rails overhead
- you want fine control over rack middleware
- you're building microservices or small endpoints

## When to avoid
- you need a full-stack framework with batteries included like orm, auth, and asset pipeline
- you're building a large monolithic web application
- you're not working in ruby

## Facets
- artifact type: framework
- maturity: stable
- function: web-framework, routing, templating, middleware, http-server
- domain: web-development, backend, apis
- platform: ruby, cross-platform
- tags: dsl, rack, microframework, minimalist, rest, web-server
