## What it is
Scotty is a lightweight Haskell web framework inspired by Ruby's Sinatra, built on the WAI interface and the fast Warp web server. It lets developers define RESTful routes declaratively with verb, URL pattern, and handler, and supports middleware, cookies, sessions, and monad transformer integration.

## Use cases
- build a REST API in Haskell
- write a small Sinatra-style web app
- serve JSON endpoints with Warp
- add cookies and session management to a web app
- prototype web services quickly in Haskell
- compose WAI middleware like logging or header validation

## When to choose
- you want a minimal, declarative Haskell web framework with low ceremony
- you need RESTful routing on top of the fast Warp server
- you want template-language-agnostic responses (any Text value)
- you need monad transformer support to embed custom stacks

## When to avoid
- you need a full-featured framework with built-in ORM, auth, or templating
- you're building large production apps needing heavy ecosystem support
- you're not working in Haskell

## Facets
- artifact type: framework
- maturity: active
- function: web-framework, routing, middleware, http-server
- domain: web-development, backend, apis
- platform: cross-platform
- tags: sinatra-inspired, wai, warp, rest-api, haskell, dsl, web-server
