A collection of contributed Rack middleware components and utilities for Ruby's Rack web server interface. It provides dozens of small, composable add-ons such as IP access control, JSON body parsing, JSONP support, response caching, locale detection, and exception mailing.

Use cases

• add JSON request body parsing to a Rack app
• restrict access to a Ruby web app by IP address
• cache responses to disk like Rails page caching
• detect client locale from Accept-Language headers
• email exceptions with stacktrace and environment details
• add JSONP support to a Rack API
• put up a maintenance page for a Ruby web app

When to choose

• you maintain a Rack-based Ruby web app and need small composable middleware pieces
• you want utilities like JSONP, nested params parsing, or response caching without pulling in a full framework
• you need simple IP-based access control or maintenance-page handling at the middleware layer

When to avoid

• you use a modern framework like Rails or Sinatra that already bundles equivalent middleware
• you need actively developed features with frequent releases
• you are not using Ruby or the Rack web server interface
