Grape is an opinionated Ruby framework for building REST-like APIs, running on Rack or alongside Rails and Sinatra. It provides a simple DSL with built-in support for versioning, multiple formats, content negotiation, and parameter validation, with a companion grape-swagger gem for API documentation.

Use cases

• build a rest api in ruby
• create versioned json api endpoints
• add an api to an existing rails app
• mount a rack-based api microservice
• generate swagger docs for a ruby api
• validate and coerce api request parameters

When to choose

• you need a dedicated REST API layer in Ruby with versioning and content negotiation
• you want to complement Rails or Sinatra with a lightweight API DSL
• you prefer declarative parameter validation and auto-generated Swagger docs

When to avoid

• you are building a full web application with server-rendered views
• you need a framework outside the Ruby ecosystem
• you want a non-opinionated, unstructured API layer
