## What it is
A Ruby gem that extends the Devise authentication framework for Rails with invitation functionality. It lets authenticated users invite others by email, with invitees accepting by setting a password.

## Use cases
- add invite-only user registration to a Rails app
- let existing users invite friends by email
- build admin-invited team member onboarding
- implement invitation tokens with expiry and acceptance tracking
- limit how many invitations each user can send

## When to choose
- you already use Devise for authentication in a Rails app
- you need email-based invitations with token acceptance flows
- you want a mature, widely used solution with generators and migrations

## When to avoid
- your app does not use Devise or Rails
- you need open registration rather than invitations
- you use a non-Ruby stack

## Facets
- artifact type: library
- maturity: active
- function: auth, email, plugin-system
- domain: web-development, backend, security
- platform: ruby
- tags: rails, devise, user-invitations, authentication, web-server
