Doorkeeper is a Ruby gem (Rails engine) that adds OAuth 2.0 provider functionality to Ruby on Rails or Grape applications. It implements the OAuth 2.0 authorization framework including authorization code, client credentials, password credentials, and implicit grant flows, plus token revocation, introspection, and PKCE.

Use cases

• add OAuth 2.0 provider to a Rails app
• issue access tokens for a Grape API
• implement authorization code flow with PKCE
• support token revocation and introspection endpoints
• secure an API with OAuth 2.0 access tokens
• manage OAuth applications and scopes for third-party clients

When to choose

• you need your Rails or Grape app to act as an OAuth 2.0 authorization server
• you want a mature, spec-compliant OAuth 2 provider with broad RFC coverage
• you need flexible ORM support (Active Record, MongoDB, Sequel, Couchbase)

When to avoid

• you only need to consume OAuth 2.0 tokens as a client rather than issue them
• your app is not built on Rails or Grape
• you need a standalone identity provider service rather than an embedded engine
