Doorkeeper is a battle-tested OAuth 2 provider for Rails applications, making it possible to issue and validate access tokens for client applications.
It supports standard OAuth 2 flows such as authorisation code, client credentials, and implicit grants. Setup involves installing the gem, running its generator, migrating the database, and configuring scopes and flows in an initializer.
Doorkeeper is actively maintained with clear documentation and guides. Its standards compliance and flexibility make it stand out, while its weaknesses are setup complexity if OAuth isn’t strictly required.
Alternatives include using Auth0 or Okta for hosted identity solutions, or devise-jwt for simpler token-based APIs.
